I measured the voltage at the wall mounted garage door switch (which has 3 buttons, open/close, light and lock) it has 1 wire going in and 1 wire going out, the voltage is a constant 24v when I press the button the voltage drops to about 3v and that signals the door opener to operate.
My first thought was to use a smart outlet wired to a 120v relay and have the wire that runs from the wall mounted switch go through the relay, that way the relay would cut the power to the signal going to the door opener. But that didn’t work.
Is this typical of all garage doors? How are people using a smart outlet and a relay to signal the door opener?
And how does the gocontrol gdz000 work any differently than a relay? I am obviously not understanding something and I don’t want to buy 2 gdz000’s if that isn’t going to work.
My garage door opener is a chamberlain lift master model # 41AB050-2
