Pulse power meter flooding gateway

Cliff Karlsson

I have built the pulse power meter using the code on this page and it is working great, but when I look at the domoticz log it looks like the sensor is flooding the controller with values.

Strange. I have the same setup and it works. What did you set the sleep time to in the sketch ? I'm changed to 15 minutes.

What is the cause of this problem?

What sensor are you using to count the pulses? The signal might need denouncing...

Cliff Karlsson

I am using the same sensor as in the build example, the biggest sensor.

sundberg84

And the code is unchanged from the website?

Cliff Karlsson

Damn, I removed the sensor and re-uploaded the original sketch and now I get the same error as I struggled with for several days. I get no values from the sensor and it is reported 3 times after every power-cycle.

 * DESCRIPTION
 * This sketch provides an example how to implement a distance sensor using HC-SR04 
 * Use this sensor to measure KWH and Watt of your house meeter
 * You need to set the correct pulsefactor of your meeter (blinks per KWH).
 * The sensor starts by fetching current KWH value from gateway.
 * Reports both KWH and Watt back to gateway.
 *
 * Unfortunately millis() won't increment when the Arduino is in 
 * sleepmode. So we cannot make this sensor sleep if we also want 
 * to calculate/report watt-number.

I cant see anything strange with the code - but i dont know that RFM69 stuff... the code should not send presentation three times, so can it be something with your radio?

Cliff Karlsson

Ahhh, got it to work again finally. I straightened the curled RFM69 antenna in desperation and moved it around in the room where I have the meeter. Could it be interference as I got alot of cables and electric stuff around the sensor and also a big ass thick pipe that is placed right next to the sensor and is located between the sensor and gateway?

Now I get this instead:

The most of the time the sensor sends twice every time, could it still be the pipe or other things that bounches the signal? Or would the pipe not affect the radio in that way.

And by 'biggest sensor' you mean the 'LM393 Light Sensor' ?

I use a comparable sensor (same pcb) with a LDR and had to debounce its readings or multiple pulses were detected on each blink.
Anyway, from the sketch I see sensor values should only be sent every 30 seconds, so that can't cause you gateway-spamming issue.

The sketch will try to receive the old absolute counter value on startup, so it can continue counting where it left off:

  // Fetch last known pulse count value from gw
  gw.request(CHILD_ID, V_VAR1);

IKf it doesn't get an answer, it will retry forever:

  } else if (sendTime && !pcReceived) {
    // No count received. Try requesting it again
    gw.request(CHILD_ID, V_VAR1);
    lastSend=now;
  }

Could it be that that mechanism is bugging you?
You could also connect to the sensor's serial port an see what it has to tell you.
