MQTT integration

This program is able to automatically publish its measurements to a MQTT broker/server.
This is done on a fixed interval.
This project does not currently support encrypted MQTT, but it does support MQTT authentication.

Setup

These setup instructions require an already setup MQTT broker/server(for example mosquitto).

  1. Make sure ENABLE_MQTT_PUBLISH is set to 1 in config.h.
  2. Write your MQTT username to mqttuser.txt and your MQTT password to mqttpass.txt.
  3. Set MQTT_BROKER_ADDR in config.h to the address of your MQTT broker/server.
    Also set MQTT_BROKER_PORT to the port your MQTT broker/server if you are using a non standard port.(The default port is 1883)
  4. Set MQTT_PUBLISH_ANONYMOUS in config.h to 1 if you wish to disable MQTT authentication.
  5. Set MQTT_TOPIC_NAMESPACE in config.h if you wish to use something other then your ESP hostname as the first part of the MQTT topic.
  6. If you want to change how often the measurements are published change MQTT_PUBLISH_INTERVAL in config.h.(default interval is 15 seconds)
  7. Build this project and flash it to your ESP.
