Danfoss Ally

This is a custom component for Home Assistant to integrate the Danfoss Ally and Icon devices via Danfoss Ally gateway

Download the latest release.
Unpack the release and copy the custom_components/danfoss_ally directory into the custom_components directory of your Home Assistant installation.
Restart Home Assistant.

Setup

First of all you need to go and create an api-key and secret

Navigate to https://developer.danfoss.com
Create Danfoss developer account and login NOTE: Use the same email as used in the Danfoss Ally app for pairing your gateway
Go to https://developer.danfoss.com/my-apps and click "New App"
Give the app a name and description (naming and description is not of any importance as it's only for your use)
Make sure to enable Danfoss Ally API
Click create
Save your key and secret - these will be used when adding the integration
Go to Home Assistant > Settings > Integrations
Add Danfoss Ally integration (If it doesn't show, try CTRL+F5 to force a refresh of the page)
Enter API key and secret

Voila

Inconsistency between API and app, devices are not updating correctly between API and app and sometimes the devices renders offline in the app - this is a Danfoss issue and not this integration
