"ReSpeaker Lite" - new Seeed Studio Voice Assistant Development Kit hardware combine ESP32 with XMOS XU316 DSP chip for advanced audio processing as a ESPHome-based Home Assistant Assist Satellite voice devkit

I seem to have understood that PIN D3 is not only linked to the physical button but also to the HA switch… can you confirm this? Because I removed the soldering and actually the Respeaker no longer mutes on HA.

Physically the button will mute the mic. But with unsoldered D3 there’s no way to do it from HA, because there’s no bond between XMOS mute button and ESPHome anymore.
That’s what I warned you about.
There is the way to know the state - but not operate it.

I thought it was just referring to the physical button… (which I don’t need). I’ll find an alternative solution…

can I power the Respeaker Lite from these two pins only?
any contraindications?

I do it in my devices. Works good.
