yes still no issues after installing the ups
one of the watch batteries died on one of my door sensors (to be expected) just replaced the battery.
I have 2 garage doors both setup exactly the same.
Do you still have issues when using a UPS battery backup?
Got the same problem. I did buy another one and it does same thing. Donāt know what to do now
If using a battery backup on the device didnāt help have you tried
excluding the zwave device (GD00Z) and then adding it again (once you have
the battery backup installed)?
highly unlikely 2 different GD00Z are having the same faulty problem
must be an issue in the SmartThings setup.
I wanted to followup on this thread as Iāve been battling an on-going issue with my Garage doors thinking they are opening and actually not all on theyāre own. Smartthings support was stumped and couldnāt see anything that triggered it behind the scenes but can see where it happened. for me it primarily happens on 1 of the 2 doors so that was the test case for my voltage stabilizer. I have used DROK Dc-Dc boost converters in the past with great results and so it was my go-to for this test. I have to hand it to Linear they put a pretty solid clean power supply in the box. using my vohm and I wired in the stock 12V power supply into the boost converter both read a solid 12V out to 2 decimal places and held it. The other one I tested for my Netgear router (same size plug) would fluctuate from 11.9-12.1 over time. So I tuned the DROK down as low as possible without essentially unregulated it so I dialed into 12.1 output. It hangs in the open easily visible from almost anywhere in the garage and was always at 12.1 when I looked at it.
Fast forward a few weeks and it was rock solid with no falseās until the beginning of this week when like usual it triggered in the middle of the night and got stuck in this opening mode. power cycling fixes it like usual but apparently a voltage drop was not the problem. Iām back to the drawing board on this and Iām not really sure where to go beyond a whole new route in opener as both doors have this issue but one occurs 4-5x more often than the other but it affects both of them.
I wanted to just post my findings for anyone else battling the same issue and thinking of going this route. I may end up putting the Power supply on a switch and set it to power cycle once a week just to clear out the GD00Zās ācobwebsā.
Not familiar with the drok converter but it does not appear to have a battery backup so if there were any brown outs voltage would drop.
The UPS battery backups I use are just the basic office/computer battery backup from Costco
I have installed a smart outlet on the GD00Z, which I power cycle once per week. Itās been several months now and no issues with false openings yet.

I am also seeing the false āopeningā state. I have replaced the battery and power cycled - but am still seeing the problem.
Not sure how often yours is doing it but I think the only solution for now is similar to what @Kevin_Rzemien is doing. I think power cycling the unit (either manually or via a smart outlet)every now and then is probably the way to go. I really donāt know if the issue lies in a faulty device or if itās a faulty device handler. The problem is so random and sporadic itās really hard to tell. Iām leaning towards device handler since when it trips on itās own for me it tends to be very cyclical. For me when it starts if I donāt reset the unit and let it go it does it liker every 4 hours to the minute or every hour to the minute continuously.
For now I just have to keep the garage door opening out of my alarm triggers and Iāve added extra motion sensors in the garage to trip the alarm.

Hello,
So, my opener has ceased working, like many of you have run into. Iām guessing, without having put a voltmeter on it, that the control board maybe having an issue. I see the commands issued in the SmartThings log, and the opener signals itās alert like itās going to toggle the state, andā¦nothing. Iāve power cycled the thing, and replaced the orientation sensor battery. I have yet to go through the re-pair steps, but Iām not hopeful that would accomplish anything. Thoughts on that?
Thanks!
iāve read somewhere that the problem could be wireless interference. i have the same problem and it seemed to happen a few months ago. i replaced the battery after having problems. i thought it was fixed but i have the problem (says open when really closed) intermittently.
Mine worked well over the last year then today they started getting the notification "the door wont open or closeā even though no remote was triggered.
Random thought: Are any of you who are seeing this issue using an LED bulb in the garage opener light? I know LED blubs can create havoc with the opener failing to respond to the remoteās RF due to noise/interference caused by the LED bulb driver. Seems unlikely butā¦
Anyone had any time to take a look inside the GD00Z-4 unit? after 18 months of normal use, I now have the same problem. The tilt sensor is fine (even tried with a new battery) and shows open/closed when I use a remote or the on-wall switch. So, my guess is that a relay (?) in the unit doesnāt trigger to close the switch for the door. The beeps let me thing that the unit gets the correct command (but I could be mistakenā¦), so thatās why Iām suspicious of a failed relay (or something like it) inside the unitā¦ Iāve just sent an email to their support email. Iāll try to get the unit down and open itā¦ Power cycling didnāt do anything different. Havenāt tried the remove/add to ST. Since everything shows to be āokā on the communication/report from the tilt sensor too.

