Shelly 2.5 2-way switching

  • Hi! So.. i've got a strange problem, it's regarding a 2-way switching i've done or called "Button-Circuit" in the docs for diagrams


    SW2 = Connected to a Garage Indoor lights with a 2-way switch.

    SW1 = Connected to my outdoor lights (This works perfectly fine)


    But the 2-way switching (2-way physical switches) is weird. There is communication and both can toggle on and off. The issue is that when the State is OFF (In Shelly) . The furthest away switch cant toggle the state to ON or OFF

    If i turn the light ON in Shelly, then the furthest away switch work. But even if the lights are turned off by the switch, the Shelly App still shows that the lights are ON. So basicly it feels like my Physical Switches arent communicating with the Shelly app, even if they report proper Power usage and everything like that.


    One more thing. If i go to the first physical switch where the 2.5 is installed behind, I can turn the lights on and off, but it doesnt update the state in the Shelly App


    EDIT: Did some more testing, the first physical switch can change the state to On & Off both the lights and to Shelly App aswell. But not the 2nd one. If the Shelly App shows State Off then the 2nd Physical Switch wont work


    Same thing happens when i try to work with the first switch aswell.

    Could it be that SW2 on the Shelly 2.5 doesnt support button circuit? Or did i mess upp my wiring somewhere along the way.


    I used this as a diagram, except i've got this setup:
    Physical Switch 1 is a Double Switch ( This is where the Shelly 2.5 is installed behind )

    Physical Switch 2 is a Single Switch

    At which of the two switches does the lamp wire go on to the lamp?


    Could it be that this is on


    Physical Switch 2 is a Single Switch


    is?

  • The lampwire goes to the first switch, the one where Shelly plug is installed behind


    How do you mean is? :) I mean a Single Button Switch

    your power on default setting is on switch, so you cannot select edge. put on something else with Power on default mode.
