Medium Duty Logic MJ5011U not working

Konnected Garage Door Opener
1

Hello-
I have a Liftmaster MJ5011U medium duty logic that I world like to use the Konnected Blaq with. I can’t seem to figure out the wiring. It seems that for my opener to work at all it must have the wired 3 button (Open/Close/Stop) station switch installed. If this switch is not installed the opener won’t work at all with a wireless remote. I tried to connect the blaq to the “open” and “close” terminals on the GDO board but then nothing works.

I tried to install it on the pass-thru method as well but like I said If all wires are not connected to start/stop/close/common wires, nothing functions.

Seems like these commercial openers are really limited on any smart home connections for some reason.

Anyone have any ideas?

Unfortunately I don’t think it will work on this device yet. We haven’t tested or developed a way to interact with these commercial grade LiftMasters, which use a different wireline protocol from the residential garage openers. The blaQ works with openers that use a wired serial protocol to a smart wall button, indicated by a yellow, red or purple learn button – which I don’t think this one has.
