Para BG16441221615/10/2017Pay attention: current rating is no more than 15 Amps and with resistive load.
This is due to the relay HK3FF used inside Sonoff Pow.
If you have an inductive load (e.g. motor coil transformer etc.) rating will be much lesser maybe 5 Amps or less: it's not specified in datasheet!
About setup it is very easy.
Para ernie.88127/09/2017Works great with alternative Sonoff-Tasmota firmware (MQTT). Did not check original firmware because I'm afraid of spy functions in closed source firmware.
