Inspired by this Mastodon account, I programmed an ESP8266 microcontroller to act as a traffic light, indicating the current electricity mix. Check it out on Codeberg! It uses an API from the Fraunhofer Institute and the parts cost around 5โ‚ฌ. In my shared flat we use it as an indicator on when to run demanding devices, like the washing machine.

Oh, sorry, didn't understand it like that ๐Ÿ˜... thought that was the price of the license for the library ๐Ÿ˜.

Of course, the parts come at a price, no surprise there ๐Ÿ˜‚.
