hot water baseboards upstairs

Sorry for being a little off topic. You mentioned hot water baseboard upstairs. May I ask which thermostat are you using for that? I am desperately looking to replace a freaking White Rodgers. Picture in this thread:

Need help with ST supported thermostat with no C wire

@Smart, If your usage is with baseboard heating only (120/240V), the only thermostat out-there that can be remotely controlled for that usage is the following: https://casaconnect.com/ This is a new device in pre-order now. They are supposed to publish their APIs in 2015. As soon as their APIs are published, I can work on integrating it to ST just like I did with the ecobee thermostat. See the following links about the work I’ve done for the ecobee thermostat. Regards
