Help with Blaq with Liftmaster 98022

Konnected Garage Door Opener
1

As the title says, have a new Blaq with a new (2026) LM 98022 opener, 880LMW wall panel, and I can NOT get this thing to work with the opener. I’ve read through every other relevant post, and I seem to have some combination of ALL of the problem. Wall panel loses time/connectivity regularly. The blaq is alive, responds correctly, but doesn’t actually communicate well, or at all. Sometimes, it can open/close the opener, but rarely. Some of the status is correct - sometimes. Basically the answer to everything is “sometimes”. Sometimes it will, sometimes it won’t do (whatever). And when it does one thing, that doesn’t mean that it will do anything else. Example, it MIGHT open/close the door, but it will probably show the wrong status of the door, the motor, light, etc. But, maybe not. It may show the correct status, but won’t move the door.

I’ve factory reset it several times. Loaded the latest of everything I can find (ESP version 2026.1.3, project 1.5.7.2). Tried it on my other, absolutely identical opener, same thing. Rebooted the opener and the Blaq - including removing the backup battery, no change.

Removed wall panel, only using the Blaq, no change. It will sometimes say it’s synced when I choose “auto”, and when it does this, it’ll sometimes do some things correctly. But rarely. But sometimes it’ll keep trying to sync for days, but won’t. Then if I set it to 2.0, it’ll sync….and sometimes do some things. Sometimes it’ll “sync” to 1.0 w/ smart wall panel, but if it autos to that or if I set it manually, it’ll say it’s synced, but it won’t do anything at all then.

I have an old RatGDO that actually works perfectly fine with it’s opener, and both of these new ones. Syncs right up automatically - didn’t have to do anything other than wire it up and turn it on!

I’m at a complete loss. This thing seems to have lost its mind. ANY help would be greatly appreciated. I can’t imagine anything that I haven’t tried without the exact same result. IE, “sometimes”.

Update. Disconnected the wall panel. Factory reset the blaq, loaded latest proj and fw. With the wall panel disconnected, SEEMS to work correctly. Going to test for a bit, re-connect the wall panel and see what happens.

Well, I’m stumped. Blaq kept working without the wall panel, so I decided to try hooking the wall panel up passthrough, what could it hurt, right? I did, wall panel started working, but blaq went back to working - stomtimes. Then I cycled power to the blaq….and now everything works correctly. I have no idea why any of that did, or should have worked.

@Bryan_Baker sorry for the frustration, not sure what exactly the problem was initially.
This is definitely a Security+2.0 opener, so that should be the protocol setting. And it should work perfectly with this opener.

If it seems to get out of sync again, try hitting the re-sync button on the web UI. This forces the motor to re-sync with the blaQ and can fix any “collisions” with the wall button.

Thanks @nate I did attempt the re-sync button on the UI to no avail. In fact I tried every way conceiveable to re-sync, restart, you name it. Little update, I went back and re-weired the Blaq the way it was originally with just a parallel connection at the opener itself, and it went back to the same behavior of just sometimes working, kinda. Put it back into the passhrough configuration, works flawlessly. I don’t get it, unless there is something inside the Blaq other than simply a trace connection between the passthrough terminals that affect the electrical properties (resistors, etc)?

There’s really no electrical difference between pass-thru and parallel connection. The pass-thru red and white terminals are electrically connected to the other red and white terminals so it’s really no difference at all at the electrical connection.

Sometimes those push-in terminals on the back of the motor can be tricky to get two wires in cleanly, so the only thing I would suspect is that it’s a loose connection on the parallel connection. Try twisting the wires together, make sure they’re stripped evenly and secure in the holes.

Let me be clear, I’m not here complaining or arguing, so please don’t take anything I say as a gripe. I’m simply sharing some feedback on what I’ve observed to help the community and developers alike. “If it ain’t broke, or I don’t know it’s broke, I can’t fix it!”. Not suggesting it’s broke, maybe the broken part is me! LOL Statistically speaking…it probably is me LOL.

Regardless, I was concerned about those terminals as well. I know people shove 4 wires in there all the time and it “works fine”, and it probably does, but this isn’t a relay or an incandescent light we are talking about here. Slightly more sensitive to stable and sufficient terminations.

So, I tested it out. I took a single set of leads from the opener to a set of wire nuts. Pre-twisted the leads from the opener, the wall pad, and the Blaq together and nutted them. Just so I’m being clear, ONE set of leads from the opener, the Blaq, and the wall pad, all 3 twisted together and nutted, so the Blaq is technically in parallel - no passthru.

Still no dice. Sometimes, kinda works. Rarely figures out the security+ setting on it’s own, if ever. Wondering if it’s the main terminals on the Blaq, I moved the leads going to the Blaq over to the passthru terminals. IE, nothing on the main terminals, just a set from the passthru going to the wire nuts along with the leads from the opener and wall pad. Same result, still didn’t work correctly.

Now, because this made me even more curious, I kept the single set of leads from the opener and ran it to the Blaq, landed them on the main (non-passthru) terminals, and ALSO landed the wires from the wall panel on the main Blaq terminals. So I made the parallel connection at the Blaq, not the opener. For reference, my Blaq is probably 8” away from the opener.

Still parallel, nothing on the passthru terminals, still same result. Kinda/sorta works sometimes. Moved both sets of leads over to the passthru terminals, leaving the main empty, same result.

In that same configuration, removed just the wall pad. So Blaq is directly connected to the opener via the passthru terminals. Immediately begins working perfectly.

Then, re-connected the wall pad to the passthru terminals on the Blaq, moved the opener to the main terminals on the Blaq so it’s back in it’s “correct” passthru configuration. Boom, works immediatley, and perfectly.

I’m at a loss still. The ONLY way I can get the Blaq to work along with the wall pad is to wire the wall pad in the passthru configuration. The only thing I can think of right now that I haven’t tried, which I may go do, is to wire it in passthru “backwards”. IE, the opener to the passthru terminals and the wall pad to the main terminals on the Blaq. Should this make a difference? Absolutely not. But, nothing else has so far either.
