My heat pump had also thrown an error, but because it sits in a closet (the indoor part anyway), and we don't use its tiny screen for slow TV, nobody noticed until it started getting cold. To make things even worse, the heat pump resets its error messages every 24 hours and retries, removing the error message in the process, so you may check on the heat pump and it shows zero error, yet 30 minutes later it calls for technical service.
I ended up installing an eBus shield in mine. It is a €50 ESP32 device that reports data to MQTT, and HA can pick it up [1] from there.
Things went a little overboard from there, so there's smart electricity meter monitoring, water meter monitoring, automatic valve controllers on main valves, basically anything "house" can be monitored and controlled from HA.
On the bright side I have very few smart light installations. Lights are more or less a solved problem in my book. 100+ years of electricity has pretty much revealed the optimal placement for light switches, and while some lights truly benefit from smart bulbs or relays, the majority doesn't (in my home).
5-10 years ago I didn't care if smart technology had local control, today I won't purchase anything that doesn't allow me to control it locally in some fashion. I don't mind having to tinker a bit with ESPHome or MQTT, that's fine, and for the vast majority of people, a cloud integration is probably the right solution, but I want the ability to operate my devices completely off grid if need be.
