zones={
-- start and stop indicates the comport period (hour of the day) when temperature must be equal to the setpoint
-- offset is the max tolerated difference from set temperature outside the comfort period
-- weight is used to set the importance of temperature in each rooms. 1=very important, 0.5 means that temperature can be a bit different from the set point, 0=ignore temperature in this room. If weight is less than 1, it's tolerated a greater offset in case there is not enough energy from renewable (photovoltaic)

-- Zone name is "Cucina" (kitchen)
-- Temperature sensor is "Temp_Cucina"
-- RH sensor is "RH_Cucina"
-- No electrovalve for this room (always enabled)
-- During the winter, keep the setpoint from 5:00 to 22:00 (comfort period), and keep setpoint-0.2 (offset) outside the comfort period. This zone is really important, so weight=1
-- During the summer, keep setpoin from 7:00 to 23:00, then temperature can raise to setpoint+0.2. Weight is 1 (important zone)
