The `scrape` sensor platform is scraping information from websites. The sensor loads an HTML page and gives you the option to search and split out a value. As this is not a full-blown web scraper like [scrapy](https://scrapy.org/), it will most likely only work with simple web pages and it can be time-consuming to get the right section.
Check Beautifulsoup's [CSS selectors](https://www.crummy.com/software/BeautifulSoup/bs4/doc/#css-selectors) for details on how to write a **Select**.
If you are not using Home Assistant Container or Home Assistant Operating System, this integration requires `libxml2` to be installed. On Debian based installs, run:
```bash
sudo apt install libxml2
```
{% include integrations/config_flow.md %}
To enable this sensor, add the following lines to your `configuration.yaml` file:
