I wish my dishwasher could automaticly start whenver the price of electricity was low. I can manualle delay it by doing simple math in my head and forecasting prices, but it would be easier and more foolproof if I could script it with IFTTT.

Your dishwasher probably uses ~1kWh of energy per cycle. Unless you're running your dishwasher a lot, or you're in an area where the difference per kWh is really massive, you're really not saving that much money.

Saturday at peek hours 1kWH cost me 4.27 DKK. Six hours later it was at 1.67 DKK. That's $0.4 saved per kWh. We run our dishwasher every day.

I doubt the cost in engineer hours would ever pay for your savings. Dishwashers don't use much water.

Normally I'd say someone should check the numbers, but this time I think you have better things to do...

In some countries with day/night tariff appliancies can trivially detect nighttime by voltage.

It's been used for decades and it's extremely cheap and reliable.

Our tariffs for electricity vary by the hour. I don't know how to detect that by voltage?

it's actually one of the reasons for wifi in miele dishwasher. it can fetch data about electricity pricing in order to run when it's lowest
