The Radio Control Action starts the process to send a control sequence over radiocommunication. The control sequence will be generated and send to the radio control transmitter (Broadlink RM pro or Intertechno ITGW-433). The Transmitter will send the sequence to your radio controlled receiver (for example a power switch).
You have to choose the Action Type „Radio Control Action“. Now you can configure the device and the control sequence (Radio Control Command), which should be sent.
If you define a delay, the action will be executed with the defined delay (specificaton in milliseconds). The parameter context is used only for some internal functionality within the IRControl System.
