I have never heard of Matter before, but I was super satisfied with Ikea's zigbee products. Does anyone know why they switched?
frenchtoast8•1h ago
It’s less of a switch and more of an upgrade. The hub will continue to work with Zigbee devices, it just adds Matter support to those devices you already have.
wlesieutre•1h ago
Might be an upgrade if you're using devices through Ikea's hub, but if you've been buying Ikea's zigbee devices for use with some other zigbee network it's a bummer that you won't be able to get them anymore.

Even if you're all in Ikea's ecosystem it will still mean whatever new devices you add from now on are a separate mesh network and can't use the existing zigbee products as repeaters. If the next thing you want to add is at the far end of your house from the hub, it won't have reception there with Matter until you put other new devices in between.

pta2002•1h ago
It’s a newer standard backed by multiple vendors (importantly, Apple, Google and Amazon, who make the devices that you ultimately want to use to control these things).

Zigbee is great for communication instead of WiFi, but it’s just one part of the equation - it says nothing about the specific commands a device will respond to. You couldn’t pair a Philips remote with an IKEA lightbulb.

Matter attempts to fix it by actually defining the protocol that these devices use. It’s also fully local and open source, which is great. The actual transport layer can be WiFi, but it can also be Thread, which is a newer standard based off Zigbee, and AFAIK some Zigbee controllers can be reprogrammed to support it.

They don’t specify what transport layer they are using here, but considering the kind of devices they are showing (battery-powered remotes) it’s almost definitely Thread.

noir_lord•1h ago
Matter is definitely a step in the right direction, SDK is under Apache and the actual spec is freely available[1]

Might give it a year or three and if they continue on that path I might have to reasses my "No smart devices in the house" "rule".

milliams•1h ago
https://www.theverge.com/tech/814928/ikea-matter-thread-diri... has some quotes from IKEA saying that they're using Thread. It's strange they didn't say in this release though.
pta2002•1h ago
I guess because to most consumers, it doesn't actually matter. It uses matter and connects to a matter hub, the way it does it is an implementation detail unless you're making your own hub with homeassistant or something.

Even iPhones have been able to talk to thread devices directly for a while now, so it's a fairly transparent process.

teamonkey•1h ago
The way I understand it (please correct me) is that:

* The old Ikea Zigbee products will remain Zigbee. They will still require a Zigbee coordinator.

* The new products will be Matter-over-Thread. They require a Thread coordinator (or whatever the Thread equivalent is called).

* The existing Ikea hub has had a firmware upgrade that allows it to be simultaneously a Zigbee and Thread coordinator.

* The Ikea hub adds a Matter compatibility layer to the devices that don't natively support Matter.

j45•1h ago
Helpful datapoints thanks.

Backwards compatibility is huge.

teamonkey•1h ago
I could be wrong! I'm trying to work out the details myself!

But I have heard that old devices will be backwards compatible.

Latitude7973•1h ago
> or whatever the Thread equivalent is called

Thread Border Router (for info).

gorbypark•10m ago
This is correct more or less. The Ikea hub has had the ability to bridge its zigbee devices to Matter for a while now. So in my case, Apple Home has no idea my lights and switches are not Matter, they just show up there even though they are actually zigbee.

Ikea recently did an update to enable the hub to be a Matter controller itself (over thread or Wifi). This means you can add matter devices to the Ikea hub directly and use the Ikea Home Smart app the control them instead of Apple Home or etc. You can add non-Ikea matter devices as well as Ikea matter devices (when they are released).

close04•1h ago
Zigbee is the wireless network protocol. The equivalent to it on the Matter side is called Thread, also based on Zigbee from what I read (was developed by Connectivity Standards Alliance, formerly known as Zigbee Alliance). Zigbee and Thread operate at OSI L1-3, Matter is L3/4-7.

Matter is a communication protocol adopted by a lot of manufacturers but I think practically for the buyer the real benefit is that you no longer need a bucket of hubs for each of the device ecosystems one might use. It's more future proof so it makes sense IKEA would add support for it in their hardware including existing hubs I believe.

darkwater•1h ago
You never needed a bucket of hubs with things like zigbee2mqtt or the Zigbee implementation in Home Assistant. That's enough a proof that the issue was not in the protocol. Actualyl you can also pair between them different vendors products (i.e. Ikea remote with Philips bulbs)
pta2002•1h ago
While you could do that, the hub needed to implement the logic to actually convert the different "APIs" that the products spoke. E.g. imagine an IKEA remote sends "button_on" to turn on the light, but the Philips remotes send "light_on" or something. Philips lights will work with their remotes but not with IKEA remotes, since they wouldn't know what to do with "button_on". Zigbee2mqtt and ZHA are great projects that implement a compatibility layer to all of this, but they do have to explicitly support every device (and they support basically _every_ device there is, thanks to a ton of community work, they're genuinely great projects and something that wouldn't really be possible without open source). You mention that you can pair between different vendor's products, but that's not quite the case - you can pair different vendor's products to the hub, and the hub can translate between them. But while you can pair an IKEA remote to an IKEA bulb without a hub, you can't really do that between different brands.

