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.
Are there any creative energy sinks you could run when the price goes negative? I can only think of mining crypto or transcoding video or stuff like that.
Dingdingding! Correct. For the chepest two hours a day (or any time cost is negative) Home Assistant gives Portainer a kick and I sail the high seas. Whenever costs are negative I saturate my servers with BOINC CPU-heavy workloads like ClimatePrediction, Rosetta@Home, LHC@Home and World Community Grid.
Flip side of heating could be to lower the temperature of freezers. If the energy is free anyways.
One of those giaaant resistors and a significantly higher current service from the utility!!
