How it works

From price to control in four steps

1
Fetch
Call /prices with your product code. New prices are published every day by 15:00.
2
Store
Save the response locally, so your control keeps working even if the network or the API is down for a while.
3
Plan
Pick the cheapest hours that meet your need, for example "car fully charged by 07:00".
4
Control
Send the schedule to the EV charger, battery or heat pump. Fetch again the next day.
