Nest Thermostat schedule suddenly will not switch on in the morning

[DorsetDC]

Suddenly my Nest schedule is not switching the boiler on at 6am.  All was ok until 3 days ago.  I have turned off Home/Away Assist and Auto-Schedule since then but the problem remains.

Hi DorsetDC,

Thanks for posting here in the Google Nest Community. This doesn’t happen normally. Let's see what's going on. There are a couple other reasons why the Nest Learning Thermostat changes the temperature automatically, for example. If you recently turned off the auto-schedule, the previous setup might still be in effect. The same goes if you have already set up a manual schedule and remove it, there might be a chance that it will adjust the schedule accordingly. This is part of the Nest Learning Thermostat algorithm, but it can easily be fixed by starting fresh on the device. Resetting it and turning off the auto-schedule right away can do the trick. Follow the steps below:

1. On your thermostat: Go to Nest Learning Thermostat Settings Reset Schedule.
2. Go to Settings Nest Sense Auto-Schedule(Turn off Auto-Schedule).

Those steps will help us start fresh and clear out all the schedule and auto-schedule setup on the Nest Thermostat.

Keep us posted.

Best,

Renz
