Nest API reporting thermostat as OFF on scheduled temperature change

Configuration
1

Hi,

I have an home/away automation that stores the state of my Nest thermostats (cool, heat or heat/cool) to a variable in order to set it back to that mode upon return home. This was working flawlessly until recently, when the Nest API started reporting my thermosat as OFF when the preset Nest schedule activates in the morning. For example, my schedule is set to increase the temperature from 18 C to 21 C at 6:15 AM, and I get the following in the Nest debug log:

Anyone have any idea what the issue is?

It’s worth noting that I have a second Nest thermostat that isn’t affected by this.

Mine has also randomly changed to off every now and then recently (sometimes for seconds, sometimes hours). I haven’t dug into it (other than confirming it’s definitely not turned off). In my case it’s been fairly rare (maybe once a week?).

Just had this happen this morning WHILE it was heating, it randomly switched to off (HA correctly showed it actively heating but that the current mode was off). A manual restart of the integration fixed it.

I am seeing the same here. I hadn’t realized that it was happening on a scheduled temperature change but hat is indeed the case for me too.

In the mean time I have created an automation that looks for the “off” state and reloads the integration.

In my case, it’s not happening with a scheduled change but it MIGHT be happening when it starts heating/cooling early before a change (I have it setup in the Nest app to try and hit the new setpoint at the time of the scheduled change).

Regardless, it’s definitely not consistent. I have several scheduled changes every day but it’s only showing ‘off’ maybe once a week or so. I’m guessing it’s just the API sucks.

Also, I don’t have a good idea when this started as I’m mostly apt to notice it in the winter, not the summer (northern hemisphere). I don’t have a memory of it doing anything like this last winter.

I’ve noticed this behavior and more as well. I always have my thermostat in Heat-Cool mode. I’ve seen Home Assistant report OFF while the thermostat is idle (temperature between the low and high points), and I’ve had it report that the current mode is Heat while the thermostat was actively heating, but the thermostat was actually still in Heat-Cool mode.

I’ve experienced a similar issue as reported here:

It seems to me that the thermostat cycles through OFF when the mode option is used in the service call. So I’m now experimenting with a service call that doesn’t use the MODE option. I’m likely down a rabbit hole, but we’ll see.

I’ll mention, that at least in my case, I’m not interacting with the thermostat with HA; I’m simply pulling in data FROM the thermostat into HA. I have schedules setup in the Nest app and it’s on these setpoint changes that it periodically shows an ‘off’ state in HA. I notice it every few weeks, so it’s very random.
