    @waynehead99 you most likely need 1.4 Lib for the new sleep constructor. I have not used sleep on 1.3 so I do not remember what arguments you had available there.
    I have also extended sleep with an additional constructor which @hek has pulled into the release branch of 1.4 that permits you to use two external interrupts with independent triggers for sleep in addition to a timeout. Great for nodes with multiple sensors that still run on battery.

    Do you feel secure today? No? Start requiring some signatures and feel better tomorrow ;)

      @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

        @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

              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

                              Hi, I'm interested. :-)
                              Or is this the latest version ?

                              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)
