My new Trane HVAC system came with XL 824 thermostats. I would love to control them with my ST Hub, but, that is simply not going to happen (as far as I can tell noone has hacked them and they only work via Nexia’s home automation offering).
The news that does not suck (it’s relative), is that as long as I do not add any other zwave devices to my Nexia account, I can control all of my thermostats for free (read the fine print on the back of the 2x3 Nexia setup card that comes with your thermostat). And, I have not intentions of adding anything to that account that would cause them to start charging me $10/month.
Also, their iPhone app is not horrible…
