I am integrating MyQ garage doors with an access control system. Two wire communication (not simpl relay) controllers are in use.

I have been using the hack or soldering two small leads to the circuit board button since there is no relay input available. This connects to a normally open relay on the access controller. I have done this many times sucessfully.

I have one door that not only open on its own occassionally but also intermittently acts as if there is a pressure error when the native controller is used. I have tried two different controllers (both with my soldered leads) and have seen the same behavior with both native controllers.

On this property next door, I also have two doors that occassionally activate on their own.

We have had the doors services by the installer all "seems" good from their perspective.

Wondering if anyone has any experiences related to any part of the issues described above. Diagnosis as been frustrating.

Thanks!

I just installed a myQ Chamberlain Smart Garage Control - Wireless Garage Hub and Sensor a month ago and like it so far. I guess you are trying to integrate a third party control system that is not MyQ? I'm not sure I understand what you have going on but if there is a garage door pressure issue with door closure that's adjusted by the programming of the garage door unit itself right, nothing to do with MyQ?

Update...

Garage door company switched opener to motor wires (conductors) and the pressure error issue went away (so far that is). There may have been a shorted or damaged wire.

If that does solve that issue then the remaining issue is door opening by themselves.

The door company is blaming me because, of course, soldering wires onto the circuit board of the opener voids the warranty and is non standard.

Given that my two soldered wires are an normally open contact, the only way I could see that would cause issue is if the solder spilled out onto a conductive part of the board or if I had too much exposed copper exposed to a conductive part of the board. I do not believe I have ither of these going on.

Also for clariy, there are two circuit board mounted push button switches wired in parallel that are engaged by the opener button. I am soldering to the mounting points of one of these buttons in order for my access control system to mimick the closure of the button.

Consider the possibility of noise pickup on your wires. Shielding or a capacitor may help.

What's the control system?

Had this happen on 2 different clients in 2 different neighborhoods.

Short version of the story is the MyQ people think when we were setting up the doors a nearby neighbor opened or closed their door that was on the same frequency. We deleted the doors out of MyQ, factory defaulted everything and setup again. Has not been a problem since.

Rather than soldering onto the motor board, you can try one of these

^^^ Nice! Thanks for mentioning that.

Ha! I was working at a customer site and noticed that the garage doors kept opening or closing at odd times while I was on site. This was a large, multi-unit project by a national chain. Turns out that the garage door installers were simply using the defaults for each garage door installation.

It's like when a client tells you they will give you the garage door code, and then tell you its 1234

I need to do some research. I thought that garage openers used 'rolling' codes so that type of thing couldn't happen anymore, even at default codes. Interesting.

You can take a remote and solder two wires, or use what golden posted, then attach that to a Shelly 1 relay and have control. its cheap, brilliant little wireless relay. Ive done it with URC TC.

Further update...

After bypassing the in-wall wiring and a few other troubleshooting steps, the issue is still happening. I do not think it has anything to do with my soldered wires on the board but of course, since this is a modification, the garage door company wants to blame it on me :). The builder has requested that they replace the motor head and/or examine the sensor wiring. It seems a bit far fetched that any signeal introduced by a simple relat soldered to the button would cause some sort of door pressure error.

They do- IIRC, all garage doors use 'code hopping' to prevent others being able to open a door. However, if you check into the ways the sneaky bastiges watch and wait with their code sniffers, it's not hard for them to get in. Also, unless the place has cameras, it's not difficult to open a door if the red pull cord is still hanging from the release- If you want to know how, PM me. Once they get in,m they can teach the opener the codes for their opener.

OK, you bypassed the wiring, but did you remove anything you added from the opener?
