I was so worried when the remote that I have to my smart thermostat broke the other afternoon. I got the remote because I really do not like using the app that is on the iPad and my cell iPhone. These remotes that they sell for smart thermostats are built really cheap. I have only had this remote about 3 months and it already broke. They are not too costly to buy, it is just a pain in the rear having to go out and buy another a single after only 3 months of having this a single! Will the next remote break in the same amount of time? I am not sure. But I have to supply it a shot because I want to be able to control and program my smart thermostat separate from having to mess with the cell iPhone app or my condo iPad. The only way I would ever want to use the app on the iPhone is if I am out and want to turn my central heating and a/c on or off, then controlling the central heating and a/c while away is the main benefit of the smart thermostat anyhow. It has saved me a lot of money on my electric bills this way using far less energy. Because the central heating and a/c would have to run all the time when no a single was condo otherwise. This brillant smart thermostat makes it so that no longer has to happen. I just hope that I can have a quality remote control this time around to control it from home!
