Hi,
I took your updated code for 2.0 and tried to add a relay.
The code looks like this:
#define MY_DEBUG
// Enable and select radio type attached
#define MY_RADIO_NRF24
//#define MY_RADIO_RFM69
#include <SPI.h>
#include <MySensors.h>
#include <DHT.h>
#define CHILD_ID_HUM 10
#define CHILD_ID_TEMP 11
#define CHILD_ID_MOT 12 //motion sensor
#define HUMIDITY_SENSOR_DIGITAL_PIN 4
#define DIGITAL_INPUT_SENSOR 3 // The digital input you attached your motion sensor. (Only 2 and 3 generates interrupt!)
#define RELAY_1 7 // Arduino Digital I/O pin number for first relay (second on pin+1 etc)
#define NUMBER_OF_RELAYS 1 // Total number of attached relays
#define CHILD_ID 5
#define RELAY_ON 1 // GPIO value to write to turn on attached relay
#define RELAY_OFF 0 // GPIO value to write to turn off attached relay
DHT dht;
float lastTemp;
float lastHum;
boolean metric = true;
unsigned long interval= 3000;//dht.getMinimumSamplingPeriod(); // the time we need to wait
unsigned long previousMillis=0; // millis() returns an unsigned long.
unsigned long SLEEP_TIME = 120000; // Sleep time between reports (in milliseconds)
MyMessage msgHum(CHILD_ID_HUM, V_HUM);
MyMessage msgTemp(CHILD_ID_TEMP, V_TEMP);
MyMessage msgMot(CHILD_ID_MOT, V_TRIPPED); //me
void before()
{
for (int sensor=1, pin=RELAY_1; sensor<=NUMBER_OF_RELAYS; sensor++, pin++) {
// Then set relay pins in output mode
pinMode(pin, OUTPUT);
// Set relay to last known state (using eeprom storage)
digitalWrite(pin, loadState(sensor)?RELAY_ON:RELAY_OFF);
}
}
void setup()
{
dht.setup(HUMIDITY_SENSOR_DIGITAL_PIN);
// metric = getConfig().isMetric;
pinMode(DIGITAL_INPUT_SENSOR, INPUT); // sets the motion sensor digital pin as input
}
void presentation()
{
// Send the Sketch Version Information to the Gateway
sendSketchInfo("4-1 Sensor", "1.0");
// Register all sensors to gw (they will be created as child devices)
present(CHILD_ID_HUM, S_HUM);
present(CHILD_ID_TEMP, S_TEMP);
present(CHILD_ID_MOT, V_TRIPPED); //me
for (int sensor=1, pin=RELAY_1; sensor<=NUMBER_OF_RELAYS; sensor++, pin++) {
// Register all sensors to gw (they will be created as child devices)
present(sensor, S_BINARY);
}
}
void loop()
{
// Read digital motion value
boolean tripped = digitalRead(DIGITAL_INPUT_SENSOR) == HIGH;
// only run loop if time has passed.
unsigned long currentMillis = millis(); // grab current time
// check if "interval" time has passed
if ((unsigned long)(currentMillis - previousMillis) >= interval) {
send(msgMot.set(tripped?"1":"0"));
#ifdef MY_DEBUG
Serial.print("Motion: ");
Serial.println(tripped);
#endif
// Fetch temperatures from DHT sensor
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);
}
send(msgTemp.set(temperature, 1));
#ifdef MY_DEBUG
Serial.print("T: ");
Serial.println(temperature);
#endif
}
// Fetch humidity from DHT sensor
float humidity = dht.getHumidity();
if (isnan(humidity)) {
Serial.println("Failed reading humidity from DHT");
} else if (humidity != lastHum) {
lastHum = humidity;
send(msgHum.set(humidity, 1));
#ifdef MY_DEBUG
Serial.print("H: ");
Serial.println(humidity);
#endif
}
// save the "current" time
previousMillis = millis();
}
// Sleep until interrupt comes in on motion sensor. Send update every two minute.
//sleep(digitalPinToInterrupt(DIGITAL_INPUT_SENSOR), CHANGE, SLEEP_TIME);
}
void receive(const MyMessage &message)
{
// We only expect one type of message from controller. But we better check anyway.
if (message.type==V_STATUS) {
// Change relay state
digitalWrite(message.sensor-1+RELAY_1, message.getBool()?RELAY_ON:RELAY_OFF);
// Store state in eeprom
saveState(message.sensor, message.getBool());
// Write some debug info
Serial.print("Incoming change for sensor:");
Serial.print(message.sensor);
Serial.print(", New status: ");
Serial.println(message.getBool());
}
}
However, when i look in domoticz the relay isnt presented as a child.
Plus, the motion sensor is called "S_LIGHT_LEVEL" and not "S_MOTION" as it does in my other device (that only have temp, hum motion and not a relay in the sketch).
temp/hum sensor and motion sensor works as intended in domoticz.
My first though is that the motion and relay somehow is a bit mixed up by the sketch, but im kinda new to this so im not sure.
Would really appreciate if someone can look at the sketch and see if there is any obvious problem :)
