Nest Integration Thermostat has spurious Heat value

[puterboy]

The problem

I have had one of my thermostats set to ECO with temperature = 50 degF (32 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.
