Couple of questions

  • Is the HTTP binding installed?
  • Is the REGEX transformation installed?

Try that:

Number HTTPstring "HTTP [%.2f °C]" { http="<[http://192.168.2.20/openhab.html:1000:REGEX((.*?))" }

I tried it and after some tries i found that if i remove the HTTP:// and replace the HTTP from the begin to HTTP1 with lowercase i dont get any error but still the value in the sitemap does not update!

Number HTTPstring "HTTP [%.2f °C]" { **http**="<[http://192.168.2.20/openhab.html:1000:REGEX((.*?))" }

Without error

Number HTTPstring "HTTP [%.2f °C]" { http1="<[192.168.2.20/openhab.html:1000:REGEX((.*?))" }

Duh!!
We both are dummies…
You are missing a ] at the end of your binding string:

Number HTTPstring "HTTP [%.2f °C]" { http="<[http://192.168.2.20/openhab.html:1000:REGEX((.*?))]" }
