Any suggestions for the above? Galvanic isolation or non-contact with Current transformers.
Safety first as this will go into my main breaker box. I will be interfacing a custom STM32 solution and/or Raspberrpy Pi
Also power draw W / VA measurements will need to be processed.
Thanks so much.
Kind regards
Mike
Do you trust Arduino firmware? 
Why not? None of the firmware is doing anything safety critical.

Oh gosh no. I’m doing bare metal Rust on STM32 H7. Riding mbed is toy code at best.
Agreed. Try toggling an IO in arduino and measure the delay on a scope. You’d be shocked!
Imagine doing anything half decent. The latencies are ridiculous. And that’s the start of it.
With Embassy and Rust async building an RTOS from scratch is possible.

There's nothing fundamentally wrong with Arduino as a platform if it is used appropriately.
Professionals evaluate the hardware platforms available to them and their customers and make a decision on that basis, rather than just ruling something out because "eww, Arduino".

Until you have to put together a test setup that is easily maintained by others. Can you name any other platform that is as popular? The main advantages you might get going with some other platform - cost and performance - mean little for most test setups. Also see why test scripts are typically written in Python rather than C++, maintainability is more important than performance.
