Electricity Maps gave us quite some trouble in the last months :(
Sadly they have not continued their offering for a free worldwide CO2 grid intensity through their API. The product was called "CO2 Signal" at the time of launch but discontinued.
The reality for Eco CI was: No more location based carbon intensity data and thus no more CO2 display at all :( :(
Thanks to the idea from @mrchrisadams we have now integrated a constant grid intensity option that is actually the default.
The default from Eco-CI is 472, which is the worldwide average value from Ember compiled by The Green Web Foundation from https://github.com/thegreenwebfoundation/co2.js/blob/main/data/output/average-intensities.json#L1314
Read up in the readme if you still want to continue location based data with APIs like ElectricityMaps if you have a global premium key.
