    good thermostat but some improvements needed.

    easy to set up and install. user friendly app is provided for the unit. However, some improvements can be made for trend data. My previous wifi thermostats do provide temperature change historical chart. This help me to judge performance of my heating system while I was traveling overseas during winter season. Sensi thermostat only provides temperature reading at the time when I open the app. I have no way to know the readings one hour ago unless I keep watching it.

  • 3rd Sensi, and would buy again.

    Very good product, without problem. Setup was a little challenging, but their techs helped us get it working on our system. We own 3, at different locations. Would buy a gain.

  • I have been using Sensi ST-55s in three ...

    I have been using Sensi ST-55s in three residential places, two states, and with two internet providers. I have had no problems with this item or its installation. It is a quality product, and I am now using it with two wire condensation boilers without a C-wire.
