Finally got this to work. I did a factory reset but I believe the true
fix was forcing thermostat to 2.4ghz frequency... it does not like 5g
frequency. If you have a dual-band router like most of us do now, force
it onto the 2.4 radio and this should...
I am having the same exact issue. I have checked and verified the latest
update. When I reset the thermostat I can access it through the app for
awhile but then eventually get the error message in the phone app.
