2nd sensor in sketch not showing up in HA

[mrhutchinsonmn]

I am trying to modify my working moisture sensor sketch to present 2 child Ids instead of one. Arduino serial monitor shows the data from both sensors and HA sees it but the 2nd sensor does not show up in unused entities. I am confident I am erring in my sketch somehow but not sure where.

/*
  AnalogReadSerial

  Reads an analog input on pin 0, prints the result to the Serial Monitor.
  Graphical representation is available using Serial Plotter (Tools > Serial Plotter menu).
  Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.

  This example code is in the public domain.

HA logs:

@mrhutchinsonmn I think the error indicates the child already exist, so you could try to change the node id, or modify the persistence file manually:

@mrhutchinsonmn said in 2nd sensor in sketch not showing up in HA:

MyMessage msg(CHILD_ID_A0, V_LEVEL);
MyMessage msg2(CHILD_ID_A1, V_LEVEL);

void loop() {
  [...]
  send(msg.set(sensorValue));
  send(msg.set(sensorValueA1));
   [...]
}

You are sending both sensor values with the same message, so they both get reported to child ID 0 and child ID 1 will never show up.

Change the second send function from
send(msg.set(sensorValueA1));
to
send(msg2.set(sensorValueA1));

@BearWithBeard You beat me to it by a minute! ;)

send(msg2.set(sensorValueA1));

Yes, that was it!! Thank you!!
