Configuration

Description

Configuration is done through config.yml The parent folder of the file can be specified with -c PATH or --config PATH. If nothing is specified the file config.yml is searched in the subdirectory HABApp in

  • the current working directory

  • the venv directory

  • the user home

If the config does not yet exist in the folder a blank configuration will be created

Example

directories:
    logging: log    # If the filename for the logfile in logging.yml is not absolute it will be placed in this directory
    rules: rules    # All *.py files in this folder (and subfolders) will be loaded. Load order will be alphabetical by path.
    param: param    # Optional, this is the folder where the parameter files will be created and loaded from
    config: config  # Folder from which configuration files for openHAB will be loaded
    lib: lib        # Custom modules, libraries and files can be placed there.
                    # (!) Attention (!):
                    # Don't create rule instances in files inside the lib folder! It will lead to strange behaviour.

location:           # Specify the location where your HABApp instance is running
  latitude: 0.0     # The value is used to calculate the Sunrise/Sunset etc accordingly
  longitude: 0.0
  elevation: 0.0

openhab:
    ping:
        enabled: true        # If enabled the configured item will show how long it takes to send an update from HABApp
                             # and get the updated value back in milliseconds
        item: 'HABApp_Ping'  # Name of the NumberItem that will show the ping
        interval: 10         # Seconds between two pings

    connection:
        url: http://localhost:8080
        user: ''
        password: ''

    general:
        listen_only: False  # If True  HABApp will not change any value on the openHAB instance.
                            # Useful for testing rules from another machine.
        wait_for_openhab: True   # If True HABApp will wait for items from the openHAB instance
                                 # before loading any rules on startup


mqtt:
    connection:
        client_id: HABApp
        host: ''
        port: 8883
        user: ''
        password: ''
        tls:
          enabled: false   # Enable TLS for the connection
          insecure: false  # Validate server hostname in server certificate
          ca cert: ''      # Path to a CA certificate that will be treated as trusted
                           # (e.g. when using a self signed certificate)

    subscribe:         # Changes to Subscribe get picked up without restarting HABApp
        qos: 0         # Default QoS for subscribing
        topics:
        - '#'               # Subscribe to this topic, qos is default QoS
        - ['my/topic', 1]   # Subscribe to this topic with explicit QoS

    publish:
        qos: 0          # Default QoS when publishing values
        retain: false   # Default retain flag when publishing values

    general:
        listen_only: False # If True  HABApp will not publish any value to the broker.
                           # Useful for testing rules from another machine.

Configuration Reference

All possible configuration options are described here. Not all entries are created by default in the config file and one should take extra care when changing those entries.
