If you're using the Intelligent #Octopus tariff with a #Tesla or other #EV, I've configured #homeassistant to save some money using a couple of automations.

Nice. Now, if only Octopus supported my car and charger - and if only my car had a proper open API. Sigh. One day....!
@ChrisWarwick annoying! I'm hopefully getting solar/battery installed soon and the inverter is similarly opaque to automation. Grrr.
