Suddenly Stopped Working about solarshed HOT 2 OPEN

Was this ever resolved? This just happened to me, I was working on an unrelated project and it just stopped working.

OSError: No communication with the instrument (no answer)
problem updating gauges

Hi folks - I've not encountered this one before. The Raspberry Pi I had installed in my "original" solar shed trailer just expired -- so I might try to do a "fresh setup" to a) document it and b) see if I encounter anything like this one.

If I find anything helpful, I'll report back
