    Somebody has good result in a working multisensor and wants to share his code?

    @egbertje Good Question :-) It would be nice to learn from existing working sketches..

      @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 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)

          @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.

                                      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.
