This is good? i think is not, maybe someone can check?

@Tagore.PDE I don't think it's appropriate to post a sketch and ask if it's a good sketch. Please be more specific. Like do you have errors? Does something not work?

[Tagore.PDE]

Sorry about that, maybe the Controller ( Domoticz ) is not taking the soilmoisture correctly.
I see that he send 3 digits number, like this:

But domoticz show me like this:

So maybe is confused? or ai m confused?

[TheoL]

@Tagore.PDE I had a quick peak at your sketch. You're presenting the soil moisture sensor as a humidity sensor. That way Domoticz treats it as a humidity temp sensor.

If you want to be able to see the moisture level you could present it as a light level

  // Register all sensors to gateway (they will be created as child devices)
  gw.present(CHILD_ID_LIGHT, S_LIGHT_LEVEL);

But maybe @mfalkvidd has a better solution. Not sure what he uses for his office plant monitoring.

I just used the digitial output of the soil moisture sensor. Because I was only interested in the fact that my plants are thirsty.

Hope this helps.

[Tagore.PDE]

@TheoL thx for your feedback.

[Tagore.PDE]

For the record, to send in %, next code:

 int soilValue = analogRead(ANALOG_INPUT_SOIL_SENSOR); 
  soilValue = constrain(soilValue, 420, 1023); 
  soil = map(soilValue, 420, 1023, 100, 0);
  if (soil != lastSoilValue) {
    send(msgHumSoil.set(soil)); // Send in percent
    lastSoilValue = soil;```

[tlpeter]

I use V_LEVEL and S_MOISTURE for a moisture sensor.
The percentage part is something i am going to try for sure.

[Tagore.PDE]

Hi @tlpeter , cna share one example?

Regards.

[Tagore.PDE]

I think i get it, @tlpeter :

MyMessage msgHumSoil(SOILHUMDITY, V_LEVEL); 

void presentation()  {
  // Send the sketch version information to the gateway and Controller
  sendSketchInfo("Sensor POT", "1.1");
  wait(MESSAGEWAIT);

  // Register all sensors to gateway (they will be created as child devices)
  present(SOILHUMDITY, S_MOISTURE);
