ESP32 for 3 phase energy monitoring

Hi all,

I would like to build a ESP32 for 3-phase energy monitoring. Currently I have an old ferraris-counter which I tried to log with an tcrt5000 - but it is unreliable as hell :smiley:
To have more precise values i would like to use CT-Clamps for this - but I did only find guides for single phase monitoring. Any hints?

I use one of these for single phase, can you just use 3 of them connected to ESP ?

Or this, not tried it though

There are some other CT recommendations in this topic:

Thanks! I will have a look at the PZEM-004T
Found a german guide with tasmota:

Have a look here also:
