Tuxedo Touch is very interesting automation controller that works with First Alert security panel.
watch youtube on this Tuxedo Touch. youtube - search "tuxedo touch". It is actually a very easy to use automation controller with built-in zwave controller that can do a lot of zwave devices like lights, locks, thermostats and shades. this thing can connect to IP cameras to see live video feeds. the best thing is it has a built-in web server that can turn any device with a web broswer such as smartphones, iPads, tablets, pcs, laptops and smart tv to control the system. don't have to down any apps. if you know how to open up ports in your router, you can remote control everything.
Tuxedo is not a thermostat. it can control the Honeywell zwave thermostat. you can add a second zwave thermostat for your sunroom.
hope this helps. you can google tuxedotouchtoolkit site for more info
