@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?

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!

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?

Regards, Frank

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!

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:

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?

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 !

Hi,

Being new to Sensors, I have build my first serial gateway (Aruino Pro Mini (328P 3.3V) & NRF24L01) according to the instruction video on this site. The gateway seems to be working according to the debug log; my controller (Domoticz) also 'sees' the gateway.

However, when I fire up a (DHT22) client, it does not see the Gateway.

I use 47uF capacitors, the gateway and client are 1-5m apart. I tried seperate power supply..

Any suggestions?
Is there any way I can test if the Gateway is working?
