Installation

In the very near future, dooblr will be able to be installed via pypi/pip. Until then, or if you want the latest, bleeding-edge version, you can install it by cloning or downloading the repo and running pip install inside the root directory:

pip install ./

You should then be able to run dooblr:

dooblr

Docker

dooblr has also been conveniently Dockerized!

You will want to mount or copy your configs into the container at the `/root/.dooblr` directory. An example of how Makers Local 256 uses dooblr can be found in the [makerslocal/dooblr-prod](https://github.com/makerslocal/dooblr-prod) repo.

Example:

docker run -v $(pwd)/config:/root/.dooblr makerslocal/dooblr:latest

Configuration

dooblr is configured using YAML files, and these files are stored in the user’s home directory. On Linux-based systems they’ll need to be in a directory like:

/home/<username>/.dooblr/

On Windows they’re loaded from somewhere like:

C:\Users\<username>\.dooblr\

After the first run of dooblr, this directory will be created, and some default configuration files will be there. dooblr requires a main dooblr.yml that defines MQTT and InfluxDB connections, and one or more measurement configs.

A default-settings dooblr.yml config file will look like:

# dooblr.yaml
global:
    config-dir: /home/<username>/.dooblr/measurements  # Directory that contains dooblr's measurement configs

mqtt:
    host: localhost  # Host, domain name, or IP address of the MQTT broker
    port: 1883       # Port number of the MQTT broker

influxdb:
    host: localhost   # Host, domain name, or IP address of the InfluxDB instance
    port: 8086        # Port number of the InfluxDB instance
    username: root    # Username for the InfluxDB instance
    password: root    # Password for the InfluxDB instance
    database: dooblr  # Database to use in InfluxDB (will be created if it doesn't exist already)

By default, dooblr looks for *.yml measurement configs in the .dooblr/measurements/ directory. Measurement configs are used to tell dooblr which topics and pieces of data need to be pulled from MQTT and pushed to InfluxDB. dooblr expects the MQTT message to contain either a single value or simple JSON data in its payload.

# humidity.yml
humidity:
    parser: single-value
    value_type: float     # Valid value_types are integer, float, boolean, and string
    field_name: humidity  # If no field_name is provided, the default is 'value'
    topics:
    - home/garage/humidity

{"temperature": 40.1, "units":"F", "humidity": 0.12, "label": "blue"}

# temperature.yml
temperature:
    topics:
    - home/kitchen/fridge/temperature
    - home/kitchen/freezer/temperature
    - home/kitchen/+/temperature  # Standard MQTT wildcards also apply here
    fields:
    - temperature
    - humidity
    tags:
    - units
    optional_tags:
    - label  # Maybe not every message on these topics have a "label" property!
