Now with location-based controls, you can program settings to start and stop your heating and cooling when you are close to your home or business based on your smartphone’s GPS location. The TXU iThermostat™ app allows you to remotely adjust your thermostat’s settings, or quickly put your entire home or business into energy saving “Away” mode with the tap of a button.

I have had the TXU wifi thermostats from when they were first offered to me about five years ago. I really liked the system, the controls and graphics.
This update however is a step backwards. I find it hard to use and regard it as a way to lower my control of the system while increasing my energy consumption.
I rate this App as very low (I cannot give a minus star) and I am currently shopping around for other wifi thermostat options so I can have this system removed.


Latest update messed it up

It used to work, but when I last updated it, it does not work because I can't log in. I requested for a "forgot password," and I still can't get in. It keeps taking me back to the sign in screen.

Also there is about a 2-3 degree difference in temperature between the app and the thermostat.



I would be ok with this app, but the temperature is never the same on my iPhone as the thermostat in my house... always off by 2-3 points. This is frustrating and probably costing me more money.
