Hello. I just purchased one of these Thermostats from Smarthome. The product title says that it is ZigBee Enabled. However when we received it I can find no mention of ZigBee in the manual or specs. I tried to call the supplier that is listed on the Smarthome webpage however it is listed incorrectly.
It's always a good idea to read the manuals *before* purchasing to ensure they fit your needs--unlike a lot of online stores, Smarthome offers the manuals for most of their products right on their product pages.
