False idle system alert?

I received an “idle for more than 60 minutes” alert at 09:37 this morning.

It was quite cloudy, but the system was not idle, at least not in the hour before the email was received. I’ve noticed this happening a few times recently.

It’s only a minor irritation, but I wonder if something’s not right.

Your system wasn’t idle, but the data recording and/or upload was failing from 08:40 - 10:05 and 11:35 - 12:45
You can see a flatline for voltage and temperature. PVoutput will fill the missing values with the latest known value.
Your uploader will upload the missing power values (green line) afterwards but the voltage and temperature are lost.
You are probably using SBFspot with your SMA inverter? My guess
