Due to the rising energy prices I have changed my Electricity supplier here in southern Sweden (Tibber) to one that bills me based on what the electricity costs when I actually use it (hourly), and that also has an API. So.. with an API comes the responsibility of making use of it of course.
I made this small application / website to tell me if its a good idea to take a shower or to wait, based on the electricity price right now.
Of course it only makes sense to you if you live in southern Sweden and have the same Electricity deal as I have, but if you do, this might be useful 🙂
