Actions - Output switched ON url

  • hi there, new here so bare with me ...

    using an RGBW2 and a shelly PLUS2PM connected to my wifi router, AP mode disabled.

    configured an action on the RGBW" (Output switched ON url) to communicate with a script running on the PLUS2PM.

    when testing this with both shelly on my desk everything works as expected.

    after moving the RGBW2 to its desired place, some 20m away from the PLUS2PM the Output switched ON url) doesnt work anymore. both shelly still are connected to the wifi router and are reachable from the computer in the same network.

    my question now is:

    does communication between shelly devices when using this Output switched ON url action take place bypassing the wifi router so the shelly devices are communicating to each other directly instead of communication through the router?

    and another question:
    what does the setting Device discoverable mean? its enabled by default and when disabled the Output switched ON url action stops working. didnt expect this, but looks like there is some relation ?
