Might be helpful for somebody... Things configuration for OpenHab2:

Bridge mysensors:bridge-eth:gateway_2 [ ipAddress="192.168.178.50", tcpPort=5003, sendDelay=200, enableNetworkSanCheck=true ] {
        /** define things connected to that bridge here */
        light sonoff01 [ nodeId="0", childId="0", requestAck=true ]
}

Cool! What is the consumption of the node and how long batteries last?

Thank you guys for prompt reaction. Indeed, Ethernet GW works flawlessly!

@gohan I'm sorry, MQTT is not supported by OpenHab MySensors binding. Ethernet Gateway is not supported on Raspberry PI.

Hello Masters,

Could you please help me with setting up virtual serial port?

I can't see the interface created under /dev.
I'm using the instructions and finish with the setup with the following command:

pi@raspberrypi:/tmp/MySensors $ ./configure --my-gateway=serial --my-serial-is-pty --my-serial-pty=/dev/ttyMySensorsGateway
[SECTION] Detecting target machine.
  [OK] machine detected: SoC=BCM2836, Type=Rpi2, CPU=armv7l.
[SECTION] Detecting SPI driver.
  [OK] SPI driver detected:BCM.
[SECTION] Detecting init system.
  [OK] init system detected: systemd.
[SECTION] Saving configuration.
[SECTION] Cleaning previous builds.
[OK] Finished.

pi@raspberrypi:/ $ sudo /usr/local/bin/mysgw -d
mysgw: Starting gateway...
mysgw: Protocol version - 2.1.1
mysgw: MCO:BGN:INIT GW,CP=RNNG---,VER=2.1.1
mysgw: TSF:LRT:OK
mysgw: TSM:INIT
mysgw: TSF:WUR:MS=0
mysgw: TSM:INIT:TSP OK
mysgw: TSM:INIT:GW MODE
mysgw: TSM:READY:ID=0,PAR=0,DIS=0
mysgw: MCO:REG:NOT NEEDED
mysgw: Listening for connections on 0.0.0.0:5003
mysgw: MCO:BGN:STP
mysgw: MCO:BGN:INIT OK,TSP=1

Everything seems to be OK. However, when I check /dev directory, the interface is not created.

What could be an issue?
Thank you in advacne!

The problem was faulty NRF24... another batch :(
Just powered sensor in sleep mode is consuming as expected - a few uA.
But later, after while, power consumption is increasing.
Commenting Vcc was just coincidence.

Received new NRFs batch from mysensors shop, and all the problems gone.
Thanks!

I'm not sure if it's related to DHT22, because sleep mode works fine when Vcc function is commented in the sketch.

Hello,

I'm made temp/hum sensor with slim node and DHT22.
When Mysensors/HumiditySensor sketch is loaded, the sensor in sleep mode consumes 25uA.

I also would like to report battery level.
But when read vcc function is included in the sketch, the power consumtions after transmission remains ~ 0.1 - 0.2mA.

Any ideas why sleep mode is not functioning correctly with sendBatteryReport()?
Thank you in advance.

Please see my updated sketch:

#include <SPI.h>
#include <MySensor.h>  
#include <DHT.h>
#include <Vcc.h>

#define VCC_MIN 2.8
#define VCC_MAX 3.3
Vcc vcc;
#define NODE_ID 2

#define CHILD_ID_HUM 0
#define CHILD_ID_TEMP 1
#define HUMIDITY_SENSOR_DIGITAL_PIN 3
unsigned long SLEEP_TIME = 120000; // Sleep time between reads (in milliseconds)

MySensor gw;
DHT dht;
float lastTemp;
float lastHum;
boolean metric = true; 
MyMessage msgHum(CHILD_ID_HUM, V_HUM);
MyMessage msgTemp(CHILD_ID_TEMP, V_TEMP);


void setup()  
{ 
  gw.begin(NULL, NODE_ID);
  dht.setup(HUMIDITY_SENSOR_DIGITAL_PIN); 

  // Send the Sketch Version Information to the Gateway
  gw.sendSketchInfo("Humidity", "1.0");

  // Register all sensors to gw (they will be created as child devices)
  gw.present(CHILD_ID_HUM, S_HUM);
  gw.present(CHILD_ID_TEMP, S_TEMP);
  
  metric = gw.getConfig().isMetric;
}

void loop()      
{  
  sendBatteryReport();
  delay(dht.getMinimumSamplingPeriod());

  float temperature = dht.getTemperature();
  if (isnan(temperature)) {
      Serial.println("Failed reading temperature from DHT");
  } else if (temperature != lastTemp) {
    lastTemp = temperature;
    if (!metric) {
      temperature = dht.toFahrenheit(temperature);
    }
    gw.send(msgTemp.set(temperature, 1));
    Serial.print("T: ");
    Serial.println(temperature);
  }
  
  float humidity = dht.getHumidity();
  if (isnan(humidity)) {
      Serial.println("Failed reading humidity from DHT");
  } else if (humidity != lastHum) {
      lastHum = humidity;
      gw.send(msgHum.set(humidity, 1));

      Serial.print("H: ");
      Serial.println(humidity);
  }

  gw.sleep(SLEEP_TIME); //sleep a bit
}

void sendBatteryReport() {
          float p = vcc.Read_Perc(VCC_MIN, VCC_MAX, true);
          int batteryPcnt = static_cast<int>(p);
          gw.sendBatteryLevel(batteryPcnt);
}

My problem was defected NRF24 radios. Had to order 3rd batch from ebay, and even though it contained a few defected modules.

Hello guys,

I'm reading your post, and that is amazing... you're fighting with u/nAmps.
However, I'm concerned about mAmps :)

The lowest what I can get with Atmega328 + NRF24 on breadboard is 1mA.

What I've done:
Flashed Atmega328p with ATmegaBOOT_168_atmega328_pro_8MHz.hex
Uploaded BinarySwithchSleepSensor sketch with FDTI. Tried: API 1.4/1.5, IDE 1.0.6/1.6.5 (no difference)
Powered the sensor directly with 2xAA
Changed ext fuses to x07 (no BOD)
Connected NRF24 according to MySensors instructions

On the breadboard I have only:
Atmega328p
NRF24
10k resistor on 1st/reset pin.

With this set up minimum what I can get is:
Atmega328p w/o NRF - 3pin con - 0.1mA /not con - 3.4mA
Atmega328p with NRF - 3pin con - 1.09mA /not con - 1mA

I'm using cheap multi-meter, however, with Gammon's J sketch - it shows 3uA without NRF.

I'm struggling almost a week, and can't understand, why you guys achieving such a great results while using almost the same setup (Mini 8Mhz is based on Atmega328p).

Your ideas and suggestions are most welcome. Thank you in advance!

Hello,

I have made this gateway with W5100.
Everything looks OK, except random connection failures.
Clients - MyMQTT (android), Openhab are loosing contact with the broker time after time.
The issue can occur every 5 - 60 mins.

Any ideas what could be the problem?

Thank you in advance.
