Similar issue to a few others I’ve seen where the wall panel needed to be replaced however I believe mine is the version they were replacing them with. I just got a new LiftMaster 87504R-267 garage door opener with the 880LMW wall panel dated 11/2024. The BlaQ is working great with it however the wall panel looses time daily like it is loosing power frequently which I have seen explained as a common issue with ratgdo due to it using some of the power expected by the wall panel. I’m guessing the BlaQ is likely causing it but haven’t disconnected it yet to find out for sure. Just wondering if others are having this issue and if it may cause issues with the wall panel down the line? The BlaQ is at ESP home 2024.10.0 and security+2.0.

Hmm, I haven’t heard this one yet. I would try disconnecting the blaQ for a few days and see if that makes the problem go away. Then we can go from there. Let us know what you find out.
I just unplugged the blaQ and reset the clock on the wall panel, I noticed with the blaQ plugged in the wall panel would make a series of ticking noises every few seconds and with it unplugged it only made one ticking sound every so often like maybe 15 seconds between. I was going to include a video where you can hear the ticking but this site didn’t want to take the file format. I’m guessing the ticking is when data is updating on the wall panel from the garage door opener or when the blaQ is requesting status updates? I’ll watch the time on the wall panel for the next few days to make sure it stays set and let you know. Thanks.
I just plugged the blaQ back in and no time outages during the last few days.
This morning the clock on the wall panel was flashing 12:00 again.
So far it seems to be related to having the blaQ plugged in as the clock on the wall panel stayed working for a few days with the blaQ unplugged but within a few hours of plugging it back in the clock reset again. I’m not too worried about the clock on the panel just want to be sure it won’t cause unexpected behavior with the opener or panel over time.
It sounds like the wall button panel is losing power frequently when the blaQ is hooked up – enough to cause the clock to reset. The way these things “talk” is by pulsing a signal on the power supply line (the red and white wires), and the wall buttons have capacitors inside to smooth out the power. I haven’t heard this problem from anyone else before, so I wonder if the capacitors on your wall button are bad. I think you mentioned it’s a new one, so that’s odd, but it might be worth trying another wall button if you can.
Has anyone else besides @tterk1 had this issue?
I’ve absolutely had this precise issue for months now, @tterk1 and @nate. Unfortunately too many bugs with the BlaQ I’ve not had time to report every little nuisance.
I’m a little tired of fixing the clock. Would love to see a fix for this. It never happened until I installed the BlaQ. I’ve tested with two wall buttons: both exhibit the exact same issue.
System info below:
- Wall buttons: mid-2010s-dated 880LM (bug exhibited); 2024-dated 880MLW (bug exhibited; currently installed)
- BlaQ on Konnected 1.4.0.3; ESPHome 2024.12.2
- Liftmaster Opener w/ Security+2.0
- -52 dBm and 96% Wi-Fi signal
Buying a silly expensive 2024-dated 880LMW also didn’t fix this bug.

That is interesting about the power issues.
I will note also note the wall button is less responsive after installing the BlaQ; previously, it would trigger every push, but now it needs a 2nd push once in a while. I guess I’m catching it when it’s just about dead / not enough power?

Good to know that it’s not a completely isolated issue. Thank you for the detail. We will look into this.

Has a solution to this been found yet? I just got this opener installed with the same wall panel and am seeing the same thing where the clock keeps resetting. I’ve seen it happen a couple of times and it looks like the wall panel loses power.

We’ve tried to reproduce this and find an exact cause but haven’t been able to pin it down. It does appear to be a temporary loss of power to the wall button console that is causing it to lose the time.
These wall buttons and the GDO blaQ (which emulates a wall button) communicate to the garage opener motor over the 12V red/white wires that also feed it power. It does this by sending data packets over those wires, briefly pulling the voltage to ground as it’s sending data. The wall button has capacitors inside to smooth out the power and keep the device powered throughout those momentary voltage drops.
There could be something wrong with the capacitors on some button panels. We’ve only had a small handful of reports of this issue, so it doesn’t seem consistent or widespread.
@Sumi do you have any other buttons or devices on the same circuit? Could you share the date code and exact model number of your wall button?
Thanks,
There isn’t anything else connected, just a straight shot from the opener to the wall button.
the model number and date code printed on the back of the wall button are
880LMW with a date code of 03/25

I recently had this issue again and wanted to check in. 
Mine is a 880LMW with a date code 04/24; I’ve nothing else connected. It’s just the button & opener.
I might be confused, but couldn’t GDO Blaq pull clean + stable 12V from its 12V power adapter? Perhaps a toggle can be added for direct power, vs “borrowing” from the GDO, for those of us experiencing this problem?
I wouldn’t think we are exceptionally heavy users, usually just 2-3x open-close cycles daily. But ideally, that shouldn’t even matter.
The blaQ does not draw power from the garage opener. It only uses those wires for communication. That’s why an external power supply is required to power the blaQ.

All right.
What other options do we have?
With the same problem on two wall buttons, it seems like we’ve spent enough money trying to get the Blaq and button to working reliably.
It’d be helpful for everything to work as intended.
This is not an issue with the blaQ, this is an issue with poorly made wall controls by Chamberlain group (which includes LiftMaster and many others).
The 880LM / LMW are probably the worst affected because they have more going on in them, what with the display and everything, but this seemingly can affect other ones with just a motion sensor as well.
The issue is related to them saving a few cents on a couple of capacitors, which caused issues with them drying out and failing anyway, even for those without something like the blaQ, but the blaQ effectively just highlights the problem.
Someone replaced the capacitors on their 2018 dated wall control panel, with ones that have double the capacity, and seemingly hasn’t had a problem since. Read onwards from here:
I would imagine that user on github was referring to the big black and blue capacitors seen here near the bottom on the sides:
It doesn’t look like it would be too difficult to actually replace them, the problem seems to be that the larger capacity ones tend to be physically larger, and thus fitting the board back in was more difficult.
