Electricity usage

Hello,

I am using the electricity grid to measure my electricity consumption and it works well. I am using an ESP32 connected to my french linky and it retrieves my real time consumption. All the data are then sent to my MQTT server. I can see correctly the data in the graph.

However, I have some issues to add individual devices. I have some electrical plugs (tasmota friendly) that give me the real time consumption, I can add them in the dashboard and I can see their Kw/h. However I cannot have a stack consumption graph, the graph is only showing the total consumption and it is not splitted by device.

Do you have som clue to have this kind of information ?

Thank you in advance,
Bill
