No Home Assistant component for Vine Thermostats at the moment.
Not really sure what the point is of a smart thermostat if it can't be integrated with one of the most widely supported smart home control systems.

Very different than alexa/google. This is smart home control for the enthusiast and/or anyone that wants to limit how much of their data goes to corporate cloud data. Considering there are 1000+ services supported by HA, not having that support would be a deal-breaker for a lot of would-be early adopters.
