There is still some life. Digging in previous post I found the following procedure, although I still not succeeded pending on finding my PWS port number ---- sudo apt-get update&&sudo apt-get install git cd /home/pi && git clone git://github.com/Doudy/interceptWH2600.git sudo chmod 755 /home/pi/i ...

Now it is working OK . Thank you.
The only problem comes from the local cache.

Currently i am not able to connect my systems neither using https://my.domoticz.com/ nor http://my.domoticz.com/ . Fortunately I still can connect using Dataplicity service and Wormhole.

I have used this script with success. Thank you.

The problem of not obtaining minus sign and decimals is solved by changing:

temperature=tonumber(string.match(line, "%-?%d+.?%d*"))

i.e. the format of the string.

Good luck
