Also für mich sieht der Sketch so aus, als wenn nur Debug Messages verarbeitet werden.
Die Nachrichten ans Gateway sollten eigentlich so aussehen.
Z.B Luftfeuchtigkeit.
send(msgHum.set(humidity, 1));Irgendwie fehlt mir in dem Loop des Sketchs genau dieser Teil.
Ich würde auch grundsätzlich bei sowas mit dem einfachsten Gatewaysketch aus den Beispielen anfangen, ohne OTA und Verschlüsselung.
Sowas wie hier das sollte erstmal gehen, richtige Libs vorrausgesetzt:
// Enable debug prints to serial monitor
#define MY_DEBUG
// Use a bit lower baudrate for serial prints on ESP8266 than default in MyConfig.h
#define MY_BAUD_RATE 9600
// Enables and select radio type (if attached)
#define MY_RADIO_NRF24
#define MY_RF_24_PA_LEVEL RF24_PA_MIN
#define MY_GATEWAY_ESP8266
#define MY_ESP8266_SSID "SSID"
#define MY_ESP8266_PASSWORD "Passwort"
// The port to keep open on node server mode
#define MY_PORT 5003
// How many clients should be able to connect to this gateway (default 1)
#define MY_GATEWAY_MAX_CLIENTS 2
#if defined(MY_USE_UDP)
#include <WiFiUdp.h>
#endif
#include <SPI.h>
#include <ESP8266WiFi.h>
#include <MySensors.h>
#include <DHT.h>
#define DHT_DATA_PIN 4
// Set this offset if the sensor has a permanent small offset to the real temperatures
#define SENSOR_TEMP_OFFSET 0
// Sleep time between sensor updates (in milliseconds)
// Must be >1000ms for DHT22 and >2000ms for DHT11
static const uint64_t UPDATE_INTERVAL = 2000;
// Force sending an update of the temperature after n sensor reads, so a controller showing the
// timestamp of the last update doesn't show something like 3 hours in the unlikely case, that
// the value didn't change since;
// i.e. the sensor would force sending an update every UPDATE_INTERVAL*FORCE_UPDATE_N_READS [ms]
static const uint8_t FORCE_UPDATE_N_READS = 10;
#define CHILD_ID_HUM 0
#define CHILD_ID_TEMP 1
float lastTemp;
float lastHum;
uint8_t nNoUpdatesTemp;
uint8_t nNoUpdatesHum;
bool metric = true;
MyMessage msgHum(CHILD_ID_HUM, V_HUM);
MyMessage msgTemp(CHILD_ID_TEMP, V_TEMP);
DHT dht;
void presentation()
{
// Send the sketch version information to the gateway
sendSketchInfo("TemperatureAndHumidity", "1.1");
// Register all sensors to gw (they will be created as child devices)
present(CHILD_ID_HUM, S_HUM);
present(CHILD_ID_TEMP, S_TEMP);
metric = getControllerConfig().isMetric;
}
void setup()
{
dht.setup(DHT_DATA_PIN); // set data pin of DHT sensor
if (UPDATE_INTERVAL <= dht.getMinimumSamplingPeriod()) {
Serial.println("Warning: UPDATE_INTERVAL is smaller than supported by the sensor!");
}
// Sleep for the time of the minimum sampling period to give the sensor time to power up
// (otherwise, timeout errors might occure for the first reading)
sleep(dht.getMinimumSamplingPeriod());
}
void loop()
{
// Force reading sensor, so it works also after sleep()
dht.readSensor(true);
// Get temperature from DHT library
float temperature = dht.getTemperature();
if (isnan(temperature)) {
Serial.println("Failed reading temperature from DHT!");
} else if (temperature != lastTemp || nNoUpdatesTemp == FORCE_UPDATE_N_READS) {
// Only send temperature if it changed since the last measurement or if we didn't send an update for n times
lastTemp = temperature;
if (!metric) {
temperature = dht.toFahrenheit(temperature);
}
// Reset no updates counter
nNoUpdatesTemp = 0;
temperature += SENSOR_TEMP_OFFSET;
send(msgTemp.set(temperature, 1));
#ifdef MY_DEBUG
Serial.print("T: ");
Serial.println(temperature);
#endif
} else {
// Increase no update counter if the temperature stayed the same
nNoUpdatesTemp++;
}
// Get humidity from DHT library
float humidity = dht.getHumidity();
if (isnan(humidity)) {
Serial.println("Failed reading humidity from DHT");
} else if (humidity != lastHum || nNoUpdatesHum == FORCE_UPDATE_N_READS) {
// Only send humidity if it changed since the last measurement or if we didn't send an update for n times
lastHum = humidity;
// Reset no updates counter
nNoUpdatesHum = 0;
send(msgHum.set(humidity, 1));
#ifdef MY_DEBUG
Serial.print("H: ");
Serial.println(humidity);
#endif
} else {
// Increase no update counter if the humidity stayed the same
nNoUpdatesHum++;
}
// Sleep for a while to save energy
sleep(UPDATE_INTERVAL);
}
Da es ja ein Gateway ist würde ich das noch mit dem Sleep ím Loop anders machen.
