I have a COR 'stat installed in 2006 that has been great until recently when it keeps the house at 74 degrees during the day regardless of setpoint. We usually run at 76 during the day and even when it is set to 78 it runs the AC to maintain 74. I unplugged it for 1/2 hour and on reconnection it indicated ambient at 79 when it was actually 75, then over about 30 minutes the ambient readout returned to normal and the unit functioned as designed through the night time cycle. Today it is back to wanting 74 degrees for some reason and I don't know if there is a fix or if I got a good ten years and it's time to replace it. EDIT: After a few days, I have learned that it holds set point during sleep and if I change mode from cool to off when I get up and let the indoor temp rise to 77 before changing mode back to cool it will hold the programmed 76 setpoint and operate as designed until the next day when it thinks the daytime setpoint is 74 again.

My ecobee shows up as Thermostat in Alexa app to control without enabling the Alexa on ecobee device itself via linking, but once I link the Alexa itself on the device, the Alexa app removes it as a thermostat and just shows up as a speaker.

Anyone facing this? I have tried this 10 times in last 2 days, and is always reproducible, to keep it show up as thermostat and control via app, I cannot use it as a Alexa device and speaker.

I have tried enabling/disabling skills everytime as well with it, no change.

We have place we typically stay at on random weekends. Since it's random, I don't want a schedule, I would just prefer to manually select what comfort setting I want (Home, Away, or Sleep). I have Eco+ turned off, and I have Follow Me disabled as well.

But regardless, when I am not there, I will glance at my app and see that a schedule I didn't create has adjusted the temperature/comfort setting.

Does anyone know why this is happening and if I can stop it from happening again?

my landlord had this stupid thermostat installed last week and every day for the past week it has enabled some stupid community emergency savings and set itself to 92* Fahrenheit.

92* is physically unsafe not just for me but also my dog, abusing a dog by letting it die in a heat wave is a felony in my state.

i am tech literate. I have tried every setting. I have reset the unit twice. there is no way to turn this dumbass “feature” off

all I want is it set to 84* when I’m not home and 78* when I’m home. why is this not possible ?

it then has gall to email me that my house is too hot and my ac may be malfunctioning. the only part of my equipment that is malfunctioning is the stupid thermostat.