Matter simplifies this. It defines the API layer. You can use Thread without Matter, at which point you basically have Zigbee + IPv6, but the power comes with Matter since now every device is speaking the same language and can actually understand each other.

darkwater•23m ago
> you can pair different vendor's products to the hub, and the hub can translate between them. But while you can pair an IKEA remote to an IKEA bulb without a hub, you can't really do that between different brands.

Yes you can, I did that with Ikea, Philips and Innr brands. No hub, not even Z2M involved. Yes, as you say they do need to agree on a "protocol" and AFAIK they are all following Philips lead on that, but they can totally work in a P2P fashion without any hub. They negotiate their own key, you just need to pair them with a very close distance (less than 5cm approx).

close04•23m ago
> You never needed a bucket of hubs with things like zigbee2mqtt or the Zigbee implementation in Home Assistant

That works, I am doing the same. But the average consumers don't want to be bothered to run HA, they want things to work out of the box with minimal fuss setting up or operating. This usually meant having the Philips hub, the IKEA hub, the Samsung hub, etc.

> That's enough a proof that the issue was not in the protocol

For sure not in the Zigbee protocol, which is standard. The differences are in the logical communication protocol, at application level. Each manufacturer wanted to fully control their product, with no alignment with other manufacturers, which made devices and hubs mostly incompatible outside of each ecosystem. This is what Matter is looking to fix. One controller coordinating over a standard protocol a bunch of IPv6 devices connected via WiFi, Ethernet, or Thread.

And best part, Matter certification means the devices have to be able to operate locally. No more "cloud polling" [0] type integrations even for basic functions.

IKEA's Zigbee devices have been some of the more stable smart devices I owned. I wasn't running their hub, opting to run with deCONZ in the past and moving to Zigbee2MQTT in recent years.

I do wish the new range would include blinds; the previous generation (FYRTUR) is out of production, and it doesn't seem like there's a replacement yet.

metadat•1h ago
Fwiw, Smartwings blinds are cost effective and have worked great for me for years now. Cone in both z-wave and zig flavors.
scosman•56m ago
Word on reddit is they discontinued the blinds due to reliability problems. I have 3 and 1 failed so makes sense to me. They want to bring them back, but it's a complete redesign, not just normal planned product lifecycle iteration.
ericd•25m ago
I hope they make them quieter this time!
greggsy•12m ago
I have non ikea electric blinds. Sure they’re a a little grindy but it’s like 30 seconds two a day.

FYI someone made their own firmware which will drive the motor at a slower speed. Significantly reduces the noise.
deanc•23m ago
Using the blinds with a second gen hub now for about four years. No problems at all. Dreading the day they fail as they’re non-negotiable during the summer.
afavour•15m ago
FWIW I bought some Zigbee blinds from Amazon and they’ve been great. My windows weren’t the right size for the IKEA ones and the sellers on Amazon will custom make them for you to within 1/8 inch or something like that.
bjoli•22m ago

embedding-shape•2h ago
Does this mean they're abandoning Zigbee compatibility? In my experience, Ikea was making the most reliable Zigbee devices considering the price (as someone who just uses Zigbee and no Ikea hubs, just HA+Zigbee), and would be a shame to lose that, but maybe it's a clear sign I should investigate starting to use Matter more instead?
j45•1h ago
Investigate using home assistant and keep using both from one place.
james-bcn•1h ago
Isn't Matter derived from Zigbee?
devttyeu•30m ago
Both use 802.15.4 but iiuc zigbee does that with some incompatibilities.
gorbypark•20m ago
Yes and no. Zigbee is both the transport and the protocol, whereas Matter is a protocol but can run over different transports. Most common in Thread or WiFi, but it could be over ethernet or anything else, really. I would say Matter is not derived from zigbee, but Thread could be considered a derivative.
jeroenhd•1h ago
The new Dirigera hub supports both for now (https://www.ikea.com/gb/en/customer-service/knowledge/articl...) so they'll probably slowly transition.

