No model has yet been created, but this is a first step towards that. I'll do a follow-up\nlater at some point where I also include the load averages and likely some linear regression to build such a model.\n\nI have done a [blog post](https://blog.cfelde.com/2023/12/raspberry-pi-vs-room-temp/) if you're keen, but here's what\nthe chart looks like:\n\n![Temperature chart](chart.png)\n\n## How to run\n\nI've included the temperature logs in the `data` folder.\n\nYou can build and run using these files like so:\n\n``` sh\n./gradlew clean build\njava -jar build/libs/raspberry-pi-temperature-1.0-all.jar data/temperature.log data/outside_temp.log\n```\n\nWhen running you can access the chart and temperature table in your browser from the URLs printed to the console.\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcfelde%2Fraspberry-pi-temperature","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcfelde%2Fraspberry-pi-temperature","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcfelde%2Fraspberry-pi-temperature/lists"}
