P1 not working when using Mysensors ?

[Toine33]

Hey guys,

I am trying to make this sketch work for a few days now but it looks like it wont work in combination with Mysensors.
Here the sketch without the Mysensors.
I am receiving output of the P1 Port on hardware serial 2.

#define MY_DEBUG

//#define MY_RADIO_RF24
//#include <MySensors.h>



char c;
 
void setup() {
 Serial.begin(19200);
  Serial2.begin(9600, SERIAL_7N1);
}
 
void loop() {
    if (Serial2.available()) {
        c = Serial2.read();

    Serial.print(c);
    }
}

When i am using this same sketch with the Mysensors it is not giving output anymore.
Does someone has an clue ?
I have used an Arduino nano 16mhz first on altsoftserial with the same result.
in this example i am using an Arduino mega 2560.

#define MY_DEBUG

#define MY_RADIO_RF24
#include <MySensors.h>



char c;
 
void setup() {
 Serial.begin(19200);
  Serial2.begin(9600, SERIAL_7N1);
}
 
void loop() {
    if (Serial2.available()) {
        c = Serial2.read();

    Serial.print(c);
    }
}

Welcome to the mysensors community @toine33

What does the debug output from the node say?

Are you sure the nrf24 is correctly wired? Is your gateway and controller up and running?

If you haven't already, see https://forum.mysensors.org/topic/666/debug-faq-and-how-ask-for-help/ for the most common problems and how to troubleshoot them efficiently.

[Toine33]

So the output wich is given on the first sketch is :

/ISk5\2MT382-1003

0-0:96.1.1(5A424556303035303738373110323132)
1-0:1.8.1(08316.297*kWh)
1-0:1.8.2(08472.574*kWh)
1-0:2.8.1(00000.020*kWh)
1-0:2.8.2(00000.010*kWh)
0-0:96.14.0(0001)
1-0:1.7.0(0000.38*kW)
1-0:2.7.0(0000.00*kW)
0-0:17.0.0(0999.00*kW)
0-0:96.3.10(1)
0-0:96.13.1()
0-0:96.13.0()
0-1:24.1.0(3)
0-1:96.1.0(3238303131303031323031113336343132)
0-1:24.3.0(190907210000)(00)(60)(1)(0-1:24.2.1)(m3)
(04212.860)
0-1:24.4.0(1)
!

You can see here the output of my energy meter wich is given every 10 seconds

And this is the output when i am using the sketch with Mysensors,
It is curently not connected because im am unable at the moment.
The strange part is that the serial prints are not workig at this stage anymore or is this normal when using mysensors?

P.S
I have done some testing also on RS485 and had the same situation.

[mfalkvidd]

@toine33 yes this is normal. MySensors is unable to initialize the radio so it never reaches setup, nor loop.

[electrik]

You expect the baudrate to be 19200, but Mysensors also initialises the port at a baudrate. Maybe that one is done later and you should use the terminal on that baudrate?

[Toine33]

Hey guys,
Thanks for helping :) . The sketch was working after i have deleted the Serial.begin in the void setup.

void setup() {
Serial.begin(19200);

i only have some other issues at the moment haha,
The value's from the gas meter / high an low elecktricity are showing wrong within Domoticz

When i am doing /1000 on the send values of the GAS meter and elecktricity meters i am getting an beter value but i loose 3 decimals and cant see any calculated value by domoticz.
Is there an option to send these decimals ?

Thanks !

Nice work @toine33
Use set(value, numberOfDecimals)

Example:

send(msgWatt.set(mEAV, 3));

Documentation: https://www.mysensors.org/apidocs/MyMessage_8h.html#a8af6ca9ee9a61b5954e405a2ae7de361

[Toine33]

@mfalkvidd
Sorry for asking , but as you already noticed i am not super familiar to the arduino coding haha.

So i have tried send(msgWatt.set(mEAV, 3));
But the only output i am receiving is something like this,

TSF:MSG:SEND,3-3-0-0,s=3,c=1,t=35,pt=7,l=5,sg=0,ft=0,st=OK:4213752.000

What i would like to archieve is an value like
TSF:MSG:SEND,3-3-0-0,s=3,c=1,t=35,pt=7,l=5,sg=0,ft=0,st=OK:4213.752

I just would like to ad an decimal somehow and send this to Domoticz.

[mfalkvidd]

@toine33 asking is exactly what the forum is here for :)
This should work (note: .0 is a "trick" to let the compiler know we want a floating point / decimal number)

send(msgWatt.set(mEAV / 1000.0, 3));

[Toine33]

And here an picture how it is showing up in domoticz:
