Use another node than gateway for control

[boozz]

Hi all,

In a MySensors network a controller is connected with a gateway to read messages from sensor nodes and send messages to actuators.

In my MySensors network I use a serial gateway mainly for reading the messages and for the sake of simplicity I would like to keep it that way. (I use a labview application for logging purposes).

As my network grows I want to add some actuators, but I do not want to control them via the gateway as described before.

Would it be possible to send the control-messages around using another node than the gateway using serial communication? Or in other words: would it be possible to send messages in a similar way as would be done via the gateway but now using a dedicated node for that?

I read through the forum but could not find a real answer unfortunately

Best regards,

Boozz

@boozz messages can be addressed to any node. It is done like this:

message.setDestination(DESTINATION_NODE_ID);

For a practical example, see https://www.openhardware.io/view/53#tabs-source

Messages will still be routed through the gateway though.

hey thanks!

I didn't think of using message.destination... I used it in the past to have 2 nodes talking to each other. Now I need some code to get serial input translated to messages.

I think I know where I can find such code for that.

If that idea works I'll post the sketch.

@boozz Cool. What are you getting the serial input from? Is your actuator connected to serial?

@mfalkvidd
Serial input will come from a windows based PC. Probably the same as the one that acts as the datalogger.
The actuator could be any actuator-node.

To give you some more info:
I have some lights in my shed (mancave actually....:rolling_on_the_floor_laughing: ) that should turn on when pressing a button, somewhere nearby, i.e. near the door. This button is connected to a node that sends the command to the actuator node. setdestination will play a role in this node.
There's also an automation scheme to turn on (and more important: off) the lights. As the shed is quite far away it is very handy to turn off the lights when I have returned to my home and forgotten to turn of the lights (for whatever reason). For this purpose I will use this specific node. Once I manage to controll the lights in the shed, I will be able to controll some more things around.
