Multiscrape, unable to find the correct selector

HI.
After loosing my complete HA setup i am now rebuilding everything.
I managed to get everything up and running again but i am unable to find the correct selector for scraping the website of my own weatherstation.
Attached is the image of the the weatherstations website and the value i want to scrape.
Maybe someone can help me here.
This is my configuration:

- resource: http://192.168.178.63/livedata.html
  scan_interval: 17
  sensor:
    - unique_id: wetterstation_aussentemp
      name: wetterstation aussentemp
      select: "body > table > tbody > tr:nth-child(16) > td:nth-child(2) > input > item(2)"
      value_template: "{{ value }}"
