How it works

We're using IKEA Alpstuga sensors for CO2 detection, connected to Home Assistant for data collection. Every 5 minutes, we capture a screenshot of the Home Assistant dashboard to populate the image above. We also get the last hour of sensor readings from Home Assistant for each sensor, and reduce the time resolution. These are all saved as static HTML pages, uploaded to Tigris object storage.

The code for the HTML generation lives on Github. Feel free to log issues or make PRs if you see anything that needs tweaking. Reach out to Ben if you have any other questions!
