I have found that the control of the simple Livolo switch VL-C301 is rather haphazard, the OFF command seems OK but ON would only react correctly 50% of the time. However treating the switch as a dimmer, level 0 for OFF and level 3 for ON, shows real promise.
Has anybody else tried this.

I use php/json and so I need to use the IDx value. If the device IDx # were displayed on the switches page it would be a help.
