Hi all, I'm playing round with Assist, testing different LLM's, tools, etc. What i was missing from HA is a card which shows the past conversations, including processing times and such.

After a bit of experimenting i got a working PoC and then expanded on it.

Current features:

Features:

- Shows Assist pipeline debug runs end-to-end (STT → intent → TTS) with timings and status.

- Browse recent runs, select a run, and inspect each stage’s inputs/outputs.

- Raw JSON events viewer for the full payload.

- Live “thinking” stream while a run is in progress (useful for diagnosing slow/failing runs).

- audio visualization modes for TTS playback (waveform/spectrum/meter/glow/“Ulysse31”).

I would love some feedback from other HA users =)
