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.
