    • RE: Node with DS18B20 and DHT22

      Hi!

      It's to make a node for the 2nd floor of my house: 6 DS18B20 for bedrooms, office (?), stairs and 2 DHT22 for the 2 bathrooms.

      DHT22 are more expensive than DS18B20 and i need to know humidity only for the bathrooms.

      Ok so the number next to V_TEMP in the values column are groupID ?

      The problem in my DS18B20+DHT22 node is that they have all the same groupID, so domoticz group TEMP and HUM in the same device and the HUM of the 1st DHT22 is updated with the HUM of the 2nd one ...

      @hek
      No it's the #1 in the "Values" column

      On an other node with 4 DS18B20:
      0_1479066924561_Screenshot - 13112016 - 20:53:28.png

      The DS18B20 have different ID (#1, #2, #3 and #4)

    • RE: DS18B20 and DHT22 in the same sensor and sketch

      Hi !

      I've same problem to make a node with 2 DS18B20 and 2 DHT22.

      In domoticz the DS18B20 sensors are show with humidity value (of the 1st DHT22) and the 2nd DHT22 show the humidity value of the 1st one...

      The sketch i'm using is here: https://forum.mysensors.org/topic/5222/node-with-ds18b20-and-dht22

      (sorry for my bad english)

      And in domoticz all childs have the same ID (#1)
      0_1478106899752_Screenshot - 02112016 - 18:14:09.png

      Noboby have an idea of the problem ?

      [EDIT]
      And i just discover an other "problem": the 2nd DHT22 humidity value is updated with the value of the 1st one...

      Hi !

      Thank you for the greeting @mfalkvidd 🙂

      I've already read the discussion you've quote but i'm not sure to understand: some say "modify domoticz code" other say "present sensor after each other" ...

      Witch version of mysensors is needed to do what i try ? 2.0 or beta ?
      I'm using, perhaps it's not the good version ...

    • Node with DS18B20 and DHT22

      Hi!

      First sorry for my bad english 🙂

      I'm trying to make a node with 2 DS18B20 and 2 DHT22 but in domoticz the DS18B20 is show like "Temp + Humidity" sensors (with the humidity value of the 1st DHT22).

      I've read on github that it's possible to set "groupID" to resolve this problem, but i don't understand how to set this.

      I've try this, but not working:

        present(0, S_TEMP, "SENSOR1");
        present(1, S_TEMP, "SENSOR2");
        present(CHILD_ID_TEMP1, S_TEMP, "SENSOR3");
        present(CHILD_ID_HUM1, S_HUM, "SENSOR3");
        present(CHILD_ID_TEMP2, S_TEMP, "SENSOR4");
        present(CHILD_ID_HUM2, S_HUM, "SENSOR4");
      

      Does someone can explain me please ?

      Thank you.
