Homemade thermostat to control from ha

Hello.
I’m trying to make a homemade thermostat to control from ha. The tactic is as follows: less than 20 nothing works, turns on from 20 to 30 hysteresis 0.5
How can I get hysteresis from the assistant? And apply this in a lambda?
Controlling tp_global u ha via input_number
Check out my code) can it be optimized?

This is not how it works, only manual numbers …

Not WORK if (id(tp_obratka).state < (id(tp_global) - id(tp_gist)))
work  if (id(tp_obratka).state < id(tp_global) - 0.5 )

You don’t have code for all conditions.

if (id(tp_podacha).state > 20 ) {
     if (id(tp_obratka).state < (id(tp_global) - id(tp_gist))) {
       id(tp_nasos).turn_on();
     }
     else if (id(tp_obratka).state > id(tp_global) ) {
           id(tp_nasos).turn_off();
     }
	 //NOTHING HAPPENS WHEN THIS CONDITION IS MET HERE
 }  
else	{
    id(tp_nasos).turn_off();
 }