I have similar issue as thanos66 stated. After working around 14 months, the unit the GD00Z-4 stopped working. I called technical support and they suspected the faulty relay. Warranty valid for 1 year only. Tech support did not accept my request for warranty replacement. This is god looking device (but not a good design). I opened the unit and found the relay, driver transistor are okay, issue is that no signal is coming out from the programmed IC.
So, instead of trashing the unit, I am thinking to resolve my issue with different ways.
The relay (inside the unit) is not getting turn-on signal from the programmed IC. Both Green and Red warning flashing LEDs are not working. Only, I am hearing 5 seconds warning beeps when pressing the open or close button in the ST apps . Soo, I am thinking to design a delay switch which will activate a relay if beeping occurred for more than 4 sec. This way I can avoid false or short beeps. Then the relay will operate for 1 second to turn the door opener. For my case, I think firmware corrupted.

Hi Thanos66, did you ever get this resolved? I just started to have the exact same behavior after about 18 months.
Hi Matthew,
unfortunately I didnāt resolve it. It seems that the unit gets the command to open/close but the relay is not doing its job, either because: the relay has failed or it doesnāt get the command anyway.
whatever the reason, I decided to do a workaround by using a relay that SmartThings can use as a momentary switch (exactly whatās needed). The relay I used is: https://www.amazon.com/gp/product/B00ER6MH22/
Check the two top reviews for that product in order to add it as a āmomentary switchā for the garage door use.
The cables (the blue ones) are easier to use when using Heat Shrink Wire Connector (terminal connectors: fork, hook etc.). That way, youāll be able to insert/remove any cable from the wire terminals of the garage unit.
Funny enough, this relay is from the same vendorā¦ āGoControlāā¦ I hope it lasts more than the GD00Z-4.
If you have any Qs or encounter any problems, let me know and hopefully I can help 
I have installed it and use it for a month and it works flawlessly. It doesnāt have the flash light/sound and delay for the open/close of the door but then again, Iām ok with that. For the status of the door (open or closed) I use a SmartThings multi-sensor as a garage door position indicator (otherwise you do not know if you opened or closed the door, itās the same for the relay).
In hope that someone has more electronics knowledge to figure out if itās just a relay failure or the micro controller on the GD00Z-4 unit. So so disappointed with that.
According to this ST threat, it looks like the LED is degrading and not allowing the signal to cross - appears to be a safety threshold to have both the audio and visual warnings before the relay switch. Since the LED degrades quickly (1-2 years) it blocks the relay from receiving the signal. Everyone who has soldiered on a new LED or 3 - 10 ohm 1 watt resistors in parallel have reporting success.
Good Evening :
Sorry for late response. Actually, I was out of Smartthings for last few months due to my job related issues. Now, I am back.
The problem was resolved.
What I did:
I added a ESP8266 powered by 5V from cell phone charger, which count the beeps of the door opener. Before that I measured the on-off duration of the each beep with another ESP8266 circuit and then counts the total beeps in 5 seconds through an opto-iolater connected to the buzzer. So that no other signal or noise can trigger the opener.
When the count of the beep is more than >22, then one of the port of the ESP8266 will trigger another opto isolator , that will turn on the original relay of the door opener.
Since November 2018, door opener is working well.
If you need detailed with circuit diagram and code, please let me know your email address, I will send you. If you need to talk me, please let me know. I can help.
Again, I am sorry for being late.

Thanks to John_Chrouch above, I also repaired my GoControl GD00Z-4 by soldering two 4.7 Ohm resistors in parallel across the indicator LED (not the big one that blinks when syncing, the small surface mount one that blinks when attempting to open). Thank you! I believe the story that the LED was fading and that made the device believe the visual cue wasnāt being given so it would fail to operate the door.
