How To Send a command from Omega2+ to another via Network

  • Hi Everybody,
    I have one omega2+ with a sensor that will give +3.3v to GPIO.
    I have other 3 Omega2+ with relay expansion that are used to control Plugs using the relay.
    all 4 controllers are connected to the same WIFI network.

    how can I send command from the Master Controller (the one connected to the sensor) to switch on all the 3 relays on the other controllers via the network (when the sensor give +3.3v signal to GPIO)?

    Thank you in advance.

  • too much help in here, shifted to particle photon ...........
