Hello All,
Long time reader, first time poster.
I've been building my-sensors in combo with Domoticz for a while now , and this project is one of my favorites.
I can confirm that the fritzing schema is correct, i checked it against the one i build. (whish i had the schema earlier, it would have been so much easier ;-))
I used the followin library from Rob Tillaart for the DHT22 (http://playground.arduino.cc/Main/DHTLib / https://github.com/RobTillaart/Arduino/tree/master/libraries/DHTlib) because the standard was not working...
Change line 37 to dht DHT;
comment out line 51
From line 78 i changed the code to this :

delay(2000);
      int chk = DHT.read22(HUMIDITY_SENSOR_DIGITAL_PIN);
      temp = DHT.temperature;
             //Serial.print("Temperature DHT :");
             //Serial.println(temp);
      if (isnan(temp)) {
          lastTemp = -1;
      } else if (temp != lastTemp) {
        lastTemp = temp;
        if (!metric) {
          temp = temp * 1.8 + 32.0;
        }
        gw.send(msgTemp.set(temp, 1));
        }
      hum = DHT.humidity;
      if (isnan(hum)) {
          lastHum = -1;
      } else if (hum != lastHum) {
          lastHum = hum;
          gw.send(msgHum.set(hum, 1));
      }

And it is working like a charm.
Now i ordered one of these : Wind Sensor
I want to trie to get it working with this build.
And indeed the lamp is stil available Solar Lamp

Hope this helps,
With Regard's
Peer

Thank's for the answers to this problem.
They didn't work for me, but i think i solved mine.
Stop monitoring the serial port for data from a terminal session.
See my post at Domoticz forum.

Hello,
I know this is an old post.
But i am trying the script getting to work in combination with Domoticz.
A did a little rebuild to 2.1.0, and i am getting a RGD light which i can switch to dimmable in Domoticz.
I can select color and dim the strip but i am struggeling with the Speed (V_VAR2) and Mode (V_VAR1).
How can I adress these two in Domoticz so it is picked up by the node?
So i want to set the mode and or the speed from Domoticz to.

Hello, i have looked arround but i cant seem to find any examples.
I want to dim 3 x 12v AC ledbulbs in my kitchen seiling, and i was wondering how to build one with Mysensor controll.
So input is 12v AC, wich should feed the mysensor node (converting ac-> dc) and dim my 12V AC led bulbs.
Any suggestions on this ?

Sure, no problem.
But it is not 100% clean, i am just a coppier and paste'r....
If you can clean it up that would be nice.

@Jan-Gatzke
Thank you, i see it in the code now ...
I tested it with setting the RGB levels one by one to 255, and this works, so the channels are responding to the initialisation code.
And because it is rebuild to version 2.0, i forgot one void to adjust...
void incomingMessage(
should be
void receive(

Problem solved, thank you very much.

A little question, the v1.3 is this the one with the corrected mosfet placement ?
I build and programmed one now, but i only get a bright white light, and no response when i switch the node. So now i am in doubt...

With regards
Peer

I have the same problem, i posted a question at the Domoticz Forum :
Not reconnecting serial portt

Greetz Peer

@Jan-Gatzke
Thank you for your post.
I hope the Mosfet's are comming in today, then i can build it up and play with it.

@Jan-Gatzke
Hi can you please post your adjusted sketch for further reference?

Just got the v1.3 pcb's from OSH Park, just waiting for some components, and the we go. It will be an exciting christmas
