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.
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.
Aquired a property with multiple garage door openers. Two work with blaQ; the other two are LiftMaster Commercial that use the Logic 5.0 board / Security+ 2.0 / myQ with the 3 button (Up/Open, Down/Close, Stop) Wall Controller. It sounds like this setup isn’t supported yet by Konnected.
@nate As the Konnected founder, do you forsee a solution in the future? And if so, do you anticipate it working with blaQ? Ultimately I’m just wondering if I should return the two blaQ’s I bought for the commercial ones, or hang on to them to potentially use them in the future.
Ideally, yes I would like to be able to support all types of openers ultimately, but for now we’re focused on the residential grade devices. The commercial grade LiftMaster openers seem to operate quite differently and we haven’t yet spent much R&D time trying to figure them out. I don’t have one at my disposal to experiment with at the moment, and it’s not actively on our roadmap.
One thing I’ve observed about these commercial openers is that they all appear to have dry-contact inputs for open/close/stop triggers. So, that would imply that it should be pretty easy to automate with relays… but this is not how the blaQ works.
The blaQ works by emulating one of the Chamberlain/LiftMaster digital wall buttons, which aren’t compatible with the commercial grade openers.
It’s unknown to me at this time if the commercial devices use a similar digital wireline protocol as the residential openers. Maybe they do, but the commands are slightly different. If that’s the case, it may be possible for the blaQ to communicate with it, once we are able to reverse engineer the data protocol.
Honestly, I would recommend that you return them before the 60-day return window. You can always repurchase again if we upgrade them in the future.
If anyone has a spare commercial opener or logic board that they want to donate or loan out for R&D, let me know!
