I am trying to scrape this website for my son’s BMI. This gives a webpage with BMI, BMI classification (health or overweight) and the percentile. all of which i can pull thanks to scrape component.
However, the parameters are everchanging and yet important. Is there any way to template this URL which is taken by the scrape sensor as “resource”. i track my sons weight and height as input_numbers so i do have all the inputs.

is the URL changing?
All the site does is compute some calculations and displays them. A scrape sensor would be overkill if you could simply do the computing yourself in HA with the right formula? BMI = (weight in kg ) / (height in m x height in m)
I had a quick look and not found a formula to calculate the percentile, but there is probably one somewhere out there…

Lolouk, hello again . Yes i found another challenge with scrape sensor apart from being an overkill. If the website uses javascript to compute what you want it will not work out because scrape sensor is not executing javascript.
I found the JS code that this website is using to compute percentile but but will take a while to make sense of how it is calculating percentile.
Nonetheless, i will go with your suggestion and just do compute it locally.
