A while ago I moved from an RPI3 setup to a HA Yellow one. I recently noticed that I have an integration called RPI Power Supply Checker.
At first, I thought I should just delete it but then I hesitated because I was thinking maybe it’s useful for my HA Yellow too. After all, the integration has a sensor saying “Power Supply Status: OK”.
What should I do?
If you are using the official PSU that came with the Yellow, the integration is unlikely to trigger, but I’d leave it in case a fault lowers the supply voltage - which can lead to data corruption.
The RPi4 CM in the Yellow has the same Power Management Integrated Circuit (PMIC) as the RPi4, so the same integration will work.
The RPi5 CM also works the same if you upgrade the Yellow.
