arduino mkr wifi 1010 + zihatec mbus master

Hi,

I'm thinking of getting info from my power meter ( emh diz-w1ed-00-lm0-0m-200000-g50/k ) using an arduino mkr wifi 1010 and a zihatec mbus master shield then passing all the data to home assistant via nodered.

What exactly would I have to provide via http ?

I'm currently writing a sketch to get the frames and decode them.
All I need is V,A,W for all 3 phases for now.
