Command line sensor issue - ito leva espresso hardware

Configuration
1

I have an issue with a command line sensor wich should give the temperature of my espresso machine, wich was kindly shared by stangster in the kaffee-netz.de forum.

addendum:
Please note that I have been informed that the code was partially created using ChatGPT.
The quality and functionality are therefore questionable.

command_line:
 - sensor:
     name: "ito temperature"
     command: >-
       printf 'MC@\r\n' |
       nc -w 3 192.168.2.67 23 |
       tr -d '\r' | head -n 1 | sed -E 's/^<|>$//g' |
       awk '
         {
           t=""; he="";
           if (match($0, /:[[:space:]]*([0-9]+(\.[0-9]+)?)([[:space:]]*°)?/, m)) t=m[1];
           if (match($0, /([0-9]+(\.[0-9]+)?)%/, h)) he=h[1];
         }
         END {
           if (t=="" || he=="") exit 1;  # keine Ausgabe -> unavailable
           printf("{\"temp_c\":%s,\"heater_pct\":%s}\n", t, he);
         }'
     scan_interval: 10
     command_timeout: 5
     unit_of_measurement: "°C"
     value_template: "{{ value_json.temp_c | float }}"
     availability_template: "{{ value != '' }}"
     json_attributes:
       - heater_pct

I get this error in my log:

Invalid config for 'command_line' at configuration/command_line.yaml, line 27: 'availability_template' is an invalid option for 'command_line'

Can someone spot what’s wrong?
Assistance would be greatly appreciated.

Exactly what the error message says: you can’t use availability_template in a command line sensor. The option is called availability:
