This morning for the first time, my P110 smart switches were OFF. They are all set to be permanently ON, and to default to ON after power outages.

Since I use these to monitor the power usage of my two fridges and a freezer, I have had my confidence severely shaken. If I hadn't noticed I would have a large bill for wasted food.

The only possible cause of this that I can think of is a buggy firmware version. All three of my independent P110s went off at 2am, a typical auto-update time.

Does anybody know what happened and did anybody else experience this?

Will setting "on" timers on the device act as failsafes even if the WiFi is down?
