I am trying to figure out how to get the scrape component to pull values from a table for a weather station. I am able to get what I want using https://try.jsoup.org/ but I am getting “Unknown” from HA’s Scrape component. The site in question is:
https://mesowest.utah.edu/cgi-bin/droman/meso_table_roadwx.cgi?stn=UT30&unit=0&time=&hours=24&hour1=00&day1=00&month1=&year1=&radius=25&past=0&order=0
and the query I constructed is:
body > table > tbody > tr:nth-child(6) > td:nth-child(2) > font > b
to pull windspeed, which works using the jsoup tool.
No matter what I try I either kill the sensor or get Unknown as a result from HA.
Is there a step I am missing? I am currently using the GUI.
There’s no tbody element in that HTML. Rather than using the DevTools selector, just look at the HTML (from View Source, not from DevTools) and work it out.
select: "table > tr:nth-child(6) > td:nth-child(2) > font > b"
value_template: "{{ value|select('in', '.0123456789')|join }}"
unit_of_measurement: "mph"
Thank you, That worked! I have a question on the value template though, Is there a resource on the options available and how to construct it? I was trying to use the docs, but it did not feel like it was giving me enough to understand what was going on and I ended up using other people’s (usually not working) examples to try to figure out how to build mine.
Also, is there a way to set how often this scrapes? The source is only updated every 10 min and I don’t want to DOS their site or be annoying by grabbing too often.
