i want it to be input of payload_template: as shown on the left.
Thank you.
You are going about things a very odd and convoluted way.
Create a mqtt sensor is where you should start.

thank you for the advice I did as you suggested.
sensor display {34AB9527089500000005010100 32 8F}
I want the sensor to show only the number 32 that I highlighted in the picture on the left, what should I do?
I am not brilliant at templating, but you need to split the string and choose the second result.
Add a value_template option to your MQTT Sensor definition containing a template that extracts the desired characters from the received string (fifth character from the end to the third character from the end).
mqtt:
sensor:
- name: "BBB"
state_topic: "response/app/34AB95270895/#"
value_template: "{{ value[-5:-3] }}"
unit_of_measurement: "C"
The template employs python slicing.
