I’m planning to move to a variable tariff-model like tibber or awattar.
To plan for that I’d like to “simulate” my current consumption with live-data from one of those providers.
But: to use either bindings I have to have an account with them, which I don’t have presently. Is there anybody having similar or same requirements and managed to get it running already? Perhaps there is already an free-to-use API in place, which I didn’t came across?
Tibber allows you to play with their API using a demo token, so you can get prices, and consumption for a simulated home. I guess it won’t work with the binding, but it can let you experiment a bit if that’s what you’re after?
Yes, I just realized, I only need the marketprice / “Börsenstrompreis” for each hour and can then calculate my consumption. So I guess, that’s all I need to put it in a rule for a “actual consumption”.
To make it a bit more complicated I could already start implementing EV charging or powering other switchable consumers to the future marketprice coming out of those API-calls.
The price seems to be for Stockholm (price area SE3), so might not reflect the price you would get, but should give you some data to work with at least.
IIUC, the Tibber price model for Germany is based on epexspot market data:

I wouldn’t trust the prices from the Tibber API (Bewertungen zu Tibber | Lesen Sie Kundenbewertungen zu tibber.com).
