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:
sh
$ curl -L https://bintray.com/user/downloadSubjectPublicKey?username=homie-rs | sudo apt-key add -
$ echo "deb https://dl.bintray.com/homie-rs/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:
sh
$ 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:
.env contains the main configuration for the service, such as which MQTT broker and InfluxDB server to connect to. See .env.example for an example of the settings that are supported.mappings.conf 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:
sh
$ sudo systemctl restart homie-influx.service
You may find it helpful to watch the logs to see whether it is managing to connect:
sh
$ sudo journalctl -u homie-influx.service --output=cat --follow
