Actually, I needed to change 2 things: first one was dividing by 1000.0 rather than 1000 and the other one was calling send(msgVcc.set(Vcc, 2)); rather than send(msgVcc.set(Vcc)); Now the log reads 2.95V.

Thanks Mikael (@mfalkvidd) & everyone! Happy coding!

Yes Mikael, but it suddenly hit me that you have to allow Domoticz to add new devices from the console. I can see the Temperature and the Humidity now!

Thanks again!

Thanks for your reply!

It appears to be a newby mistake: I overpowered the NRF24L01 radios: the FTDI board did put out 5.0V although the output Voltage selectors witch wat at the 3.3V position..

Another lesson learned today... always doublecheck !

@martinb Did you replace the NRF24L01 with another NRF24L01? iow was it a bad device?

@mfalkvidd Interesting discussion!

I've got the same issue with a lux sensor based upon BH1750; battery life is limited to 7-10 days (3V, 9900mAh)
I gather that it's not possible to use the interrupt method in this case?

Do you have any suggestions how I can improve battery life?

Hi Zboblamont,

Thanks for your response, but the error occurs in the line, obviously because Vcc is of the type 'float'

send(msgVcc.set(Vcc));

Hi,

I really enjoy using MySensors!

Got a small general question though: I'm using a BH1750 light sensor, powered by a 3V battery and I'd like to keep an eye on the battery status.

I have added a line to the existing BH1750 scetch:

#define CHILD_ID_VCC = 1
MyMessage msgVcc(CHILD_ID_VCC, V_VOLTAGE);
.. 
void Presentation() {
  sendSketchInfo("Light Lux Sensor", "1.1");
  present(CHILD_ID_LIGHT, S_LIGHT_LEVEL);
  present(CHILD_ID_VCC, S_MULTIMETER);
}

Loop() {
uint16_t lux = lightSensor.readLightLevel();
float Vcc = ReadVcc();

send(msgLux.set(Lux));
send(msgVcc.set(Vcc));
}

Domoticz recieves the data now, but the Voltage is reading 2968V because readVcc delivers mV
If I change the code to:

float Vcc = readVcc()/1000;

I get an error message "call of overloaded 'set(float&)'is ambiguous"
How can I send decimal values to the Domoticz controller from MySensors?

Hi,

Just got the MySensors Serial Gateway (Arduino Pro Mini (328) & NRF24L01) working with my first sensor (Arduino Pro Mini & NRF24L01 & DHT22). Running in DEBUG mode.
When debugging the Gateway, I can see the values:

..

0;255;3;0;9;198199 TSF:MSG:READ,1-1-0,s=1,c=1,t=0,pt=7,l=5,sg=0:21.7

From Domoticz, I can see the Gateway and the Child nodes. The values are also read.
However, no device is added..


Any suggestions?

Regards, Frank

Recompiled & uploaded the sektch and now I see the Temperature and Humidity values allright!
Thanks again!

Now that we have communication: if I run the (standard) DhtTemparatureAnd HumiditySensor sketch, the Setup() en Loop() never seem to run.. The Serial.println commands don't make it to the Serial monitor..

Am I missing something here?
