One of my units was having some issues (could not connect via wifi), so I tried to do some troubleshooting. Ultimately removed the SD card, was able to mount it (Linux), and re-inserted it into the IoTaWatt with a different power supply. Booted fine, was up for ~6 minutes before I decided to try the original power supply again, and it has been unresponsive since. Get one blue blink on the ESP board and solid red on the IoTaWatt status LED when re-powering the unit.
In the 6 minutes it was up it transferred approximately 325MB of data; not sure if it was uploaded to Influx or downloading firmware. The unit is running 02.07.05.
What is the recommended next step? Update firmware with esptool?
