  • Great, but could use more smarts
I got this because I have a line voltage heating system, and wanted something that would be able to be a bit smarter than a timer. This thermostat works well, but has a few flaws: The only default option to control the temperature in any kind of smart way is to have it keep track of your location, and turn on the heat when you're in the vicinity of the home. However, theres other times you want to lower the temperature or turn it up, for instance, when I go to bed, I want to lower the temperature, and when I wake up, I'd like the house to already be warm. There's no default integration with Google Home. Luckily though the thermostat works well with IFTTT, and I created commands that allow me to tell Google home to change the temperature. I was also able to use IFTTT to set up rules to change the temperature based on the time of day (for when I sleep). Also, and this could be the issue of the phones, but I have an android and my wife has an iPhone, but sometimes we'll be home, but it hasn't recognized that we're there yet and still shows the mode is in away. I wish it could integrate with our other Nest products or Google products to help determine whether we're home. ... show more

  • Fine Thermostats
Setup is very easy, and connecting additional thermostats to the controller is also straightforward. The geofencing feature is pretty hit or miss, and misses often enough that I just use a programmed schedule rather than relying on geofencing. My biggest problem with these is that the ambient temperature they display isn't the real ambient temperature. They measure the temp, then use some internal algorithm to approximate the temperature in the middle of the room. In my case, the approximated temperature is a few degrees higher than the actual (measured with a thermometer). Thats easy enough to plan around, its just frustrating that the temp displayed isn't the real temp. I asked stelpro tech support to see if there was a way to turn that feature off but was told no. For a positive, the energy tracking feature is awesome, and is a lot of help in understanding my energy bill. ... show more

  • Best you can hope for in inductive heating
Overall, this is a good thermostat for inductive heating situations. It isn't as good as a Nest and the geofencing features are hit or miss, which is kinda critical to the usage and the energy savings that you should be able to realize with a thermostat with this. The display is a sort of low resolution and doesn't have all of the information that you would want on it. It has the current temperature, the outside temp and the humidity, but doesn't have the set point. In fact, it is annoying how hard it is to change what the set point for a thermostat is. My install was a bit more involved than one normally would have since I decided to slave a second heating circuit to the thermostat using a relay. However, that works well. One thing to note is that this thermostat will rapidly turn your heating on and off to simulate different heating levels. ... show more

  • 15 Month Report - Need Replacement
It has been great to be able to manage and control my wall convection heaters. The programming capabilities and connectivity options have been great. After 15 months, it started going on the "fritz." Once it reaches set pt temp, it would shut off and on rapidly. It's almost like something internal had stopped working. Even so, I still like it and will probably get a replacement. ... show more

  • Not very smart without app
I installed one of these controllers along with the white satellite thermostat. They connect to each other directly with zigbee radio and I can set the temperature for both at this controller but that's it. There's NO TIMED PROGRAMMING or any way to set a schedule on the unit itself, degrees like a big gap in functionality and I would but have paid such a premium had I known this wasn't a feature! ... show more

  • Frequently locks up, tech support non-responsive
I purchased this and the auxiliary unit to control base board heaters. The first problem I noticed is that the weather for my house (based on location) was not accurate at all. The auxiliary unit had trouble keeping sync with this base unit. After three months this unit started to lock up and became unresponsive. Sometimes this would happen when the heat was called at 100%. The lock up prevented the thermostat from lowering the temperature at night. We would wake up to a sauna! The only way to reset this unit is to turn it off at the breaker. This unit continues to lock up and requires a circuit breaker reset every three or four days. I called tech support and got no answer. I also sent multiple emails to stelpro and received no answer. I expect so much better service from a Canadian company! I cannot continue to risk leaving a runaway thermostat in service and have replaced it with another brand which is 100% reliable (although very basic). I like the features and the programming of this unit but have found it completely unreliable and causing waste by running excessive heat outside of schedule. I highly recommend that you avoid this unit and the auxiliary units. ... show more

  • Good luck and godspeed
This is a broken product. It works great when it wants to, but it consistently gets locked up. The screen stays black and Stelpro support describes it as thermal protection, so that it doesn’t overheat and become a fire hazard. Bad news, it locks up all the time, only can resolve it by flipping the circuit breaker. I’ve tried 3 different heater circuits, all with the same issue. It’s passive thermal dissipation still isn’t good enough when installed in a drafty hallway. Good luck and best wishes to anyone that buys this product. ... show more

  • Not accurate. Cannot be calibrated.
Not accurate. Consistently reads 5 degrees hotter than the room. I've had 2 so far and both have the same problem.
