Looking at electricity maps, looks like CO2 is delayed by about 3h and not realtime values?
~400g Co2 is around 8am on ElectricityMaps, but it’s at 10.55 on Home assistant:
~234g at 13, when it’s the value for 10AM
~130g at 4PM when it’s 1PM
This messes up a lot the energy calculations and provide a non real-time overview.
