I have created a weather sensor which has hum, temp, baro, predicition and lux.
Aslo i have attached there another ds temp sensor (for node internal temp).
Problem is that when i update fw over ota or reboot node, it'll occasionally detect sensors all mixed up:
temp/hum, temp, baro/temp/hum etc... Also when it does that, not all the data will be updated on combined sensros.
Is there a way to present the sensors to domticz so, that it recognises 1 combined weather sensor and then others.
I have tried with all different Sensor ID's 1-4, lux id5 and internal temp id6.
Also tried with giving same sensor ID number to hum, temp, baro and predicition.
Domoticz detects it as a combined sensor, but it doesn't update all values after initial value has been sent.
If i monitor the data on myscontroller, all the variables are updating on the node.

Hi,
i have similar problem with domoticz and mysensors.
Firstly, i can't get current dim level from domoticz on startup.
Secondly if i start arduino and controll it over domoticz only, dimming and on/off works. If i turn the rotary knob, domoticz commands won't work.
In serial monitor i see that new dim value has been received:

    Serial.print("Fading level: ");
    Serial.println(dimValue);

but output doesn't change. If i turn knob on rotary, value in domoticz changes.
I removed eeprom writes and rotary button. Only dims to off/on or domoticz commands off/on.

@pjr said in Presenting and controlling variables in domoticz:

Cannot get the point what you exactly mean but I think you should check for what child the message is for:
if(message.sensor == CHILD_ID_aeg2** && message.type == ...) { ..do suff.. }

Thank you, message.sensor was the thing i needed. Browsed cpp and h files in mysensors library and googled, but couldn't find variables to use with message.*.

I cannot use multiple V_PERCENTAGE values. Because if a change a value in domo, both are changing (dime delay(aeg2)) and RGB dimmer..

Hello,

having trouble controling multiple actuators in domoticz.
I have made arduino sketch with preloaded setpoints for outside light controlling, in case domoticz is offline or unreachable after power outage etc.
I have switch on/off setpoints and time delay for switch off

When i activate present(RGB_RGBChild, S_RGB_LIGHT, "Ees RGB valik") then also time-delay is automatically adjusted by it.

MyMessage msgTe1(CHILD_ID_Te1, V_TEMP);
MyMessage msgSp21(CHILD_ID_Sp21, V_HVAC_SETPOINT_HEAT);         //seadearvu muutmine kaugelt
MyMessage msgSp22(CHILD_ID_Sp22, V_HVAC_SETPOINT_COOL);
MyMessage msgvalgus(CHILD_ID_valgus, V_LEVEL);
MyMessage msgaeg2(CHILD_ID_aeg2, V_PERCENTAGE);

void presentation()  {
  sendSketchInfo("Valgus", "1.0");  // seadme nimi, versioon domoticzile
  present(CHILD_ID_Te1, S_TEMP, "Pooningul");        //anname anduri id, liigi, nime domoticzile
  present(CHILD_ID_valgus, S_LIGHT_LEVEL, "Valgustugevus"); //current level lux
  present(CHILD_ID_Sp21, S_LIGHT_LEVEL, "Valgus sisse"); // light on
  present(CHILD_ID_Sp22, S_LIGHT_LEVEL, "Valgus valja"); // light off
  present(CHILD_ID_aeg2, S_DIMMER, "Valguse viide valja");  // time delay off 

When i added ws2812 RGB switch everything got mixed up, especially time delay feature, but also switching in domoticz activated CHILD_ID_Sp21 and CHILD_ID_Sp22(no values were changed)

MyMessage msgTe1(CHILD_ID_Te1, V_TEMP);
MyMessage msgSp21(CHILD_ID_Sp21, V_HVAC_SETPOINT_HEAT);         //seadearvu muutmine kaugelt
MyMessage msgSp22(CHILD_ID_Sp22, V_HVAC_SETPOINT_COOL);
MyMessage msgvalgus(CHILD_ID_valgus, V_LEVEL);
MyMessage msgaeg2(CHILD_ID_aeg2, V_PERCENTAGE);



MyMessage lightRGBMsg(RGB_LightChild,  V_RGB);        // standard messages, light
  MyMessage lightdimmerMsG(RGB_LightChild ,V_DIMMER); 
MyMessage lightOnOffMessage(RGB_LightChild, V_STATUS);

void presentation()  {
  sendSketchInfo("Valgus", "1.0");  // seadme nimi, versioon domoticzile
  present(CHILD_ID_Te1, S_TEMP, "Pooningul");        //anname anduri id, liigi, nime domoticzile
  present(CHILD_ID_valgus, S_LIGHT_LEVEL, "Valgustugevus"); //current level lux
  present(CHILD_ID_Sp21, S_LIGHT_LEVEL, "Valgus sisse"); // light on
  present(CHILD_ID_Sp22, S_LIGHT_LEVEL, "Valgus valja"); // light off
  present(CHILD_ID_aeg2, S_DIMMER, "Valguse viide valja");  // time delay off 

  present(RGB_RGBChild, S_RGB_LIGHT, "Ees RGB valik");// present to controller
  present(RGB_LightChild, S_LIGHT, "Ees on/off/dim ");
  present(RGB_SolidColorChild, S_LIGHT, "Ees on/off värv" );
  present(RGB_TextColorChild, S_INFO, "Ees värvi tekst" );  
  present(RGB_AlarmPatternChild, S_BINARY, "Ees vilkuv pu/va" );
  present(RGB_NextPatternChild, S_DIMMER, "Ees RGB muster" );

Each child is presented in domoticz correctly with correct name.
Is there even a way to use multiple same type actuators in a sketch?

To update preloaded setpoints from arduino to domoticz, i have this added (which might be the problem?)

void receive(const MyMessage &message) {

  if (message.type == V_HVAC_SETPOINT_HEAT) {
    Sp21 = message.getFloat();
  }
  if (message.type == V_HVAC_SETPOINT_COOL) {
    Sp22 = message.getFloat();
  }

  if (message.type == V_PERCENTAGE) {
    aeg2 = message.getFloat();
  }
  sendNewStateToGateway();

and

void sendNewStateToGateway() {

  send(msgSp21.set(Sp21));
  send(msgSp22.set(Sp22));
  send(msgaeg2.set(aeg2));

}

Have googled and searched mysensors/domoticz forums but no results. I'm more like hobby programmer if that's the word and self somewhat learned by google for a few years now.
