The UK is currently experiencing some prolonged windy weather and my all-renewable energy provider offers dynamic pricing. That means cheap energy and even negative-cost energy. This is where my HA instance shines and saves me a fortune on my power bill. Thanks again to the HA devs for this incredible project.
For the curious, I'm using bottlecapdave's excellent Home Assistant Octopus Energy integration via HACS.
I'm looking forward to going over to Agile in the near future.
I was under the impression that you had to be electric only, but apparently you can have a standard gas tariff alongside. We just need to work out a few things like "how much could it cost us to make dinner during the peak?"
