ah, thanks mfalkvidd, thats what i´m looking for!

It is working! ;D ...thank you very much!
Now i understand a little bit more with MySensors

thanks mfalkvidd and since!

now i´ve added the following to the onPulse function:

delay(150);
  if(digitalRead(DIGITAL_INPUT_SENSOR) == HIGH){
    Serial.println("onPulse called");
    pulseCount++; 
  }

now it is working, thanks for the support to all of you!

btw: is there a way to reset the volume value, without running the cleareeprom sketch, so that i can keep the sensors node id!?

I connected the sensor to D3 pin.

thx sundberg84 for your fast response.

meanwhile i added Serial.println("onPulse called"); before pulseCount++ in onPulse-function.
The Serial Monitor confirms, the above problem.

I turn on the water tap, till the position of my water counter wheel is exactly in position to trigger the RISING interrupt of the sensor, then i close the water tap. So the signal is constantly high. the serialmonitor prints, onPulse called, everything seems ok. after a while (seconds or minutes, tried both) i turn on the water tap again, till the position of the water counter wheel lets FALLING the signal from sensor, and turn of the water tap again. So signal is constantly low. In this moment the monitor prints also "onPulse called".

Due to the described behavior I do not think it is up to the interval time, or?

Hi,
I build up a WaterPulseMeterSensor as the original MySensors example:
Controller:Arduino nano
Sensor: TCRT5000 IR Barrier Line Track sensor
Powered with USB-powersupply.
Sketch: Original Sensor example sketch - only changed the Interrupt mode from "FALLING" to RISING", as you can see below.

      }
      flow = (60000000.0 /interval) / ppl;
    }
    lastBlink = newBlink;
  }
  pulseCount++; 
}

Here is what happens:
When DigitalSensorPIN is RISING, the onPulse function is called as expected, but when DigitalSensorPIN is FALLING, the onPulse function is called also, which should not happen, right!??
So this gives me a wrong consumption of 2liters per rotation, instead of 1liter.

Has someone any idea what is going wrong?

Hi,
i have build an water flow sensor and want to save the total flow value in mL in the eeprom.
Is there a way to use the saveState and loadState from MySensors v2.0? The value will grow a long number, so it´s not only a "state" like 0/1 from switch/relay.

Thanks and best regards,
vga

ok, thank you Yveaux for your help!
to understand the mechanism, when the sensor node starts to search for parent again, why doesn´t it find the parent node, which used before?

Ah, Thanks!

So, i have do i have to set the NODE_ID at Gateway to (i.e. 0), to have a fixed ID, to which i connect the sensor node, if i want it static, right?

yes, for testing without controller i set the NODE_ID manual, and now it works.
Transmit works now. But when sensor was out of range, transmit fails some times, and sensor comes back into range, the transmit doesn't works again.

i haven´t set a MY_NODE_ID, the myconfig is set to auto, so i thought this will set automatically. Or is this only, when gateway is connected to controller?

Hi,
i have worked with MySensors v1.5 till now, but i started to begin working with v2.0.

I have made a test SerialGateway (nearly example sketch) with an arduino nano, and a test sensor node with an arduino Pro Mini 3,3V.

When starting both arduinos, on the Sensor node i get the following output:

TSM:PDT
TSM:INIT
TSM:RADIO:OK

!TSM:FAILURE

What das that mean? (especially the "!TSM:CHKID_FAIL" and "...:FAILURE"
My Gateway is not connected to any controller, just want to check, if my Sensor node with the sensor hardware works (serial outputs) but the only thing i get is this.

Do i have to fully implement the mySensor Network, also the controller connection, or is there a way to test my Sensor node at first, then the communication with the gateway only, and at least put it on my controller?
