Hello everyone,
Since the only way to control devices based on the electricity price in the phone app is in percent of the price average (which does not account for minimum price during the day) I made a small python app with a web interface where you can set cutoff prices in % of the daily price range for different devices (you can create as many as you want and control them all on one page).
The app provides a json with on/off values (1 and 0) for all appliances you create which Thingsplex can get using a GET request. I am using these to have my water heaters run only couple of hours a day when its cheap and set the floor temperature high or low.
For the time being it can only get prices from the Tibber API. Let me know if you find it useful and wether you want some other price provider to be added.
You can get the app here:
Thank you for sharing this!
