I was outside minding my own business when my Spark V2 started beeping repeatedly about once a second. The screen was also flashing as if the Spark was rebooting at that frequency. I immediately unplugged the USB cable (from the Pi side). When I reconnected the USB power cable I got no response from the Spark; no beeps and the screen stayed blank. I tried a different USB cable on a laptop and still nothing. Last, I tried the 12V power supply from my Spark V3 and still nothing. The status LED is also blank, though there is a green LED inside the case that lights, which is the only sign that anything happens when power is applied.
This Spark has been running for years from the same RPi 3 and USB cable. For almost all that time it was running BrewPi software. However, on 22 Mar 2020, I upgraded to BrewBlox. The upgrade went smoothly as did setting up the Fermentation fridge profile. The Spark ran fine till today. I’m not sure if the upgrade is related (doesn’t seem like it would be), but sharing just in case.
Help!? @Elco ?
