Great that the app now shows the data for last session of charge and the COST of that charge. Why not add the cost of the charges to the data for weekly , monthly, annual and all charges. I appreciate that KW charges may change for the consumer every now and again but surly that can be built into your algorithm?
v 1.3.4 of the app adds charging logs and consumption for individual chargers, can be found in the "Charger consumption" on the product card.
Here you can also see total monthly and annual cost, or see cost per session :)
More advanced consumption features in the works too + more detailed charging timing info.
