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

It is not rocket science to get the openHAB running w/MQTT gateway, see for example my post with DS/Light/Relay in http://forum.mysensors.org/topic/115/implementing-multiple-sensors/60

But sure, it would be great to put a wiki with all sensor settings for openHAB together on one page. I needed to read/search for some days to put the knowledge together...

Example of the openhab screenshots on mobile https://github.com/pgo-sk/mysensors/wiki/Home-automation-using-mysensors-and-openHAB
There you see also the mapping of the sensor

@hek, @tbowmo and rest: ho ho guys, first think WAF, ie Wife Acceptance Factor

This variable has to be VERY high. Like: Darling, this whole fidling of mine would optimize our home and save on energy bills big time, so You can spend more on shopping craze. etc

Probably when I finish with testing, I start selling it to friends and we will have problem spending all of the money which suddenly comes our way. (Try here not to laugh )

@niccodemi Check:
gw.send(msgTemp.set(temperature, 1));
gw.send(msgHum.set(humidity, 1));
gw.send(msg.set(lux)); I miss here ",1"

@Hausner I send the temp changes only if change is > 1 deg C and light changes only > +/- 40 lux, have this in main loop:

void loop()     
{     
  // Process incoming messages (like config from server)
  gw.process(); 

  // Fetch temperatures from Dallas sensors
  sensors.requestTemperatures(); 

  // Read temperatures and send them to controller 
  for (int i=0; i<numSensors && i<MAX_ATTACHED_DS18B20; i++) {

    // Fetch and round temperature to one decimal
    float temperature = static_cast<float>(static_cast<int>((gw.getConfig().isMetric?sensors.getTempCByIndex(i):sensors.getTempFByIndex(i)) * 10.)) / 10.;

    // Only send data if temperature has changed more then 1 degC and no error
    if (int(lastTemperature[i]) != int(temperature) && temperature != -127.00) { //added integer

      // Send in the new temperature
      gw.send(msg.setSensor(i).set(temperature,1));
      lastTemperature[i]=temperature;
    }
  }
  // Read lux from TEMT6000
  float lightLevel = analogRead(LIGHT_SENSOR_ANALOG_PIN) * 9.765625;  // 1000/1024
  if (int(lightLevel - lastLightLevel) > 40 || int(lastLightLevel - lightLevel) > 40) {
      gw.send(msg.setSensor(CHILD_ID_LIGHT).set(int(lightLevel),1));
      lastLightLevel = lightLevel;
  }
  //gw.sleep(SLEEP_TIME); //no sleep for relays!!!!
}

Hope this helps, Pego

Do you use sleep in some of the nodes? I found with sleep(xxx) the messages get dropped across the mesh... I found that by making multiple sensors in one node - http://forum.mysensors.org/topic/115/implementing-multiple-sensors/59 and it gets worse with going through repeaters. For example the lux sensor could be very active and then the Relay ON/OFF messages get dropped... Interesting I did never see a temp or lux node message got dropped through the mesh.
EDIT I am using MQTT broker gateway and open HAB, but will probably switch to MQTT client gateway<->mosquitto<->openHAB to check whether the message delivery gets more stable.

Hi, happens to me w/MQTT gateway and OpenHAB too w/1.4 Mostly at midnight, but sometimes through the day too. After restaring the GW and/or sensors, the Sketch names/last updates are there.

@ntruchsess Good job, I had to do this to WIZ5200 too, although it has bigger buffers/supports more client connections. Same situation for Iboard PRO (with onboard NET, I think 5100)

@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.

@Dany said:

I would like to use with 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.

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

test1.items
test1.sitemap
test1.rules

My Current openHAB items/sitemap. 1 multisensor with Temp/Lux/Humidity sensor, 1 ethernet/MQTT gateway.

Also weather forcast from yr.no and Samsung TV remote controls (Mute working, rest not so much)
