I'm tinkering with my garage door motor (Marantec Comfort 220) which have a RJ11 6-pin connector (X10) for an accessory relay board. The relay board is quite expensive and I don't actually need the relays.
The board consists of three (3) relays driven via the RJ11 connector.
Solved: I'm using the following pins for the outer RJ11 connector (X10) on the board:
- GND Garage light
- All relays, 24 V
- Close with 5
- GND Door open
- Close with 3
- GND Door close
