Breaking change

Proposed change

Fixes a bug that made the integration break when setting fan setpoints.

The Flexit App works like this: if the Home extract/supply setpoint is 74, then the Away extract/supply setpoint must be 74 or lower i.e., max values for the Away extract/supply setpoints is the setpoints for Home extract/supply.

High setpoints can't be set lower than Home setpoints.

Also for setpoints not depending on other setpoints, the lowest value seems to be 30 (not 0, see screenshots and table below).

Mode	Setpoint	Min	Max
HOME	Supply	AWAY Supply setpoint	100
HOME	Extract	AWAY Extract setpoint	100
AWAY	Supply	30	HOME Supply setpoint
AWAY	Extract	30	HOME Extract setpoint
HIGH	Supply	HOME Supply setpoint	100
HIGH	Extract	HOME Extract setpoint	100
COOKER_HOOD	Supply	30	100
COOKER_HOOD	Extract	30	100
FIREPLACE	Supply	30	100
FIREPLACE	Extract	30	100
