Good device for remote switching small loads ,using the associated remote controller
I bought this to radio controlled device to switch on and off a secondary hot water circulating pump in the house that I did’nt want on a fixed switched timer.
I chose to use the remote controller, a separate item that needs to be bought as the the app that also supports the device needs a subscription and always would require the use of a mobile phone.
The radio coverage is good with the transmitter in the kitchen and the receiver in the upstairs airing cupboard, All works together very well the signal passing through the ceiling and walls of the house.
