Yes, from the feature perspective they are outstanding. We get to control default NO/NC state, power on delay and a whole lot of other nifty features. They are also surprisingly small. It has to be time tested.. but im positive.
On that note,,, im wondering if I should add Emerson Sensi Wifi Smart Thermostat. I am controlling it with some script (becuase its in my house and has an API

), and the HAL work makes it easy to include new driver...but it does not feel right to be included in reef-pi :-/
