No data (yet) for selected period

Well I haven’t brewed in a while (a month or so) And getting ready to brew tomorrow. Setting up my fermentation profile I noticed the Graph Widget is displaying “No data (yet) for selected period”.

When I click “Show Full Widget” I get “Request failed with status code 500”.

Not sure what to try…

Have you updated your system?
Could you please run brewblox-ctl log?

If so inclined, you can also open browser dev console, go to network tab, and refresh to trigger the error again.

Seeing under voltage, I guess ???

The relevant error is sockets suddenly being closed. The constant spam of undervoltage errors makes it very likely that this is the underlying problem.

@Bob_Steers, Found my spare power supply and I have graph data. Fingers Crossed !!
