Our Module can be configured in three different ways:

  1. RASPBERRY PI HAT configuration

  2. DTMF CONTROLLER configuration

  3. GSM CONTROLLER configuration

They all control 433MHz relays or remotely controlled plugs wirelessly, so they are inherently safe as your Raspberry Pi or Arduino or Microcontroller is not connected directly with the high voltage relay or plug.



's three Modules in one and uses any old mobile/cell phone as a GSM controller. Many people use it as a cheap way of controlling their heating remotely.

1. It's a radio frequency (RF) transmitter which can turn remote control electrical sockets, like those below*, ON or OFF from ANYWHERE IN THE WORLD WITHOUT WIFI OR INTERNET.

2. It can also be used in conjunction with a cheap DTMF module to control up to 5 sockets from anywhere in the world.

3. It can be used with a microcontroller or Raspberry Pi or Arduino to SAFELY control mains voltages.

See Modes of Operation for a detailed descriptions.
