Need to upgrade this thermostat

I’ve had a TXU thermostat for quite sometime and ever since they upgraded to the “ Lux” it’s been nothing but problems for me. You think I’d of learn my lesson by now since this is the 3rd one I’ve had installed. It’s a piece of junk and the app never works in sync with the thermostat TXU needs to upgrade to a Nest or something better. So tired of messing with this piece of junk. I guess I’ll just get my own

Absolutely the most frustrating app and equipment I have ever owned. First of all the technicians that have installed the equipment did not program it properly to fit the heat pump unit I have. This ended costing me a higher electric bill during the winter months because my reversing valve was not functioning properly causing my cooling to come on and my auxiliary heating strip was my only heat. My thermostat continually keeps going offline to the point I have to call the company that installed it to reprogram it to get it back on line. And now I can’t even sign in to my app to view it because it keeps telling me I have no thermostats connected to my account. I have been waiting for a call back for 4 days for them to tell me what the problem is. Needless to say, my next call will be to TXU to remove this pile of junk ( nicest words I could put in this review)

IThermostat connection issues

It took me several technicians, a new outside unit blower motor, new air duck system, and a burned unit emergency electrical shut off outside to figure out that they installed the wiring backwards and had it programmed for a totally different type of A/C system. We figured out the upgrade way to save money was to only allow the temperature to stay at 84 degrees and connection losses after changing programs for daily and weekly it would reset to 84 but not in Texas and not this girl. A new Technician helped me take their control out and I don’t use the app anymore.
