One thing i like on these so called MCB's is every item on the list they do, can be on or off. So if you want to use the meter part & the time switch to lets say control lighting for security, then that's all you use. The rest can be left switched off. You only dial in what you want. & at around £10 each its not bad.
How would you clamp meter a ring main ??

They’d have some specific uses for sure
Controlling specific circuits subject to their rating which cant be relied upon . If they say 16A you still wouldn’t be switching an immersion direct with them
Definitely not a road you want to go down having a multifunction gadget per circuit
Domestic circuits in the main should be normally energised

I can see they have their uses.
Personally I wouldn't use them unless the protocols were documented (or reverse engineered by someone smarter them I am) so they could be quarantined on their own network and talk only to software running on my own server. Doing that, wouldn't be too hard to setup multiple registers for different tariff rates.
Adding extra devices, extra box, lots of extra connections.
Vs. Slipping a toroid over each metered circuit. If your pedantic about regs, still add an extra box, but don't need any extra connections.
Either can be as accurate (or otherwise) as the measuring system supports. Many can do true power measurement by having a voltage/phase input. One of the "round tuit" projects on my list was a 16 channel monitor design I came across a while ago - true & reactive power, power factor, voltage, current, all high accuracy with a dedicated measurement chip.
They are rated at 1-63A & you dial in via an app what Amperage you want them to trip at, so i would trust them with an emersion at 13A. But i would only fit them after an already fitted RCBO board with correct fusing. So i assume they could be left set at 63A as the RCBO would be the safety part of the circuit .

They're not in any way a replacement for an MCB
The overcurent shut-off feature they mention would probably have some specific uses
As for their claimed 63A rating
on a gadget marked AliExpress
Very true & that's partly why the RCBO board would stay in place. Someone should have ago at the Chinese as they have a lot of misleading information on selling their products. IE: Why advertise a 13A adapter that you can plug 20A/4.5kw into. Personally i would only plug 3kw into a UK socket for a short period of time & only 2kw max for longer periods. It might be why many appliances are nearer 2kw these days.They're not in any way a replacement for an MCB

Reminds me a bit of some of the HiFi stuff that was advertised as so many watts of power and plugged into a 13A socket, hmm , that added up all the different quoted power outputs from certain parts in certain modes and added up as somewhere around the power which could not be used all at the same time.
A bit like a certain athlete can jump two feet, can jump 5 feet, can jump ten feet, can jump 12 feet (cos he is capable of jumping about 14 feet) so the add all of that up and says he can jump 29 feet and more!.
Yes OK then ???
