Sensors

Subscribe to all the messages with mosquitto or open your MQTT client software:

sudo mosquitto_sub -t +/# -v

ADC

The value is between 0 and 1024 and is tranmitted via Mqtt when it changes. home/OpenMQTTGateway/DHTtoMQTT {"value":543}

DHT

You will receive every TimeBetweenReadingDHT (set into config_DHT.h) the DHT measurement (30s per default).

home/OpenMQTTGateway/DHTtoMQTT {"temp":21,"hum":51}

If you want to don't resend value when it is the same you can set dht_always = false in config_DHT.h

HTU21

You will receive the HTU21 sensor readings every TimeBetweenReadinghtu21 (set into config_HTU21.h) (30s by default).

home/OpenMQTTGateway/CLIMAtoMQTT/htu {"tempc":25.34064,"tempf":77.61314,"hum":56.53052}

If you don't want to resend values that haven't changed you can set htu21_always = false in config_HTU21.h

AHTx0 (AHT10 and AHT20)

You will receive the AHT sensor readings every TimeBetweenReadingAHTx0 (set into config_AHTx0.h) (30s by default).

home/OpenMQTTGateway/CLIMAtoMQTT/aht { "tempc": 27.48108, "tempf": 81.46594, "hum": 48.90614 }

If you don't want to resend values that haven't changed you can set AHTx0_always = false in config_AHTx0.h

DS18x20

You will receive the DS18x20 sensor readings every DS1820_INTERVAL_SEC (set into config_DS1820.h) (60s by default). Each sensor will be published under the following topic using each sensors' address.

home/OpenMQTTGateway/CLIMAtoMQTT/ds1820/0x0000000000000000 {"temp":27.8,"unit":"C","type":"DS18B20","res":"12bit\n","addr":"0x28616411907650bc"}

The units for temperature readings are sent in Celcius by default can be changed to ferenheight by setting DS1820_FAHRENHEIT = true in in config_DS1820.h

If you don't want to resend values that haven't changed you can set DS1820_ALWAYS = false in config_DS1820.h

HCSR501

A boolean value of the PIR sensors state is sent when a state change occurs. The length of time that the PIR stays in a triggered state depends on the PIR hardware and is not changed by OpenMQTTGateway.

home/OpenMQTTGateway/HCSR501toMQTT {"hcsr501":"false"}

You can have another PIN mirror the value of the PIR sensor output by adding the following to config_HCSR501.h This can be useful if you would like to connect an LED to turn on when motion is detected.

#define HCSR501_LED_NOTIFY_GPIO 4