It depends on your setup how easy it would be, but the Zigbee stick I use for controlling Ikea stuff also has firmware available for using it with Matter. There's a good chance whatever IoT solution you use can be hooked up to Matter.

bluGill•1h ago
Matter is now a standard not just a common spec. Everyone should demand all new smart home devices support matter. (it is okay if you use Zigbee or some other alternative to control it today but you should still demand matter for the day you switch - that day should come)

In particular note the bane of all smart homes: if you have to move the next owner won't have a clue what you did. In the worst case you have to hire an electrician (no DIY allowed since it isn't your house anymore) to rip that out so your house is livable. If you are using matter there is a chance they can start using your system in their own way. The more matter takes off the more likely this is. Also the more likely others will use it - perhaps you next house will have matter installed for you and so you can just automate it where you want to instead of rewiring the house first.

guerrilla•1h ago
So, right now I use a Zigbee dongle on my a Raspberry Pi. Is that goimg to be possible with Matter?
nexus7556•1h ago
Yes, here is the one I use https://www.home-assistant.io/connectzbt1/
kristofferR•1h ago
Matter is just the software. A lot of Matter devices use Thread as their radio protocol (think of it as "Zigbee 2.0") though, and you need a separate radio/dongle for that.

Seems like Home Assistant will launch a combo Zigbee/Thread dongle with great range in two weeks, might want to wait for that: https://old.reddit.com/r/homeassistant/comments/1opak9w/new_...

guerrilla•1h ago
Right, that sounds familiar. It's been so long since I've looked into this. Thank you.

Someone1234•51m ago
More information here:

https://wizzdev.com/blog/how-much-does-it-cost-to-launch-mat...

But, yes, Matter/Thread is more expensive than Zigbee by a lot.

Ajedi32•40m ago
I wasn't aware of that. One other concern I have with Matter is that, if I understand correctly, Thread+Matter devices get their own IP address with internet access, whereas with Zigbee all of that has to be controlled by the gateway.

In theory that's a win for Matter, but I'm a little concerned about the security and enshitification problems that might cause. I kinda like the idea that I can buy a cheap IoT lock off Temu and as long as my Zigbee gateway is secure there's very little chance of that decision coming back to bite me...

ocdtrekkie•48m ago
Definitely will not be buying Matter stuff. Way too complicated, doesn't address the real problems in smarthome technology.

I usually take my smart devices with me when I move. It's a pretty expensive thing to leave behind for a new owner that probably won't use it anyways. If someone offered me extra to leave them I might and then I'd also leave a manual.

devttyeu•24m ago
It does address quite a few reliability issues - you can have multiple gateways into the thread network so it is actually highly available.

It’s definitely complicated, but it’s a kind of usb-c of smart home - you only worry about the complex part when building a product. Just wish there was a better device reset/portability story.

kyriakos•11m ago
you can get a Zigbee / Matter / Thread coordinator and continue using HA as before (google SMLIGHT)
nerdjon•1h ago
Is there an article that has the US pricing anywhere? It doesn't look like any of these are on the US site yet so I am curious what these will actually cost.

I keep hoping that Ikea would come up with something that can go over a switch to manually control it. Seems like it would be very much within Ikea's target market (renters). There are devices like this on Amazon but having used them in the past they are finicky at best.

conception•1h ago
When I rented I just replaced things and kept them in a box and put everything back when I left.
whitehexagon•1h ago
The ZigBee range used to include a bulb and remote, so you just leave the mains switch on.

Otherwise, I used floor lights in the past with WiFi switchable sockets before I switched to ZigBee. The WiFi ones wanted to dial home.

Mistletoe•1h ago
Tangential but I was wondering if anyone knows of a thermostat that can work with a security system for the most simple and accurate location sensing possible- when I press away on the alarm it turns the HVAC to eco type settings to save energy. I used to get this with Google Nest and location sensing from my phone but Google as always is killing my generation of Nest thermostat. I think I’d like to get away from location sensing entirely. Every time I leave the house I do the alarm, so that is all I need.
ramses0•1h ago
Certainly there's something with home assistant (or apple shortcuts) you can do? There's some nest firmware replacement that's a bit DIY, but HomeAssistant and friends will be the way to bridge between differing home automation bits/services.

