I have bought an Easee charge station for electric vehicle, if I get a good input from house total usage of the 3 phases I can load balance the charger depending on house power usage.
My question is which is the best/ easiest maybe cheapest way to see power usage of the 3 phases into Home Assistant.
is it using a modbus normal powermeter such as this

or this zwave DIN version
or better using something like this zwave with xcurrent clamps
or this which seems to see voltage per phase

or something else?
