Hi Ville,

Regarding recovery from reboot: I looked at the code, and it seems that while the channel 1 and channel 2 settings are stashed and restored, the auxiliary channel setting was not. This is why after the reboot, you were connected to the aux channel but with the default setting (aux voltage DC). I’ve patched this in firmware and will release it shortly. Thank you for finding another edge case.

Regarding why we reboot at all: Honestly I’ve struggled with this a lot and I don’t have a great answer. It’s quite hard to diagnose because it only happens once after a few days. It seems to happen in the SD card initialization period when the meter is waking up to take a reading, but that’s about as far as I’ve gotten. So far, making reboot recovery robust has been a good time investment compared to the weeks I spend chasing flaky errors.

Thanks again, best
