    @Mountainman ;

    Im trying your code and its almost what im looking for.
    I have two questions about it:
    1 : Is it possible that the battery info has is own child id?
    2 : Why dont you implement a light sensor like an LDR?

    I think that including LDR/light then you have the ideal multisensor ; light + temp/hum + motion + batt monitoring !
    But for now im playing with your code and try to implement light.

      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;

      MyMessage msgTemp(CHILD_ID_TEMP, V_TEMP);
      // Initialize motion message
      MyMessage msg(CHILD_ID_MOTION, V_TRIPPED);

      @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

            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.

                                  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.
