Two way switching a light

Hi guys ,
I have a switch down stairs and another switch at the top of the stairs controlling one light. How do I wire the sonoff light switchs ( TX) so they work together . I would appreciate your help. Thanks

Not exactly sure what your asking…

But I have Philips Hue Dimmer Switches, these have recently been updated in the Automations to control each button press

Maybe something like this?

Thanks ,
I am wanting to know the physical wiring of the if the bottom and top light switch ?

Do I run neutral neutral wire between the two switch , so that the second switch know that the state has changed?

I am not talking about the settup in HA as yet

Thanks

I have several of these and the wiring seems to depend very much on the country you’re in and the age of your wiring. For HA purposes I would strongly recommend Hue smartbulbs instead.

There are lots of wiring guides which you’ve no doubt looked at already - this one is for UK wiring.

Really?

The dual SPDT switch with traveller wires seems pretty ubiquitous. How else is it done?

Truth is, I have no idea, which is why I gave up. :grin:

Thanks , I have a guy wiring at the moment and want to ensure the correct wiring is done so that the Sonoff TX ( T3 ) work properly. He has rewired all my light switches and Lights with neutrals.
Now just want to make sure the correct format is used when I add the Sonoff to the bottom and top.

Thanks

It’s pretty simple. Use the existing travelling wires between the switches to connect both switches to the switch input. If either are changed the state of the switch changes.
