-The Point hub enables integration with the [Minut Point](https://minut.com/). To connect with Point, you will have to [sign up for a developer account and have a Pro subscription](https://minut.com/community/developers/) and get a `client_id` and `client_secret` with the `callback url` configured as your Home Assistant URL + `/api/minut`, e.g.,  `http://homeassistant.local:8123/api/minut`. The `client_id` and `client_secret` should be used as below.

-Once Home Assistant is started, a configurator will pop up asking you to Authenticate your Point account via a link.

+   - Enter `https://my.home-assistant.io/redirect/oauth` in the **Redirect URI** field.
