The sensor loads a 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. To enable this sensor, add the following lines to your `configuration.yaml` file: ```yaml # Example configuration.yaml entry sensor: - platform: scrape resource: https://www.home-assistant.io select: ".current-version h1" ``` {% configuration %} resource: description: The URL to the website that contains the value. required: true type: string select: description: "Defines the HTML tag to search for. Check Beautifulsoup's [CSS selectors](https://www.crummy.com/software/BeautifulSoup/bs4/doc/#css-selectors) for details." required: true type: string attribute: description: Get value of an attribute on the selected tag. required: false type: string name: description: Name of the sensor. required: false default: Web scrape type: string unit_of_measurement: description: Defines the units of measurement of the sensor, if any. required: false type: string authentication: description: Type of the HTTP authentication. Either `basic` or `digest`. required: false type: string username: description: The username for accessing the website. required: false type: string password: description: The password for accessing the website. required: false type: string headers: description: Headers to use for the web request. required: false type: string {% endconfiguration %} ## {% linkable_title Examples %} In this section you find some real-life examples of how to use this sensor. There is also a [Jupyter notebook](https://nbviewer.jupyter.org/github/home-assistant/home-assistant-notebooks/blob/master/other/web-scraping.ipynb) available for this example to give you a bit more insight. ### {% linkable_title Home Assistant %} The current release Home Assistant is published on [https://www.home-assistant.io/](/) {% raw %} ```yaml sensor: # Example configuration.yaml entry - platform: scrape resource: https://www.home-assistant.io name: Release select: ".current-version h1" value_template: '{{ value.split(":")[1] }}' ``` {% endraw %} ### {% linkable_title Available implementations %} Get the counter for all our implementations from the [Component overview](/components/) page. {% raw %} ```yaml # Example configuration.yaml entry sensor: - platform: scrape resource: https://www.home-assistant.io/components/ name: Home Assistant impl. select: 'a[href="#all"]' value_template: '{{ value.split("(")[1].split(")")[0] }}' ``` {% endraw %} ### {% linkable_title Get a value out of a tag %} The German [Federal Office for Radiation protection (Bundesamt für Strahlenschutz)](http://www.bfs.de/) is publishing various details about optical radiation including an UV index. This example is getting the index for a region in Germany. ```yaml # Example configuration.yaml entry sensor: - platform: scrape resource: http://www.bfs.de/DE/themen/opt/uv/uv-index/prognose/prognose_node.html name: Coast Ostsee select: 'p:nth-of-type(19)' unit_of_measurement: 'UV Index' ``` ### {% linkable_title IFTTT status %} If you make heavy use of the [IFTTT](/components/ifttt/) web service for your automations and are curious about the [status of IFTTT](http://status.ifttt.com/) then you can display the current state of IFTTT in your frontend. ```yaml # Example configuration.yaml entry sensor: - platform: scrape resource: http://status.ifttt.com/ name: IFTTT status select: '.component-status' ``` ### {% linkable_title Get the latest podcast episode file URL %} If you want to get the file URL for the latest episode of your [favorite podcast](https://hasspodcast.io/), so you can pass it on to a compatible media player. ```yaml # Example configuration.yaml entry sensor: - platform: scrape resource: https://hasspodcast.io/feed/podcast name: Home Assistant Podcast select: 'enclosure:nth-of-type(1)' attribute: url ``` ### {% linkable_title Energy price %} This example tries to retrieve the price for electricity. {% raw %} ```yaml # Example configuration.yaml entry sensor: - platform: scrape resource: https://elen.nu/timpriser-pa-el-for-elomrade-se3-stockholm/ name: Electricity price select: ".elspot-content" value_template: '{{ ((value.split(" ")[0]) | replace (",", ".")) }}' unit_of_measurement: "öre/kWh" ``` {% endraw %} ### {% linkable_title BOM Weather %} The Australian Bureau of Meterology website returns an error if the User Agent header is not sent. {% raw %} ```yaml # Example configuration.yaml entry sensor: - platform: scrape resource: http://www.bom.gov.au/vic/forecasts/melbourne.shtml name: Melbourne Forecast Summary select: ".main .forecast p" value_template: '{{ value | truncate(255) }}' # Request every hour scan_interval: 3600 headers: User-Agent: Mozilla/5.0 ``` {% endraw %}
