I ordered 2 units and accidentally used the wrong credit card. After some back and forth they were able to refund the wrong card and charge the correct one. Both vent fans are working seamlessly with my Nest system and the room is 2 degrees warmer.
Our oldest child's bedroom has always been cold in the winter (even with two heat vents (maybe too far of a run from the furnace?). We bought one of these to put into one of the vents to try it and see. We couldn't believe how well just one worked. We decided to buy another one for our other daughter's room. I was concerned because the price went up after we bought the first one, but when I explain this to the support rep they said that they would honour the previous sale price for the new one.
Great product. Integration with thermostats (Nest & Ecobee) makes it effective (runs only in rooms where the temperature threshold isn't met).
The only downside is the sensor which requires that it be tied to a fan. So, you cannot have 3 sensors in 2 rooms. It has to be 1 :1.
I bought this for the automation aspect. It took less than 2 minutes to get it connected to my NEST and wifi for setup. VERY easy installation. The only thing I could add is that it would be nice to have a little bit longer of an extension cord. However, the cable isa bit over 5ft in length. The room I put it in had power outlets 6 feet away. A powerbar was a quick fix.
Works on a schedule. Great
