I have a Shelly 3EM 3-phase energy meter configured in my home assistant. So far it works fine and I get the data for the 3 phases in the energy panel and I can use them as separate data sources in graphs etc.
I would like to generate some kind of “energy heatmap” like e.g. here. That would make it possible to see much better when how much electricity is being used when.
I see that the apex charts has some heatmap/carpet plot functionality, but I am not sure how to use it together with the shelly data. Maybe somebody has already made a energy heatmap and could point me in the right direction? Thanks.
