I have many of the Sonoff Pow R2 switches on use.
I have some situations where i do not use the On/Off switch at all.
Like in my Solar-Plant it is used only for the amount of power it is creating.
Or in my Security Camera system i also need only the power amount it is using.
In both situations it will harm the devices if they are powered off accidentially.
So it would be nice in the setup to enable/disable the switch.
