"Divide by zero" warning messages in PV_Opt #254

Closed punkymuzzle closed 3 months ago

Describe the bug Receiving warnings in AppDaemon which disappear after the service is restarted, but they just keep appearing. My logfile is full of them. AppDaemon log:

I Also seem to be getting warnings in the error.log:

Is this anything to be worried about? PV_Opt seems to be working (although sometimes the SoC level, charging rates etc seem to be a little weird).

Just realised there is an update available so will do this and then report back
