Nest Integration Thermostat has spurious Heat value

[puterboy]

The problem

I have had one of my thermostats set to ECO with temperature = 50 degF (10 degC) for 2 days now without changes.
This morning, I noticed that HA shows the value at 32 degF (0 degC) even though nothing has changed and the thermostat itself as well as the Android App still show ECO mode with temperature = 50.

Querying the Google Nest API using CURL, shows that the heat setpoint is indeed 50 degF.

So somehow, the HA Nest Integration recorded a spurious change to 32 degF (0 deg C) -- given that the core units are Centigrade, it seems as if the HA Nest Integration somehow just set the value to zero

This may a slightly different issue but I've also noticed a delta between the temp reported in HA vs the temp on the nest app.

[robsug90]

Also having this issue with Nest Thermostat reporting incorrect temperatures in HA. In the Nest app it works.

[allenporter]

Presumably the pubsub feed is publishing incorrect events. Can you enable debug logging for the integration? We need to capture logs when it transitions to this happening, e.g. when it sends an event message that is invalid

[robsug90]

Here's a few days of logs
error_log.zip

[allenporter]

@robsug90 Thanks for collecting the detail. The other bit we need is if this happened again: around which time during this log did you see the problem? Nothing stands out during this time from a quick look.

[todanator]

Sorry I suspect my issue is an error from pubsub events from Google like this issue.
#110010

[IngmarVerheij]

(not sure if this the same issue, but its plausible)
When displaying the Nest in Celsius there's an offset as well. Nest is configured to heat to 20.5c, but home assistant reports as 20.3c

I also have same issue - reloading Nest Integration entries temp fixes it but issue comes back

[iTrim]

Look for nest entry ID in /homeassistant/.storage/core.config_entries

Then create a new automation or paste into YAML

alias: Nest Script
description: Reload nest every 5mins
triggers:
  - trigger: time_pattern
    minutes: /5
conditions: []
actions:
  - data:
      entry_id: PASTE NEST entry ID HERE
    action: homeassistant.reload_config_entry
mode: single
