Transmission

To set up your own transmitter, follow the pairing-process as follows:

  1. optional: create and adapt config.json to set a custom address for the new transmitter
  2. long-press the PROG-button on a paired remote until the device (e.g. a shade) jogs
  3. transmit the prog command with transmitter.py. The device will jog again indicating that a new transmitter is paired
  4. send regular commands
$ sudo python3 transmitter.py down
key: 0xA0, ctrl: 0x04, rolling code: 0x03, address: 0x365240
cksum: 8
Data: 0xA3 0x48 0x00 0x03 0x40 0x52 0x36 
Frame: 0xA3 0xEB 0xEB 0xE8 0xA8 0xFA 0xCC

The rolling code is automatically incremented and saved to config.json.
