Octopus Spain

Octopus Spain is an integration that reads the latest invoice and Solar Wallet balance from an Octopus Energy Spain account. It adds sensors to Home Assistant for the Solar Wallet value in euros, which matches the last invoice and is not available in real time. Another sensor shows the Octopus credit from referred accounts or other bonuses, and one shows the cost of the last invoice. The invoice sensor also carries the issue date and the start and end of the billing period as attributes, which can trigger automations when a new invoice is issued. Setup is done in the UI with the email and password of the Octopus Energy account.
