Energy usage clamp meters (feddit.uk)

As I'm currently doing a re-wire, it's a great opportunity for me to put some metering in the house.
I'm single-phase, but I plan to monitor multiple sections of the house, which are each wired for 100A independently.

I'm currently eyeing up either the Shelly Pro 3EM – 120A or the 50A.
As it will fit nicely in the consumer unit, and supports Ethernet.

I previously looked at the Aeotec clamp devices, but they seem to be difficult to find with multiple 100A connectors.

Emporia Vue was also a consideration, but I'm always a little hesitant to buy products that require custom firmware to even work properly, when others are available. And I'd also like to avoid using 2.4Ghz wifi for connectivity.

I'd love to hear any experiences people have had with similar devices, good or bad. And how the integration with HA went.

This is something I’ve looked into in the past as well and with about 35 circuits to monitor, the Vue seems like a good one and done solution except it’s way too small, AND there’s mucking about with firmware which I’m none too excited about. I’m waiting for something better.

Shelly, if you're listening: Smart RCBOs would be interesting to explore.
As would a product that can handle, say, 16 clamps, and you buy the clamps separately.
