Another switch question

Yeah ; as I’m out my depth completely I won’t be doing any of that .

Whats the worst that can happen getting Live round the wrong way ? 🙄😫

It won't work.  So if not swap them around.

Nothing bad then ! - that’s what worries me . I’ll try and see tomorrow. Really don’t like this stuff ; appreciate your help !

Another way to test. 

 

Do you have a spare table lamp? 

 

Take the plug off it, put the blue wire in with the neutral in the wago. 

Put the brown wire in the other terminal in the switch. 

 

If the switch flicks between the main light and the lamp, then the common is the feed. (the perm live)

I'm still confused on the no neutral thing (I didn't realise this switch didn't need a neutral ).

 

With no neutral and the switch off it won't be powered and therefore surely can't report or be controlled via Zigbee?

But if neutral is connected ( where too? ) then it is 'powered' and so acts like a smart switch correctly?

 

No understand. Switch is neutral free. Destructions show neutral connected to squiggle ( why a squiggle?; what's it meant to represent - not seen that before ). - confusion

 

hate electrics - so dangerous.. I might send it back

The smart switches which don't require a neutral work by still sending tiny amounts of current to live even when the switch is off (in order to complete the circuit) and use that to charge a capacitor which powers the ZigBee gubbins.

So smart switches are not ‘green’ because they use a small current even when switched off 🤷‍♂️

Only the 'no neutral ones', and the current is miniscule
