#Intermittent operation of garage door using RATGDO v2.5

I have 2 garages with lift master security+ 1.0 openers from the 00s. I installed a RATGDO v2.5 on each one about a year ago following the directions of the RATGDO dev Paul. His directions say that I may need to upgrade the liftmaster wall buttons to 889LM in order for the whole system to function properly, but mine were working without an 889LM so I didn't bother.

Over the last year, the functionality of the remote openers in our cars has deteriorated (for lack of a better term). It started with my jeep. I can almost never operate the garage with the button in my jeep when I first go out to the vehicle. It's unresponsive (even when the jeep is parked directly in front of the door). However once I've been driving the car a bit, the button functions normally for both opening and closing the garage door.

My wife's old Acura rdx seemingly never had any issues with operating the door. But we recently upgraded her to a 2025 kia carnival, and that is now having issues like my jeep.

I decided to upgrade one of the panels to the 889LM per the dev, but this hasn't fixed the issue at all.

As for the network, the RATGDO are wifi devices. I have a dual band mesh network at my home with a node in the master bedroom closet directly above the garage, so signal strength is very strong in the garage and still fairly strong in the driveway too. It's also worth noting that I have 2 additional zigbee- based wall buttons in the garage that are used to control the doors, and those work perfectly fine. The hardwired wall buttons also never present any operational issues. It's just the buttons in the cars that are problematic.

I'm trying to get to the bottom of what could be causing this problem, so I'm hoping someone here has some guidance to help me. I can't find any way to contact the dev for tech support on his device, so I have to rely on the home assistant community for support.

they just talk directly with your garage door unit

#

if those are flaky, your garage door unit is likely the cause

You can confirm this by simply unplugging the ratgdo from the wall

#

Unplug the ratgdo from the garage door opener and unplug the ratgdo

#

If your remotes still behave the same way, that's even more evidence that it's your garage door opener.

I suspect there's some kind of signal issue caused by the ratgdo. When I installed the 889lm this weekend the garage door started operating erratically - opening and closing partially and fully every few minutes for like 30min straight until i stopped it. This behavior only stopped once i unplugged the ratgdo, so clearly the ratgdo was somehow scrambling signals or sending erroneous signals. I plugged the ratgdo back in after that and the erratic behavior didn't come back, so I assume it was a one off issue with the device.

Well, you have to confirm that it's causing signal issues before you assume that's the case

#

That's a recipe for going down the wrong path and wasting time

#

I think i did that already

#

I unplugged the ratgdo and it stopped

glacial yacht
#

"it stopped" meaning your remotes work again?

#

That's what you are checking here

#

I meant the erratic opening and closing stopped. That's a different issue from the car remotes

glacial yacht
#

Right, we are trying to solve the car remotes

#

so, to make sure the car remotes still work properly, you need to remove the ratgdo from the equation

I also have this issue on the other garage door, we just don't open that one as often since I don't park in that bay

glacial yacht
#

it's still good to know that ratgdo is the problem or not

#

I've been working in the automation industry for many years, what can happen will happen

#

especially with old tech

#

Yes, it's unlikely but you should rule that out first

#

then if they come back to life, it's time to start reviewing your wiring diagram and ratgdo configuration
