Energy Manager [DK]

1. Add repository URL to Home Assistant Add-on store
2. Install the Add-on in Home Assistant
3. Configure the Add-on:
   • Region is mandatory
   • Carnot Username is required only if using Carnot.dk predictions
   • Carnot ApiKey is required only if using Carnot.dk predictions
   • Eloverblik Token is not used yet - but may soon replace tariff configuration
4. Spot price values are all created as sensor.energy_manager_*
5. Confirm the tariff levels in config/energy_assistant/tariffconfig.json (recommend using Studio Code Server to edit it)
6. Configure spot price levels in config/energy_assistant/spotpricelevels.json (recommend using Studio Code Server to edit it)
7. To add some graphs using ApexCharts (from HACS) see below
