SOLVED The problem went away after yet another reboot of the raspi…
NOT SOLVED It came back after a couple of hours… :-/
I was using Brewblox until last week, when I bottled my last brew. I switched off my spark and fridge, the raspi continued to run. Today I wanted to use the fridge again, but brewblox won’t connect to the spark. I did not change anything in the meantime.
The spark is showing it’s assigned IP address (unchanged) and temperatures and seems to be working nicely. I can ping the spark from the raspi with low latency. It just won’t show up in brewblox.
I updated brewblox to the latest version, rebooted the pi - doesn’t help.
brewblox-ctl discover-spark does not find any devices.
It worked perfectly until I switched the spark off and on again, which is supposed to make things work, normally…
