New Chamberlain Garage Opener

[JDRoberts]

The LFM20 Evolve relay is for lighting fixtures. That’s what it’s UL rated for. It is not UL rated to control a garage door opener. I know a lot of people use it that way, but you should be aware that that’s what you’re doing.

There are several alternatives that are UL rated for unattended garage door opening, including the Linear GD00Z, which is quite popular in the community

[OBSOLETE] Enhanced Z-wave garage door opener code (for Linear GD00Z and variants)

I’ve modified the ST default “Z-Wave Garage Door Opener” to better work with the “doors & locks” module. As far as I know, this would only be useful for the linear GD00Z device (and variants including the Iris opener.) This will allow you to select your garage door device as both the “open/close sensor” and the “garage door opener relay.” At that point, from within the “doors & locks” module, you can use “open and close it remotely” (and perhaps the other sub-modules that open/close the door.) All this does is to add the “relay switch” and “momentary” capabilities to the type, stubs on()/off(), and defines push() to either open or close the door (depending on it’s current state.) It’s not a perfect implementation, as the “doors & locks” module might show the door as being “stopped” wh…

And the Telgard, which is new, and so far most of the people saying that they have one have ties to that company. But certainly worth checking into.

Impressions of Garage Door Control with the Telguard GDC1

Since options are always good, we should also mention the Linear GD00Z, which is also UL listed to the UL325 standard for garage door controllers, has the same features you mention. @garyd9 has a device type for it that a number of community members are using. So just two competing choices with similar features. There are some differences, of course. But any garage door controller which meets the UL325 standard should have the warning before closure and the 2 retries then lockout.
