Not seeing child id 0 Humidity from DHT

[derksuh]

Hello all,

i made myself a sketch and uploaded it to a arduino nano.
I'm using pimatic and can find the temperature and the relay but i don't see the humidity.

This is the sketch.

#include <SPI.h>
#include <MySensor.h>
#include <DHT.h>

#define NODE_ID 5 // ID of node

//child ids
#define CHILD_ID_HUM 0
#define CHILD_ID_TEMP 1
#define CHILD_ID_VLIGHT0 2

//pin definitions
#define RELAY_PIN0 4
#define HUMIDITY_SENSOR_DIGITAL_PIN 3

//relay state
#define RELAY_ON 0
#define RELAY_OFF 1
#define NUMBER_OF_RELAYS 1

//sleep timer settings
unsigned long SLEEP_TIME = 1000; // Sleep time var, first read is 0
unsigned long SLEEP_TIME_POST = 60000; // Sleep time var changes to this value after
unsigned long LAST_SLEEP_TIME = millis(); // Sleep time between reads (in milliseconds)

bool state;

//mysensors setup
MySensor gw;
MyMessage msgHum(CHILD_ID_HUM, V_HUM);
MyMessage msgTemp(CHILD_ID_TEMP, V_TEMP);
MyMessage msgLSW0(CHILD_ID_VLIGHT0, V_LIGHT);

//dht setup
DHT dht;
float lastTemp;
float lastHum;
boolean metric = true;

void setup()
{
// Make sure relays are off when starting up
digitalWrite(RELAY_PIN0, RELAY_OFF);
// Then set relay pins in output mode
pinMode(RELAY_PIN0, OUTPUT);
dht.setup(HUMIDITY_SENSOR_DIGITAL_PIN);

// mysensor startup and Send the Sketch Version Information to the Gateway
gw.begin(incomingMessage, NODE_ID, true);
gw.sendSketchInfo("DHT&relay&button", "1.1");
// Register all sensors to gw (they will be created as child devices)
gw.present(CHILD_ID_HUM, S_HUM);
gw.present(CHILD_ID_TEMP, S_TEMP);
gw.present(CHILD_ID_VLIGHT0, S_LIGHT);
delay(1000);
metric = gw.getConfig().isMetric;
// Set relay to last known state (using eeprom storage)
state = gw.loadState(CHILD_ID_VLIGHT0);
digitalWrite(RELAY_PIN0, state?RELAY_ON:RELAY_OFF);
}

void loop()
{

 if (millis() - LAST_SLEEP_TIME > SLEEP_TIME) {   

dhtupdate();
LAST_SLEEP_TIME=millis();
if (SLEEP_TIME < SLEEP_TIME_POST) {
SLEEP_TIME=SLEEP_TIME_POST;
}

}

gw.process();

}

void incomingMessage(const MyMessage &message) {
// We only expect one type of message from controller. But we better check anyway.
if (message.isAck()) {
Serial.println("This is an ack from gateway");
}

if (message.type == V_LIGHT) {
if (message.sensor == CHILD_ID_VLIGHT0){
// Change relay state
digitalWrite(RELAY_PIN0, message.getBool()?RELAY_ON:RELAY_OFF);
// Store state in eeprom
gw.saveState(message.sensor, message.getBool());
// Write some debug info
Serial.print("Incoming change for relay1 sensor:");
Serial.print(message.sensor);
Serial.print(", New status: ");
Serial.println(message.getBool());
}
}
}

void dhtupdate() {
float temperature = dht.getTemperature();
if (isnan(temperature)) {
Serial.println("Failed reading temperature from DHT");
} else if (temperature != lastTemp) {
lastTemp = temperature;
if (!metric) {
temperature = dht.toFahrenheit(temperature);
}
gw.send(msgTemp.set(temperature, 1));
Serial.print("T: ");
Serial.println(temperature);
}

float humidity = dht.getHumidity();
if (isnan(humidity)) {
Serial.println("Failed reading humidity from DHT");
} else if (humidity != lastHum) {
lastHum = humidity;
gw.send(msgHum.set(humidity, 1));
Serial.print("H: ");
Serial.println(humidity);
}

}

Fixed it! i manually added the sensor in pimatic and now it works

@derksuh great work. Thanks for reporting back.
