Nest Thermostat config utilizing the new climate rewrite

Share your Projects!

Hi All,

I wanted to share my Nest config for everyone. Seems some people are having some issues with the new methods that the climate component uses, and hopefully this helps someone out or gives them some ideas.

Let me know if you have any questions, improvements, etc to this.

## Nest package - Includes base Nest thermostat configuration, away mode switch and sensor,
## Runtime for the day and month, and manual fan control.

This is cool but its not working for me … I placed in a Yaml file inside the packages folder but nothing keeps giving me errors…

Any ideas ?

What errors are you seeing?

Did you make sure to set the secrets in secrets.yaml?
Did you make sure to change the climate.nest to whatever your thermostat entity name ID is as well?

4

Inedententions are fine ?

What is the reason of binary_sensors ?

Thanks for sharing this! Have you found that that when you come back from “Away” mode that your HVAC mode always changes to “Heat and Cool” regardless of whatever mode it was previously in (i.e. “Heat” or “Cool”)?

The Binary sensors are created from the Nest component itself. The Fan sensor is a requirement at a minimum. The others I use for monitoring and are optional.

I have not noticed this as I leave my thermostat in heat/cool mode year round. I will play with this a bit tonight when I get home and see if I can work it out.

You may want to try the alternate method of using the nest.set_away_mode for the template switch and see if that helps out.
