I set up a VPE for testing, and disabled the LED ring via the config in HA.
Occasionally I see that the lights light up and it does something. Usually it's the red ring.
I've looked in my logs for HA, and see:
2025-02-14 16:50:23.300 WARNING (MainThread) [aioesphomeapi.connection] home-assistant-voice-09d577 @ 192.168.3.2: Connection error occurred: [Errno 104] Connection reset by peer

Which tells me that the VPE is disconnecting at somewhat random intervals.
I also the network from my router, and see that at the time of these disconnects being logged, I also see different than usual behavior on the network.
It starts an entirely fresh DHCP flow (instead of just lease renewal), and then sends a RST to HA on the next TCP frame. (These frames happen roughly every 40s).
I suspect that it reboots, but don't know exactly why. I've already swapped the power converter to one that should be overkill.
