Ok. Is this LiftMaster MyQ ? If so, which version.
The color of the programming buttons is one way to identify the version.
Depending on the version, you may be able to use Dominick Meglio's (@dman2306) port of the MyQ Lite driver from SmartThings. That's what I have and use. It works well, but you need to add a contact sensor or tilt sensor to sense that the door is closed. I use the Aeotec Door/Window Sensor 7. The easiest way to install this driver is through Hubitat Package Manager (HPM), a program that Dominick Meglio (@dman2306) wrote.
Here is the link to the MyQ Lite community driver:
One disadvantage of using this approach is that, every now and then, just to annoy, LiftMaster/Chamberlain changes their API (Application Programming Interface), and the Hubitat MyQ Lite driver breaks until Dominic can figure out the change and work around it.
A second disadvantage of using this approach is that the API is through the cloud to LiftMaster/Chamberlain's API server. When your cloud goes down, the Hubitat control goes down because the driver cannot connect with the LiftMaster/Chamberlain server.
A second approach is to hardware a controllable relay to your switches, and have the relay momentarily "push" one of your switches. I've got a Zooz ZEN16 MultiRelay that can do that, and some use the Zooz ZEN17 relay. There are a few threads in the forum on how to wire that up. Here, for example, is one:
An advantage of this approach is that it is completely local, and does not go down if your path to the Chamberlain/LiftMaster server goes down, and it is not hostage to API changes that Chamberlain/LiftMaster might make.
Hope this helps.
