Is there some way to control the target_humidity and humidity enabled for the nest thermostat binding? I don’t see it on the binding page but it looks like it has been integrated into other nest control projects on GitHub.
Currently the official Nest API (used by the binding) only allows for reading the humidity.
There’s a developer thread about adding support for setting the humidity:
That is how it appears but I have found several references to others successfully setting the target humidity. For example this git hub project.
