Two gang switch : asking

my one gang switch gone bad but i do not want to buy new one because i have old 2 gang switch available.

is it posibble to control single light with the two button functioning. i.e whichever switch i presser, it will turn off or on the same light

It’s possible.

Using two scenes:

Wire your light to L1/N

IF - Smart Device - Switch CH2 on
THEN - Smart Device - Switch CH1 on

IF - Smart Device - Switch CH2 off
THEN - Smart Device - Switch CH1 off

can i do this?
L1-L2/N

no need to do scene

i tried th3 scene method, it not working
maybe because L2 not connected.

I don’t think it’s relevant. Which two gang switches do you have?
