Hello all,
Good news for bht-6000 tuta/Beca thermostat.
With last update of home assistant 0.118.1 is possible to configure temperature type (centigrade or farenheit) and most important the divided factor for correct the problem like doubled temperature or 10x. Also is possible to set the polling time of update states. So finally is not necessary anymore to edit any line of climate.py.
