Regarding the Energy Dashboard. There is electricity, gas, and water, but I miss the oil consumption. This should be able to be specified in liters. Actually, one could minimize the effort and rewrite the water logic to oil (should be mostly copy & paste). In the forums, there are countless entries where people somehow cobble together a solution that displays the oil consumption.
I think it should be included in the Energy Dashboard, just like gas and water are already present.
