Reading data from PWS Bresser 5-in-1 (7002581) via Port 5000

Hi,

I would like to integrate our Bresser 5-in-1 weather station (7002581) into HA.
The usual suggestions are to use the integrations for Weathercloud or Wunderground or read the data via 868 MHz.

I tried a port scan and saw that port 5000 is open. Reading data from it yields

0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz
0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz
0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz
0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\]^_`abcdefghijklmnopqrstuvwxyz

forever.
I think if you use a different endpoint or supply parameters that you could get the data out if it and parse it. But I could not find anything online or here in the forum.
Do you have and idea on how this could be done or further investigated?

Bye,
Markus
