Neither of mine pair. The instruction say once connected to power they should begin pairing and show they are pairing by the flashing white led. This never happens. I may have to open the seal on my Wink Hub I got in July to see if they will pair there.
I would think there would be a way to start the pairing process but I haven’t figured it out.
If no, look at the PEQ thermostat from BestBuy ay $129 which is a centralite and cross reference it against the ST supported devices list. Also there are several 2GIG devices not he ST supported Devices list that are at a lower price point.
