Scrape Yaml

Configuration
1

I want to put scrape code directly in the yaml instead of using the visual part of the integration and I can’t get it to work… any ideas? This is the code, if I configure it from the visual with the same data it works but if I put this code in the sensors section, when I restart the system the sensor doesn’t even appear.

  - platform: scrape
    resource: https://www.dinoonline.com.ar/super/producto/aceite-de-girasol-natura-x-15-lt/_/A-2320031-2320031-s
    name: Aceite
    select: "#addToCartx > div:nth-child(5) > div:nth-child(1) > div > div > div.precio-unidad > span"
    scan_interval: 43200 
    value_template: "{{ value | float }}"  
    unit_of_measurement: "ARS"

Look at the YAML example in the documentation: Scrape - Home Assistant

Scrape is not a sensor platform it is its own integration. It goes under it’s own integration in your configuration.yaml file not under sensor:

# configuration.yaml
scrape:
  - resource: https://www.dinoonline.com.ar/super/producto/aceite-de-girasol-natura-x-15-lt/_/A-2320031-2320031-s
    scan_interval: 43200 
    sensor:
      - name: "Globos"
        select: "#addToCartx > div:nth-child(5) > div:nth-child(1) > div > div > div.precio-unidad > span"
        unit_of_measurement: "ARS"

I tried it there and the same thing happens, when I restart it the sensor doesn’t even appear.

Did you format it correctly as I have done above?

Did you restart or reload after doing that?

What entity id are you looking for?

It should be called sensor.aceite_de_prueba

Errors in Settings → System → Logs?

I just checked the log and found this error.

The above exception was the direct cause of the following exception:

I added it there,

value_template: "{{ value.replace('$', '').replace(',', '').strip() | float }}"

and it worked. Honestly, I hadn’t realized to check the logs. Thanks so much!!
