Just adding my diagrams for two way and three way switching as well. This uses the NZ/AUS wiring where the slave switches are cabled (usually) with Red/White/Blue WiresScreenshot 2022-04-18 at 12.53.32 PM.png

Hi,

I have read though all the posts I can find on two way switching I can't find one that I applied to the 1PM . In New Zealand two way switching uses 2wire method. (Changing the wiring is not an option as it goes against the standard). (I know there is a better way!)

After discussing with the electrician this is his proposed solution - but he stresses he knows nothing about shelly! The secondary switch is feed by a three wire cable with red-white-blue cores. In this situation (for two switches) On/On or Off/Off will mean the light is on and On/Off or Off/On will mean the light is off.

Is the proposed solution below correct? And I know I will have to set the shelly to edge mode.

Thanks
