    Here is a version I'm currently using that makes use of interrupts so might be more suitable for a battery driven DHT/Motion multi sensor. It also includes the battery monitoring. Any feedback or improvements would be appreciated.

    #include <SPI.h>
    #include <MySensor.h>
    #include <DHT.h>
    
    #define CHILD_ID_HUM 0
    #define CHILD_ID_TEMP 1
    #define CHILD_ID_MOTION 2   // Id of the sensor child
    
    #define HUMIDITY_SENSOR_DIGITAL_PIN 4
    #define DIGITAL_INPUT_SENSOR 3   // The digital input you attached your motion sensor.  (Only 2 and 3 generates interrupt!)
    #define INTERRUPT DIGITAL_INPUT_SENSOR-2 // Usually the interrupt = pin -2 (on uno/nano anyway)
    
    unsigned long SLEEP_TIME = F; // Sleep time between reports (in milliseconds)
    
    
    int BATTERY_SENSE_PIN = A0;  // select the input pin for the battery sense point
    int oldValue=-1;
    
    MySensor gw;
    DHT dht;
    float lastTemp;
    float lastHum;
    boolean metric = false;
    
    int oldBatteryPcnt = 0;
    int battLoop =0;
    
    MyMessage msgHum(CHILD_ID_HUM, V_HUM);
    MyMessage msgTemp(CHILD_ID_TEMP, V_TEMP);
    // Initialize motion message
    MyMessage msg(CHILD_ID_MOTION, V_TRIPPED);
    
    boolean pinTriggered=0;//waitTime is number of seconds to hol in while loop
    long lastDebounceTime = 0;  // the last time the output pin was toggled
    long debounceDelay = 50;    // the debounce time; increase if the output flickers

    @mountainman Is there any instructions on how to wire/setup the hardware to work with your code?

      @egbertje;

      The battery percentage is associated with the parent Arduino Node in the vera UI.
      I have some LDRs ordered from Ebay so that is the next step. I had previously used the BH1750 I2C sensor in a multi sensor with the 1.3 lib but I want to debug on its own as it seemed to be giving unexpected readings.

      @codenea The instructions are pretty much from the main page although if I get a chance I try to draw it up and post some pics. My setup not very pretty yet with perf board and jumper wires. A dedicated PCB would be nice.

        Hello,

        Here is my combo to make a Home Monitoring solution:
        https://github.com/empierre/arduino/blob/master/MQv01dgi_1_4.ino

        It includes (currently on a Mega):

        • Barometer : BMP085
        • Temperature + Humidity DHT11
        • Particle sensor
        • Gas sensors MQ2 MQ6 MQ131 MQ135 TGS2600 2SH12

        To be added when stabilized:

        • Sound level in DB

        Could be added:

        • Light sensor
        • Vibration sensor
        • PIR

        z-wave - Vera -&gt; Domoticz
        rfx - Domoticz &lt;- MyDomoAtHome &lt;- Imperihome
        mysensors -&gt; mysensors-gw -&gt; Domoticz

          Hi guys,

          this is a one node with publishing DS temperatures and listening for relay commands I finished and tested yesterday>
          https://github.com/pgo-sk/mysensors/blob/master/arduino/DS_and_Relay.ino
          feel free to comment/use/publish...

          I combined the Dalas and Relay examples together - you have to deactivate the sleep for the relays to listen 100% of time.
          MQTT identification on openHAB:
          MyMQTT/20/0/V_TEMP - DS sensor(s)
          MyMQTT/20/1/V_LIGHT - relay 1
          MyMQTT/20/2/V_LIGHT - relay 2

          If somebody is interested I can post the maps/items files for openHAB

          Regards,
          Pego
          PS I am working on an home automation system with solar hot air panels control/solar hot water panels and all the common stuff like lights/temperatures/weather etc.. More here: https://github.com/pgo-sk/mysensors/wiki/Home-automation-using-mysensors-and-openHAB

                          Yes :), for the sketches mentioned earlier.

                                I could not decide yet on a platform. OpenHAB should be my next test.

                                It runs quit stable on my old WinXP64Pro Quadcore w/many virtual machines on it.
                                Have still some problems with the syntax of the openHAB settings, but else nice controller ;)

                                  @blacey I tried this already. This is a simple dimmer node, not RGB. It's work fine.
                                  But I would like to use a RGB colorpicker in openhab.

                                    I would do that soon too. Would you like to have a node only as rgbw dimmer or maybe with a lux sensor as I like to do to also adjust for constant light/lux in the room?

                                    In my menu you can see the setpoint for lux under the light sensor.

                                      @pgo The RGB Colorpicker works already in openhab.
                                      I have some problem in arduino side...i tried update the sample DimmerActuator code, but didn't work. I tried korttoma's code, but it didn't works for me, too.

                                      (e.g. message.header.childId -didn't work)

                                        Can you post the HW connections you use on arduino and the items/sitemap of the dimmer in openHAB? I can then check on my install.

                                          Has anyone made ​​RGB LED strip node? I am looking for a working example program ...

                                          I combined Humidity and Lux code. Serial monitor works ok (see below) but for some reason when I try to add node to Vera I get only node, temp and lux (no humidity). I guess something is wrong in combined sketch?
