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…
After everything worked fine yesterday after all the intermittent firmware problems, my problem returned yesterday evening, even though I didn’t notice until now. The spark is still showing a correct IP address, a green light, the correct temperatures and setpoints, but BrewBlox shows that the service is running, but can’t get a connection to the Spark.
This might be a problem with my Raspi and my home network because it’s showing some weird behaviour lately (discovery of upnp devices is sometimes a problem), but this hasn’t ever occured with Brewblox / Brewpi before.
