List all MESH messages on a serial port

Connectivity BLE // NFC

Hello everyone,

I need your help to find a solution to my problem. I use a mesh network to measure the level of the water tank.

This mesh network is not connected to the internet
I have in each tank a xenon with a lidar sensor (9x)
I have many xenon to relay antennas
I have a xenon to transmit the MESH data on a raspberry through a USB port, this data is read with Node-Red.

But we are limited to 5 Mesh.subcrive. Do you know a trick so you can increase to 9?

Thank you in advance for your answers.
Christophe

You can use one subscribe for all events that start with a particular prefix
e.g. one subscribe for tankData_ will accept all of the following

tankData_Node1
tankData_Node2
tankData_Average
tankData_Max
tankData_Min
...

Inside the subscribe handler you can then check the suffix contained in name (first parameter) to distinguish between them.

This is what the docu means with that

And it’s my code. It’s working perfect. Thx you very much @ScruffR !

SYSTEM_THREAD(ENABLED);
SYSTEM_MODE(AUTOMATIC);

void setup() {
    Mesh.subscribe("G001_", Information);
    Serial.begin(9600);
}

void loop() {
}

void Information(const char *event, const char *data)
{
    if(strcmp(event, "G001_S001") == 0)
    {
        Serial.print(String(data));
    }
    else if(strcmp(event, "G001_S002") == 0)
    {
        Serial.print(String(data));
    }
    else if(strcmp(event, "G001_S003") == 0)
    {
        Serial.print("R"+String(data));
    }
    else if(strcmp(event, "G001_S004") == 0)
    {
        Serial.print("T"+String(data));
    }
    else if(strcmp(event, "G001_S005") == 0)
    {
        Serial.print("S"+String(data));
    }
}
