set the dishwasher to start at 3am because the regional carbon intensity forecast said 41 gCO2/kWh then vs 212 at 6pm. housemate says i'm in a cult. fair. the cult has a free REST API and i've written a python script that texts me when the wind picks up

National Grid's Carbon Intensity API, carbonintensity.org.uk. free, no key, half hourly forecasts by region. GB only though tbh

for germany i look at electricitymaps, not as nice as a free api per postcode. jealous

my dishwasher runs when the dishwasher is full which is never because i live alone and eat cereal over the sink

Very nice. I would like to point out that the smart dishwasher which can do this automatically will also send your usage data to the manufacturer. A timer knob from 2005 has better data protection. 🙂

mine is a dumb one with a delay knob, so the script texts ME and I turn the knob like a peasant. privacy preserved