If you are retrofitting a complete house at the same time, look at KNX. If not, do not explore this rabbit hole.
kevstev•55m ago
Can be relatively simple inside of Home Assistant. I have my alarm attached to Konnected, and that has an HA integration. I can both arm and disarm my alarm through an HA dashboard, and also have it arm itself if both myself and the wife are out of the house. You may not even need the alarm integration part- you can just use the home/away functionality and set the thermostat. The thermostat integration part I am less sure about, just because I haven't used it, but it should be fairly easy to set the set temps based on your home/away status.

Of course you need Home Assistant set up for this, but if you are interested in these types of things, it will be very useful.

What “hub” thing do I need to use this? I use an iPhone but really just want to use some physical remote switches.

You could get an IKEA Dirigera, but one of the upsides of Matter is that you do not need the manufacturers hub anymore. So an Apple Homepod or a Home Assistant instance with a Thread stick will do as well! (Or any other Matter hub for that matter of course)
petepete•1h ago

For some degree of future-proofing you'll definitely want a device with a Thread radio.

(I've done paid work on Matter so I'll avoid giving possibly-tainted opinions on any particular vendor's products.)

thedougd•1h ago
You're looking for a Thread border gateway. Lots of stuff already has it. Someone mentioned AppleTV and HomePod mini. Newer Google Nest speakers/displays have it as well.

But you can do it with just Home Assistant and a Thread radio: https://www.home-assistant.io/integrations/thread#turning-ho...

Personally, I pair my wifi and Thread matter devices to my Apple Home, as each Apple TV behaves as a redundant, ethernet connected gateway. I then do a secondary pairing to Home Assistant and Google Home. Local control and it works very well.

insane_dreamer•38m ago
Can't Matter devices connect directly to Apple HomeKit? So if you have a HomePod (or even a MiniPod though I'm not sure) it should connect all these Ikea devices too.

Their new smart plugs finally seem reasonably sized. I love IKEA’s smart home products, but their smart plugs (and many of their device power plugs) are comically sized in the US. Their original US version of the TRÅDFRI plugs wouldn’t even allow for two to be plugged into the same (standard size) dual wall outlet. Their more recent TRETAKT is much better, but still larger than competitors.

I've never really got the smart home thing, and the shit being pulled with the likes of "smart" TVs and cars has really put me off any sort of network connected device I can't control.

You can have both, Zigbee/Z-Wave devices are really easy to set up and they are purely local.
delecti•1h ago
It's not that complicated to get, some of them have useful features.

It's just a personal tradeoff between features, downsides, and risks. Most people don't consider the risks at all (implicitly down-weighting that factor), and the value assigned to the features and downsides varies by person. I have some smart lights, because I like the convenience of those lights being on voice control. My TV is "smart" but doesn't get internet because I don't consider the risk of ads acceptable.

ZigBee, Thread, and Matter are all locally controlled if you have a local controller that is controlled locally.

You'll still end up being an amateur network engineer though.

microtonal•41m ago
I don't have much experience with Thread + Matter (except the only device I have, an upgraded Eve Energy being a PITA), but for Zigbee/Z-Wave you do not have to be an amateur network engineer. Pairing is really straightforward and devices will automatically mesh and get routed by most mains-powered Zigbee/Z-Wave devices. It's not like you have to set up DHCP, manage an IP address range or anything like it.

As someone who is a bit of a luddite when it comes to smart home features, there are 2 things that really stand out to me that i would like.

1. Open/Close sensors, I would like to put sensors on my shed door and side gates that can tell me if they are open or closed. I will occassionally leave these open, or the kids may leave them open and would prefer they be closed each night. It's impossible for me to tell if they are closed at the moment without stepping outside.

2. Smart plugs. Being able to remotely operate / schedule plugs to shut off or on seems pretty nice. Outdoor lights being one usecase. Kids media area is another.

The solution is home assistant [0] it lets you manage and control all kinds of smart devices with a lot of customizable, hackable things. And it runs locally, so if you buy the right types of devices that don’t phone home to the cloud (or you shitcan their internet access) you can fully manage your own system.

Or if you want something more of an appliance, some other Hubs with Zigbee, Z-Wave, and Thread + Matter support are: Homey Pro, Homey Bridge, Aeotec SmartThings Hub, and Hubitat.

I only have experience with the first three (besides Home Assistant) and they work very well (though the SmartThings hub is somewhat limited when it comes to device support, graphing, etc.).

