The GD00Z-4 is a Z-Wave device that connects to your garage door opener, and lets you open or close your garage door as well as monitor its status.
While It is compatible with almost any automatic garage door opener connected to a sectional garage door, it did not work for my particular garage door. Simply connecting the GD00Z to the trigger inputs on my garage door opener, as per the installation instructions, did not work:
As a reference, I have the LiftMaster MyQ model: 7675:
The following steps explain a workaround for this particular LiftMaster MyQ garage door opener to be controlled by the GD00Z-4. The same approach may work for other garage door openers.
* Soldering iron.
* Safety glasses.
You will need to connect the output wires from the GD00Z-4 to the wall button directly instead of the garage for opener.
You will need to remove the wall button from the wall, open it and solder the wires to a surface mount circuit board button then re-assemble the button, re-install the wall button.
If your GD00Z-4 is plugged in, unplug it.
Locate the wall button and remove it. (You may have more than one, be sure to locate the correct one).
Once removed, turn it over, and you'll notice that it contains a small circuit board. (We will be soldering our GD00Z-4 wires to this board.)
Unscrew the two screws (in this case labeled Red and White) that connect the wires to your garage door opener.
Carefully remove the circuit board from the plastic housing, turn it over and note the small push button switch, in this case, labelled SW1. (We'll be soldering the GD00Z-4 wires to two legs of this switch.)
Solder the wires from the GD00Z-4 to the two legs on the switch as shown:
Note: You can use a multimeter to test the resistance of the two legs when the button is pressed to confirm the correct legs.
* Reassemble the wall button.
* Re-connect wires you removed in step 2.
* Mount and plug in the GD00Z-4. (Note: The GD00Z-4 can now be located by your wall button. If you wish to have it next to your garage door opener instead, simply run a long pair of wires from the wall button to the GD00Z-4's wires. In other words, you are simply extending the length of the GD00Z-4's wires to reach from your garage door to the wall button).
* Pair to your Z-Wave hub if not already done.
* Test to be sure it functions as expected.
Below shows the GD00Z-4 paired with SmartThings:
Tapping the open and close buttons now operates the garage door as expected.
You can now add the GD00Z to Stringify...
...and use it in your flows.
In this flow example, I get a notification if my garage door opens and I am not at home.
