I replied to another topic with an initial question related to difficulties I have had with getting the Iris CT101 thermostat I picked up on Amazon.
But now feel this is due for a separate topic.
I did actually manage to get my thermostat paired once. I tested it out using the SmartThings provided CT100 device handler. All worked good except I did not have C wire connected for that pairing process so it didn’t get paired using the desired Zwave mode…
The pairing process I took was insane and no idea what actually made it work except that at one point halfway through factory resetting the thermostat Smartthings in “add a thing” mode finally found it…
All worked but as I said it was in battery saver “beam” mode… So I removed the device from Smartthings and did the exclusion process as well. Rewired it to use the C wire and ran into same issues getting it paired.
After several Zwave repair marathons I finally noticed something in the logs. Each time I tried to Link the thermostat to smartthings the thermostat would say it linked but smartthings never saw it. But later when I did a zwave repair, I noticed in the event logs it would find an orphaned device (id 43 the first time) I got rid of it and tried to pair again. No good. Another orphaned device (id 44 this time.). Repeated the remove/exclude/pair process again (id 45 now.). But this time instead of removing the orphaned process I created a device in the IDE and gave it id 45 with the ct100 device handler.). This worked for the most part and I could control the thermostat and get data back but I never got the proper zwave raw data in the device info page on IDE and each time I tried a zwave repair it always reported that that device couldn’t update the mesh (I tried about 5 times to repair …)
Any thoughts on how to get this thing to pair properly???
I’ve got a radiant heat setup with a thermostat in every room. The high cost of simple zwave thermostat has prevented me from pursuing it but these CT101 thermostats are actually affordable now! I would like to replace more but not if this is the nightmare I face each time I want to add one.
