Just got a new Ecobee and trying to figure it all out. Was a nest user, but they discontinued support of my nest thermostat, so switched to Ecobee.

I have the thermostat in my dining room and a sensor in my master bedroom. The thermostat is set to 69, but the sensor in my master bedroom keeps showing 75. How do I get the upstairs bedroom cool like the downstairs thermostat? I have the registers mostly closed downstairs trying to push the colder air upstairs. But, it just doesn’t seem to be working. The A/C just doesn’t seem to stay on long enough to get the colder air upstairs. I don’t use any schedules because I work out of the house and we are always home.

Thanks in advance for any advice.
