I was able to get full functionality with the Linear GD00Z controller and a Smart LCD wall controller. It did take custom integration work.
Installation Overview
Instead of trying to trigger the opener directly, we’ll use the Linear GD00Z to close a relay which will close the button contacts on our smart controller and thus open our door.
Materials and Supplies
- 4 wires (instead of the standard 2) from the opener to the smart controller. Alternatively you can mount the Linear GD00Z on the wall next to your smart controller. I used 18/5 thermostat wire.
- A 12-volt automotive relay. The Linear GD00Z doesn’t produce enough voltage to trigger the smart controller. It will however close a relay.
- An additional 12-volt DC power supply. I had an extra lying around from an old wireless router.
Step 1: Solder contacts to the smart lcd controller contact buttons
Since the smart controller multiplexes the signals to the opener rather than closing/opening a circuit like a dumb button, you need to use the smart controller to trigger the opener. Start by soldering two short leads to the “open” button on the smart controller.
You are looking for the contacts for either of the blue buttons at the top.
I added quick disconnects to the wires to make installation easier.
Wire the red and white thermostat wires to the standard controller contacts. Choose two other wires to connect to the newly soldered contacts. I used blue and yellow.
Step 2: Connect the wires to the relay.
The wires running to your smart controller (blue and yellow for me) connect to two poles of the relay. Make sure you connect them to the output poles - not the poles which actually close the circuit. Mine were sized for the quick disconnects so wiring was easy. The negative wire from your 12V power supply hooks to one of the input poles on the relay. The positive wire from the power supply connects to one of the Linear GD00Z wires and the other wire connects to the last pole on the relay. In other words, the positive wire from the 12V power supply goes through the Linear GD00Z to connect to the relay.
Step 3: Connect the Smart Controller To Your Opener
The red and white wires connect to the opener as normal. Plug the opener, Linear GD00Z and the relay power supply in and test the whole system.
My smart controller is fully functional and my Linear GD00Z is as well.
