vicare-exporter is small library / tool to export the features of your viessmann appliances as prometheus metrics. You're free to use this as you like, e.g. in you own Grafana instance.
The project largely relies on https://github.com/openviess/PyViCare for the communication with the Viessmann API.
Check it's docs for more information.
To run the exporter, you'll at minimum need credentials for the API configured e.g. in a .env file:
VICARE_USERNAME=<your-email/username>
VICARE_PASSWORD=<password>
VICARE_CLIENT_ID=<client id>
# optional - defaults to 9100
VICARE_METRICS_PORT=9111
# optional - defaults to 120 (seconds)
# choose a larger value if you run into rate limit issues
VICARE_POLL_INTERVAL=120
# by default the gateway is ignored - to avoid rate limit issues
VICARE_IGNORE_DEVICE_IDS=gateway
# get more/less logs (default: INFO)
VICARE_LOGLEVEL=INFO
