Ok just received more switches so tomorrow can try again. Should have bought more as it was on sale but I needed one Gang instead of two. But two gang can use one of them as a wireless switch to control other things.

Hopefully just that particular switch causing the trips or maybe a weak elcb 🤞
Just doesn’t makes sense as there is nothing special about the backup circuit.

So I have some time to be spared just now to test out the Sonoff POW, I decided to test it on my ventilation fan.
Luckily after the testing, I am still alive and here is the picture:

The power consumption measured by Sonoff POW is as follow:

From the measurement obtained, 17W versus from the spec 34.4W.

The indicated power rating on the fan probably not the motor electrical power usage but mechanical shaft power rating.

I'm not sure if the Sonoff pow is measuring just real power only or both real and reactive power. hmm.gif

ozak Zot weikee okay must summon all the big sifus

this is really weird.

1. proceed the install the newly arrived switches
2. put in just Live red wire and L1 to to Red wired lamp = okay didnt trip
3. put in L2 to Yellow wired lamp = trips

The other day I put in Yellow side on its own, it didnt trip


Original Switch - 2 Gang Switch. One Red Live One Yellow Live (different circuits)
Aqara Switch - has only 1 input for Live so I can only use either Red or Yellow
Red goes to a backup service in case of no electricity
Red ELCB tripping.

What should I try now? bangwall.gif

Yellow wire you try both? 1 should be from the DB, 1 to the Lamp..

or if use yellow live, instead of red how? live yellow.. L1 to yellow lamp.. test 1st.. then replace L1 with red lamp.. test.. if ok try connect both to L1 and L2.

I think I understand liau.

The yellow wire is from another phase. You cannot use yellow phase join to red phase. It will trip.

Red live have to go back to red wire. And so do blue and yellow.

I use Yellow Live and L1 Red wire to lamp also trips - really weird
So that means if got one red and one yellow in the circuit it will trip
If yellow and yellow - okay
Or Red and Red - okay

Can rewire at the CB side?

Or to have an external switch with a box outside my regular wall switches - fugly lor doh.gif

If you know which one goes to which one, why not? You can separate them in DB box. Of course wires are separated by color coding in DB, right?

The main incoming switch will cut off all supply. Additional isolation would be pulling out all phase fuses outside the house at the meter smile.gif

Yes. Big and bulky switches look scary. Once you start doing and get use to it, you become lazy and careless, like no need to go downstairs to switch MCB off laugh.gif

3 Phases? All Live (Red, Yellow and Blue), have to go back to Neutral to complete circuit.

Don't short phase. If you DB don't trip, your house will burn.

not shorting phases but one live wire feeding two different phases (lights)

Most autogate switch is momentary switch, aqara swich is not momentary switch, so mostly you can't simply do 1-1 replacement.

Better open up your auto gate system / switch to have a look.
i bought a switch only to know that the wall switch are dry contacts.

ended up fitting my aqara switch to the toilet fan in the end.
