Got a new garage door opener installed a few months ago and didn't think about HA but it looks easy. There is a connection on the motor which is just a momentary switch (relay) it seems that closing the circuit briefly causes the door to change state (open or close).
There are also radio controlled remotes of course.
I have both GH and Alexa and would like to be able to control the door from either. I also run HABridge on a Pi3. I am guessing some sort of Zwave relay would do the job but I would then have to invest in a Zwave bridge I presume? That could be attached to a PC or maybe the PI?
Any ideas of the most cost effective way of doing this? I am not worried about outsiders being able to access the door since my Dots and GH cannot hear any command from outside no matter how hard you shout!
