Create an heating only thermostat

Hello,

I would like to make a thermostat to control a glycol heating (underfloor heating) I try with esphome to use “bang bang thermostat” but when I import it into home assistant I always get a double thermostat (min and max) but in my case its only heating. I would like the thermostat to work alone if the home assistant had just stopped working.

Otherwise we have a way to make a generic thermostat in home but the temperature setpoint can be modified in home but the esp keeps in memory the last setpoint received

I did something temporary with overheating and freeze security but is not perfect

Thanks all for your help
