Scrape

The scrape sensor integrationIntegrations connect and integrate Home Assistant with your devices, services, and more. [Learn more] scrapes information from websites. The sensor loads an HTML page, and allows you to search and extract specific values. As this is not a fully featured web scraper like scrapy, it will work with simple web pages and it can be time-consuming to get the right section.

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:

sudo apt install libxml2

Both UI and YAML setup is supported while YAML provides additional configuration possibilities.

Using templates

For incoming data, a value template translates incoming JSON or raw data to a valid payload. Incoming payloads are rendered with possible JSON values, so when rendering, the value_json can be used to access the attributes in a JSON based payload, otherwise the value variable can be used for non-json based data.

Additional, the this can be used as variables in the template. The this attribute refers to the current entity state of the entity. Further information about this variable can be found in the template documentation

{ "state": "ON", "temperature": 21.902 }
