SOLVED - Mobile Alerts and openHAB 3 - http binding + regex


EDIT: Solved - I found my solution in another topic here at

thank you again.

I am relatively new to home automation. I installed openhab 3 as virtual machine a few days ago. I have also a sensor to measure temperature. The temperature can be accessed via web(http).

What I have done so far:

  • http binding installed
  • regex transformation installed
  • thing created (http-binding)
  • channel created with profile regex and added my regex transformation into the regular expression field

But my result is always “undef” or “null” but if I check the html source at regex101 with my regex then I get my result.

Any hints what I am doing wrong?
Thank you in Advance
Best Regards Thomas