I should also mention that with Homey Bridge the dashboard is in their cloud, though the Zigbee/Z-Wave devices are fully local. Homey Pro is also local. (I think they have a Homey Pro Mini in the US now.)

rpcope1•1h ago
> any sort of network connected device I can't control. How would you use this and ensure privacy and security?

This was exactly the nice thing about Zigbee (and Z-Wave). They're not IP networks, they basically just work with any hub, and have no way of phoning home at all. You can use them with Home Assistant or other open source tools or write your own stack if you wanted. The thing that really blows about the switch to matter, is that it is IP based, and it looks like vendors will have another opportunity to tie specific functionality to their own hubs (and probably find a way to exfiltrate telemetry). There really wasn't anything wrong with Zigbee or Z-wave that couldn't be fixed in incremental protocol revisions (IMHO), but they don't generate money the way WiFi devices collecting telemetry or hardware churn for the sake of hardware churn does.

Before buying any IOT devices, see if you can download the firmware from the manufacturer's website. If you can't, do not buy that product.

I like Shelly's doodads. They are easy to work with, you can flash their firmware with an alternative if you want (Tasamota is popular). They have a decent onboard scheduler and the only app you need is a web browser pointed at its IP address. They don't need internet access.

Although I have been trying to only buy 'needs' not 'wants' recently, I did stockpile a few IKEA ZigBee gadgets before they retired them. One of the few product lines their MBA's hadn't destroyed.

I was working on some Golang code, talking to them via the very open ConBee II ZigBee gateway. Great fun, and very fast once I got subscribe vs polling working. So now I get an SMS for door access, but kinda hopefully never for a water leak.

No interest in yet another 'standard', especially since Matter seems to mandate PKI device attestation. ZigBee just feels more open to me, and I have enough eWaste devices with expired certificates.

Will zigbee2mqtt be able to talk to these? Or are they in a fully different type of network? If not, any other software that can do MQTT bridging with these?

I find pairing my IKEA bulbs and switches and whatnot to my Conbee 2 stick sometimes hard to do.

I'm thinking about buying a Dirigera hub instead, using that for the IKEA devices and using the Conbee stick only for non-IKEA products.

Does that work flawlessly when being controlled via HA or are there other issues to be expected?

edit: Maybe even ditch the Conbee stick after all, build some ESPHome devices as replacements (temperature/humidty - or wait for the IKEA version of that).

whitehexagon•1h ago
Agreed. I had no problem with the conBee II itself, but it did take me a while to figure out different IKEA ZigBee devices required different 'secret handshakes' to tigger pairing. eg number of button presses withing a second, I think one was 5x, another 4x, and lights were different again. Still, I prefered that hasle than having a hub dialling home.

But it was pretty stable once it was setup. Just occasional reboot on the rPI but I think that was my flakey SMS gateway code.

I just bought an AirGradient sensor and set up home assistant. What an absolute joy, both experiences (though I had issues building AirGradient's firmware due to some issues on their end, to their credit their dev team told me they're going to adopt my recommendations) are streamlined and professional and super easy to set up for a techie. I've already got in the habit of opening the window to the office as the sensor detects elevated CO2 (happens faster and more often than expected, very glad I invested).

However, I also bought a 3 SCD41 sensors and ESP32 C3 Superminis from the most reputable sellers on AliExpress, that's been an abject failure. I wanted additional sensors in other rooms less at risk, and wanted to try using ESPHome and putting together my own soldered little devices. Got counterfeit sensors (no laser engraving on the side as Sensiron indicates is without reception the case in genuine parts) and either counterfeit or defective microcontrollers (cannot connect to wifi, even 2.4GHz WPA2, a common enough problem from my research with ). The spread from reputable sellers in NA was absolutely ridiculous and worse then buying premade pieces by a large margin.

All to say, as fun as DIY is, I'm grateful to have trustworthy products available affordably. I'll still block internet access and leave them on a dedicated IoT VLAN, but I can at least not worry it's going to incorrectly label the air quality for a child's bedroom. I'll probably pick up 3 of the CO2 sensors from IKEA, if reviews look good.

I really hope that is CO2 and not eCO2.
scosman•48m ago
I suggest the SenseAir sensors. They don't seem as susceptible to fakes, and auto calibrate when exposed to fresh air. Supported by ESP home so build is simple.

Any evidence the Ikea sensor are actual CO2 censors and not just cheap "eCO2" sensors? Lots of the "CO2" censors our there are just cheap VOC censors with an calculation to estimate CO2.

