I have three Iris garage door openers. Earlier this week one of them stopped working for no explainable reason. After repairing the Z wave network and still not being able to communicate with the device I removed it from the hub forceably.
I then excluded the device from the hub in the Z-Wave settings.
I then went to add the device back. When I did the device was discovered and got stuck on initializing. So I repeated the actions above. Now I am on the third attempt and as you can see from the screenshot all three devices are initializing but none of them work.
This is a secure Z-Wave device.
It is my opinion there is something going on with the hubs... I’ve posted my experience and I’ve seen many others... Lots of people stuck at initializing... If you read my thread about perpetual initializing, I wrote about a way I was able to get devices to finish adding... Maybe try that...
Basically it’s a restart of the 60 second clock seems to force the final push to finish... Worked for me about 90% of the time...
Do you have your hub near by, the garage door opener is a secure connection device so it requires close proximity during the pairing process? I've seen Z-Wave device stuck like that before most of the time a few tries got them working but I had one device I had to try many times like 20 before it finally connected and the last 5 tries were within feet of the hub. You may also want to try rebooting the hub to see if that helps at all.
Once you do get them working again if one stops responding I have always been able to get the Linear/GoControl garage door controller working again by unplugging it, plugging it back in after a few seconds, and hitting the pair button on top, within an hour it has always worked again. I've had to do this process once since adding it to Hubitat and many times in the past with Iris and SmartThings hubs.
I live in a Faraday cage (steel siding) with a detached garage and was able to pair my GoContol GDO in place, 2 hops from the HE hub (first go as well). If you have a well established mesh, there should be no problem pairing in place.
