Linear GD00Z-4 Initial Install Problems - Need Help
« on: April 12, 2017, 10:11:34 pm »
I purchased a Linear garage door opener GD00Z-4 (it says Linear on the unit itself).  I followed the directions perfectly, but after it pairs with my Vera Plus, it shows that the door is open all the time, even though physically it is shut.  If I manually open the garage door, then close it, it still shows open.  If you try to 'close' the opener from within Vera, it says 'Sending Command' and then 'Success/Transmit OK',  however it never actually switches positions from open to closed in the Vera devices area.  The Linear unit itself doesn't flash or beep at all either when you try to activate it from Vera.

I tried a new battery on the tilt sensor - same issue. 
I am able to un-pair, and re-pair the garage controller from the garage, so I know it is able to communicate with my Vera Plus.  It says 'Sucessfully Exchanged Security Keys' and everything.  I even tried moving it inside to within 10 feet of the Vera Plus but exact same thing (brought the tilt sensor in also). 

I'm thinking maybe a defective unit out of the box??  Any ideas?

Possibly defective.  The fist one i bought was.  Just like yours, it paired but didn't respond to Vera.  Thank goodness for Amazon's return policy.  The sensor communicates with the module, not with Vera; so if the module is bad, the sensor will be out of whack as well.

Hi there,


I suspect the tilt sensor might be at fault or maybe not positioned correctly ?  As status of the door is basically given by this sensor.
Especially if you don't get any configuration errors, and you mention it says Transmit was ok, when doing any commands. So the communication between GDZ and Vera looks good as well. To confirm this, you can go to Settings of the GDZ -> Advanced-> Commands -> and Stress test : Give it a few seconds, if the response output is good, then the issue would be the GDZ itself.


I would verify this with Linear support as well.

I think I have a similar situation with an older (existing installation) GD00Z.  Is there a source for replacement tilt sensors?  How is the sensor paired to the GD00Z? My research makes me think that they use 345MHz signals, but how sophisticated is it? Are they interchangeable?

Thanks for all the replies.  I ended up getting a return authorization and shipping it back for a replacement unit.  During that process, I noticed the box showed GD00Z-5.  Not that that matters, just an observation.  Hopefully the replacement unit works better.  Thanks!
