I ordered one from different seller and expect to receive it at the end of this week.

My first try will be driver: Zigbee Switch Power Mc

Maybe I overlooked something, but from what I read, it is not a circuit breaker, it is a high current switch with or without energy metering, which can be placed on a DIN rail.

It does not have overcurrent protection and does not cut the switch if the current exceeds or there is a short circuit in its installation.

Maybe @Mariano_Colmenarejo could contribute for more info, he’s a beast on Zigbee drivers

Hi @dusanhauko - did you ever manage to configure this somehow?
Tnx!

Yes.
I have a few of them for ceramic heaters on patio and also for running 12VAC water valves. Working with official Zigbee switch driver or also with Zigbee switch power Mc.
Happy.

Oh cool - does it offer any power accumulation over time as well?

For last 30 days it shows daily sum with graph as usual. Then it also sums from begining of usage without any graph

That’s great. Do you use it only as a monitor or also as a circuit breaker for overpower protection?

As @Mariano_Colmenarejo noted above, That device is not a “circuit breaker” that provides overload protection as defined in US, UK, or EU safety codes.

It’s true that many of the companies that sell this device describe it in English as a “Smart circuit breaker,” but it just isn’t. It’s a DIN Relay with power metering. You can see how much energy is being used, but it doesn’t automatically cut the circuit the way a real circuit breaker will.

And it’s not safety rated to act as a circuit breaker.

Tuya does make smart circuit breakers, but they look different: you can see that they have a tiny external handle instead of a button.

The reason is that since real circuit breakers will automatically shut themselves off when there is an overload condition, the various safety codes require that you be able to look at the circuit breaker, even when there is no power from it, and tell whether it is in the on or off position. You can’t do that with a button device like the one being discussed in this thread. When that one is “off,” there is still power flowing through it so that it can process the next “on“ command.

The smart circuit breaker, however, the real ones, generally have to be manually turned back on. So they have the little handle design so that it is very easily visible whether it has power flowing through it or not.

The one under discussion in this topic may still be useful, depending on the details of your specific use, but this is just one of those cases where a commonly used translation gets it wrong, which can definitely be confusing. :thinking:

Used as relay besides normal circuit breaker. Just to make dumb things smart and keep organized wall box.

This is correct. I have come across this feed trying to find a driver for it! I have got the two pole type with power metering. I have installed your Zigbee Switch Power Mc but it doesn’t identify the driver. It is labelled Oumefar Smart Breaker, and comes with the usual mixture of incorrect instructions…
Any pointers to a possible driver would be welcome.
