LiftMaster

Q: Is this compatible with my q?

It USED to be compatible with MyQ. I had it configured for the last two years, working fine, and hooked up to Amazon Key for garage deliveries. Today, for unrelated security reasons, we had to reset all the remote codes on the 850LM and re-add them. Now the MyQ app will NO LONGER allow you to pair with the 850LM. It is not a technical limitation, it is a product marketing decision. I suspect they want to force people to shell out hundreds of dollars to upgrade their whole garage door system if they want internet access. It's a very lame decision by liftmaster to break something that was ALREADY WORKING.

Q: Will this work on a power garage door with no remote, only interior push-buttons?

It's basically a set of buttons that can be remotely activated. Supports up to 3 buttons to control up to three 1-button openers or one 3-button opener. Supports both NC and NO type on channel 3 for stop buttons. Remote not included, just get a new liftmaster 3 button and it will work. I went with a 4-button remote, I control the 3 channels of this receiver for my shed and the 1 button opener on my attached garage with 1 remote.

Q: Will this work with liftmaster 855lm homelink repeater? learn via yellow button on 850lm.

Yes it will, I just did it. You may have to press the Homelink button in your car a few times before the 850LM learns it. That's what I had to do.
