 It uses the [geniushub](https://pypi.org/project/geniushub-client/) client library, which provides data compatible with the v1 API that _may not_ exactly match that of the official Web App.

+You can configure the integration either via the cloud API or the local API.
+The local API is unofficial, but is faster and has more features, while the cloud API is slower.
+To configure the local API, you require your **username** and **password** as used with [geniushub.co.uk/app](https://www.geniushub.co.uk/app).
+To configure the cloud API, you require a **hub token** obtained from [my.geniushub.co.uk](https://my.geniushub.co.uk/).

-## Configuration
-
-To set up this integration, add one of the following to your{% term "`configuration.yaml`" %}on.yaml`" %} file.
-
-If required, you can switch between one Option and the other and, as the `unique_id` remains consistent, state history will be preserved. This assumes that the correct MAC address is provided for Option 2, below. If a wrong MAC address was provided for Option 1, then the MAC address can be overridden for Option 1 to maintain these links within the entity registry.
-
-### Option 1: hub hostname/address with user credentials
-
-This is the recommended option.
-
-- Requires your **username** & **password**, as used with [geniushub.co.uk/app](https://www.geniushub.co.uk/app).
-- Uses the v3 API - unofficial, but there are additional features (e.g., battery levels).
-- Polls the hub directly (so is faster, say ~1s response time).
-- You have the option of specifying a MAC address (not recommended, see above).
-
-The hub does not have to be in the same subnet as your Home Assistant instance.
-
-### Option 2: hub token only
-
-This option is recommended only if Option 1 does not work. The MAC address should match that written on the back of the Hub.
-
-- Requires a **hub token** obtained from [my.geniushub.co.uk](https://my.geniushub.co.uk/).
-- Uses the v1 API - which is well-documented.
-- Polls Heat Genius' own servers (so is slower, say ~5-10s response time).
-- You should use the Hub's MAC address (although any valid MAC will do).
