I really hope you have better success than I did with the Trane. A lot of people have success.
However, my two BB32 thermostats have been terrible on the zwave side. They work fine as thermostats, however I have been having serious problems on the control side with both of my thermostats falling off the network within a couple of days and requiring a reboot.
I can handle bugs sometimes. However, Trane's support is completely non-existent. If you can find their support number and eventually call, the very friendly but non-helpful support representative cheerfully refers you to a Trane dealer that "can support and fix the firmware" .. When you call a dealer, they expect you to authorize an expensive service call to look at your thermostat for warranty support.
I will eventually just move to the Nest. It is more expensive, Wifi only, and the plugin is a bit of a hack. However, even if Vera support eventually fails because they change their API, I still end up a with a great device, good community, and a high WAF for the home. I may lose the zwave repeater functionality, but I can work around it with other devices.
