The IVT Aero heat pump series connects to the Bosch cloud API (https://pointt-api.bosch-thermotechnology.com/pointt-api/api/v1), similar to the K30 RF wifi module discussed in bosch-thermostat/home-assistant-bosch-custom-component#335. Unlike the local HTTP and MQTT integrations supported today, this access method requires an OAuth authentication flow, which provides access and refresh tokens.

Although this approach differs from existing local integrations, the data structures returned appear to be similar, making it a potential fit for integration into this package. I have successfully connected to the API and can both read and write data, though the available data is somewhat limited, it's really stripped down to only allow what's used in the ‘IVT Anywhere II’ mobile app.

I'll publish a PR once I've got the sensors mapped up and can read and write it through the client, but writing now just to check that it makes a good fit? I'm looking at this part first because I want to integrate it into the home assistant component next.
