crates.io page

homie-influx is a service to connect to an MQTT broker, discover devices following the Homie convention, and record their property value changes to an InfluxDB database.

See the main project readme for more details and background.


It is recommended to install the latest release from our Debian repository:

$ curl -L https://homiers.jfrog.io/artifactory/api/security/keypair/public/repositories/homie-rs | sudo apt-key add -
$ echo "deb https://homiers.jfrog.io/artifactory/homie-rs stable main" | sudo tee /etc/apt/sources.list.d/homie-rs.list
$ sudo apt update && sudo apt install homie-influx

Alternatively, you may install with cargo install, but that will require some more setup:

$ cargo install homie-influx


If you have installed the Debian package, the service will be set up with systemd for you already. Otherwise, copy the homie-influx binary to /usr/bin, copy debian-scripts/homie-influx.service to /lib/systemd/system, create a homie-influx user to run as, and create /etc/homie-influx for configuration files.

There should be two config files under /etc/homie-influx:

  • homie-influx.toml contains the main configuration for the service, such as which MQTT broker and InfluxDB server to connect to. See homie-influx.example.toml for an example of the settings that are supported.
  • mappings.toml contains a map of Homie base topics to InfluxDB databases. By default it will look for devices under the standard homie base topic and write to an InfluxDB database called test. You can add multiple base topics to handle multiple users.

After editing these config files you will need to restart the service:

$ sudo systemctl restart homie-influx.service

You may find it helpful to watch the logs to see whether it is managing to connect:

$ sudo journalctl -u homie-influx.service --output=cat --follow


This service publishes up to six measurements: integer, float, boolean, string, enum, color, corresponding to the Homie datatypes. Each message is published as an InfluxDB point with the appropriate name and timestamp, the value as a value field, and device / node / property info included as tags.

In order to support Grafana clients, boolean points also have an additional value_int field, which is an integer, 1 for true or 0 for false.
