Works perfect for the two busiest stats in our building. It lets us get better management over our heating and A/C expenses because building users are not always attentive to adjusting thermostat to cost saving settings when finished the room!
Home comfort installed and helped me get it on line. It did take several work arounds on their part but work great now. Hoping for savings and when I'm away not wasting the energy.
So far I am enjoying being able to control our church thermostats from my phone. I no longer have to travel to the church to adjust the temperature in the sanctuary or classrooms.
Overall happy but would like to see better system issue notifications - above and beyond temperature alerts - some thing that would identify issues with the Heat Pump when it is not working properly. Those issues could then be communicated in the app.
