Cant figure out why the relay isnt opening the garage door.
If I short the Security+ Liftmaster opener on the wall, the door opens OK.
Wired up the Aqara as follows: (and the wall opener works as normal in this configuration to confirm)
I have it set up in home assistant as Dry and Momentary, however it just never opens. Any ideas? I hear the relay firing but the door doesnt open.
You are using the wrong connector ports, the 3 you are plugged into are for physical switch inputs.
you need to use the other side connectors for the relay to pass function to the garage opener.
That did it thanks!
after using this - if the relay is set to OFF, the wall opener stops working. Is that normal/expected and what’s the general protocol? Would it to be set a script up so it always keeps power after triggering?
How have you got it wired for power? you should have either a constant power coming from the garage opener or using a wall socket for power to make sure its always available regardless of state.
The startup behavior should only affect if the relay is in the ON or OFF state when the relay is turned on.
I have a 12v wall socket for power - in home assistant I have the settings as Dry and Momentary
So the only thing you changed was setting relay from ON to OFF and it stopped working? so the solution is to undo that change.
Then how can I get the garage to open if I cant set the relay to on/off?
Sorry this sounds like a stupid question but I’m obviously missing something here then? I only have a switch toggle on Home Assistant. Turning it ON makes the garage door open/close
So am I supposed to write a script so every click always resets it back to “ON”? I.e. its never left in the OFF position?
