prometheus_dyson
Prometheus client for DysonLink fans (e.g; Pure Hot+Cool and Pure Cool).
This code supports Dyson Pure Cool and Pure Hot+Cool fans. This supports both the V1 model (reports VOC and Dust) and the V2 models (those that report PM2.5, PM10, NOx, and VOC). Other Dyson fans may work out of the box or with minor modifications.
Build
% bazel build :main
If you'd like a Debian package:
% bazel build :main-deb
Without Bazel
Tip: a Python virtual environment is a very useful tool for keeping dependencies local to the project (rather than system-wide or in your home directory). This is optional and not required.
You'll need these dependencies:
% pip install libpurecool
% pip install prometheus_client

Usage
Configuration
This script reads config.ini
(or another file, specified with --config
)
for your DysonLink login credentials.
Args
% ./prometheus_dyson.py --help
usage: ./prometheus_dyson.py [-h] [--port PORT] [--config CONFIG] [--log_level LOG_LEVEL] [--include_inactive_devices]
optional arguments:
-h, --help show this help message and exit
--port PORT HTTP server port
--config CONFIG Configuration file (INI file)
--log_level LOG_LEVEL
Logging level (DEBUG, INFO, WARNING, ERROR)
--include_inactive_devices
Monitor devices marked as inactive by Dyson (default is only active)
Scrape Frequency
Metrics are updated at approximately 30 second intervals by libpurecool
.
Fan state changes (e.g; FAN -> HEAT) are published ~immediately on change.
Other Notes
libpurecool
by default uses a flavour of mDNS to automatically discover
the Dyson fan. If automatic discovery isn't available on your network, it is possible
to specify IP addresses mapped to device serial numbers in config.ini - see
config-sample.ini
for usage.
Dashboard
I've provided a sample Grafana dashboard in grafana.json