I'm not investing in any smart home products unless:

* I can fully control them without the cloud on a non-internet connected network

* I can either pay for updates, or they have free updates for at least 12 years, ideally 15

If a hurricane or tornado strikes, or some dictator tries to tell me what I can and can't do, my devices need to remain under my command.

These are all Matter-over-Thread and meet your requirements, yay!

Elegrp switches can be used offline. They need to be provisioned online first though, unless you flash with esphome (which can't currently be done wirelessly), but then you'll have to write a custom integration config.

Pros: very inexpensive, and they look great. Cons: WiFi/ble only, they feel cheap, dimmers don't support a "transition" comment, so you cant dim over time easily.

I have accumulated so much smart-stuff fatigue, I can't stand anything branded as "smart". This means, as you point out, 1) any outage in the chain between me and the vendor's app shuts everything down for me, 2) stuff behaves inconsistently all the time. (e.g. Bluetooth speakers with a smartphone/tablet player app -- every other time something goes wrong: the app frozen completely because search autocomplete lost packets; you can't find the damn playlist buried in a sea of features; another your device wakes up and steals the bluetooth speakers.)

Regarding the electric switches, I was fond of bypass switches (where you can turn on/off by flipping any of the switches connected to a lamp) and made a lot of them in my apartments. Turned out not all of them were needed. I didn't need much control at home, e.g. I don't need to turn on the lighting above the kitchen desk when entering the kitchen.

Wifi switches would be cool, but it escalates everything to the unreliable realm of IP/internet devices. I'd probably vote for a controller on a lamp, and switches not actually inerrupting 230V~, but be connected with a thin and flat 12V= bus, and just signalling, and hence be easy to put under wallpapers. (5V= would be hard to send further than 3 metres.)

Modern smart switches are pretty small (most of them are designed to fit into wall sockets behind plugs/light switches).

I personally think relays are a much more reliable than solid state switches and are very unlikely to fail in a dangerous way, and fully interupt the circuit, but they do have a 'click' some people dislike, and have a lifetime of 100k-ish switches, so for an application where you keep switching rapidly (e.g. not light switches), this might be a problem.

Ikea used Thread and Zigbee which are not Wifi, they use a mesh network and don't suffer from saturation the way Wifi does, in fact adding more devices tends to make the network more reliable since devices can route around failing or congested nodes.

I've had good experience with them in practice, but do be mindful that they share the 2.4GHz band with Wifi so in an apt building, you might run into radio channel congestion.

Personally I use smart home stuff for controlling heating devices and a few other key items, I don't think it makes sense to make every light switch smart, but technically people have done so and it tends to work all right.

Currently renovating our house, everything will be KNX based. Offline, no servers needed (even within the house) but nice for visualization, standard, 500+ vendors of compatible hardware. Highly recommended.

All previous Zigbee and current Thread devices are physically incapable of connecting to the internet - the hub they talk to might, but since these are standardized (Matter and/or Zigbee define standard protocols for devices like this), you wont have problems picking another hub.

As for software updates, they can be updated, but these devices are so simple they can be reasonably bug free after a while - and security's not a concern (that much) since they don't really have internet access.

Some devices were known to have vulnearbilities where the attacker was physically present to get in radio contact with the device, but those are pretty rare and impossible to exploit en masse.

I realize Thread devices need a border router, but once they're connected to that router don't they get an IPv6 address with internet access? Or am I just misunderstanding the protocol?
torginus•3m ago
Not 100% sure about Thread as I'm more used to Zigbee, but afaik the Thread router acts as either a proxy between your regular network and the Thread devices (you can wrap IPv6 packets so they can be exposed over regular ethernet) or the router is the smart hub itself and the nodes are not really accessible from the Wifi network.

How it works in Home Assistant afaik is that the border router is a piece of software running in docker that has access to the radio, and then HA talks to the thread devices via the virtual network interface of Docker.

thedougd•45m ago
I really wish wall switches and dimmers were included in the first drop. I've long been in the market for affordable Matter over Thread switches with a matte white finish from a reliable vendor.

They need to cover all the categories too (single, multi-pole, dimmer, and maybe fan speed) so I know I won't end up with a hodge podge of brands and looks.

I'll keep holding out.

Is anyone aware of or working on an equivalent to zigbee2mqtt but for both Matter-over-WiFi and Matter-over-Thread devices?

It’s so darn convenient to have MQTT in the picture for home automation and my #1 challenge in imagining a future world past my 400+ ZigBee devices is what replaces zigbee2mqtt and has a similar “owner experience”.
