1PM Australian/NZ Two Way (Hotel) Switching

  • 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
