New to SmartThings products. I have two Lowe’s/Iris Version of CT101 thermostats. Both are installed and working. They’re both running off AA batteries as I have only a two-wire system for heat only from an oil boiler - no C wire option.
I have V2 of the SmartThings hub and have successfully paired an outlet and a couple of motion sensors to it, but can’t get either of the CT101 thermostats to pair with the hub. I have tried 1) putting the hub literally next to the stat during the pairing process, 2) factory resets of both the hub and each stat, and 3) attempted Z-wave exclusion of the stats from the hub via the SmartThings app. For both stats, the word “LINK” does not appear under the radio icon of either.
I believe I’m successfully setting the thermostats to be discoverable, with R1 displayed on-screen of the stats and the word “MATE” flashing while the hub searches for devices to add. Not sure if it’s because I’m on batteries with the stats, but the time the stats appear discoverable (blinking MATE) seems short-lived before it defaults back to the home screen. So I’ve also tried keeping the mating active by pushing MATE on the stat to try and keep it from timing out.
What are some other things I can try? A different brand hub? Is there an alternate app I can use to try and pair the stats to the ST hub? In the short-term, I don’t have the option of adding a C wire or other power source.
