State water heater is a sister company of A.O.Smith. I think it is using the same API structure as A.O.Smith. However, it is using a different URL or entry point for authentication. (I think they are using different database for the customers information). In any case, can you add support for the “State water heater”?
Here is some background from google " A. O. Smith operates under the following brand names around the world: A. O. Smith (United States, Canada, China, Europe, Turkey, India and Vietnam), GSW (Canada), John Wood (Canada), State Water Heaters , American Water Heaters, Reliance Water Heaters, Lochinvar, Takagi, Giant Factories Inc."
