I just had a go at installing my broadlink light switch tonight. It blew up, which was unexpected. On the second try however, the light came up but unfortunately, it wouldn’t go off again and produced a burning smell. It comes with a little capacitor thing and instructions to install it into your circuit someplace if using LEDs or power saver bulbs, alas, the instructions tend towards the vague relating towards where to put it (the diagram looks like the light pendant) and all the help videos on you tube appear to be in Russian.

The hub arrives soon so will try again then.
