Mysensors "Global" message

Hi all, how can i send (is possible?)transparently a global message (like "set on board led ON" )from a node to all other nodes without to add seperate "set" commands for all nodes? (another newbie :) ) .

By using a for loop and iterate over the nodes (1-255 possible) and send it one by one.

Thanks for the response @boozz , but... i have i my mind something such as ... all nodes react to a message with its ID(default) and to this "global type" message... something like a "system channel" with special comands like "who is listening"? or "everyone switch to mode "x" . Any idea?

@tekka is playing with a new broadcast implementation which would allow you to do this type of things.

(the problem here is to avoid a broadcast mess where repeaters re-send things endlessly)

@hek thanks for the response i will try to figure out @tekka 's broadcast implementation... i would appreciate a guideline from @tekka!

Hi there !
I know this thread is almost one year old, but I haven't found any recent thread about broadcast messages.

Is there a way to broadcast messages ?
My switchs are meant to drive groups of light.
Instead of sending multiple messages, each switch could broadcast a message which each light could intercept, check if the "group id" is the correct one, and turn on ;)

Hi, @napo7, still have the same question! The only thing that i have done till now is... to send a message to set.Destination(255) that is being handled from gateway as a normal message, but althought is visible to serial output all other nodes, wasn't able to handle it! (do not forget that i am new to this). is there any idea how to retrieve the payload from this kind of "INTERNAL" message?
