Elvia Grid Tariff for HomeAssistant

Forked from sindrebroch/ha-elvia, go buy them a coffee if you want to.

HomeAssistant-integration for Elvia

Notes and changes from sindrebroch's version

Firstly, the name of the integration has changed. There is a different Elvia integration available, so to avoid shadowing its name I've chosen to call this one "Elvia Grid Tariff".

Secondly, I tentatively have not much interest in improving this integration beyond small fixes to keep it working through Home Assistant-upgrades; which was the initial spark to fork this to begin with. I'm happy to receive help through PRs and issues to improve the integration though, and maybe that'll motivate me to improve it too. Ideally, sindrebroch returns at some point to merge the changes proposed already, then I'll probably delete this fork.

If others want to contribute to this, I could also transfer this to a GitHub organization to more easily manage maintainers and such, but we'll cross that bridge if we get there.

Requirements

• Metering point id. (Målepunkt-ID, not Målernummer) Log into Elvia and find your ID.
• API-key. Sign up for GridTariffAPI at the Elvia developer portal. You may retreive the API key in your profile (the primary key should be sufficient).
• Token. Read how.
  • The short of it is: log into Elvia, under "Andre tjenester" select "Tilganger".
  • From there, select "Opprett token for målerverdier i API".
