Method for controlling at least one motorised rolling blind of at least one opening of a room of a building, the method comprises the steps of: - obtaining a current mode of a heating control device of the at least one room, the current mode of the heating control device of the at least one room is a heating control mode or a heating control inhibition mode, - obtaining the value of the temperature in the at least one room, - obtaining the value of the solar radiation, - obtaining a value of at least one parameter from the current mode of the heating control device of the at least one room, - deciding on a control of the motorised rolling blind from the value of the at least one parameter obtained, - controlling the motorised rolling blind according to the decision, characterized in that the deciding of the control of the motorised rolling blind is performed by comparing the value of the solar radiation to at least one parameter value obtained from the current mode of the heating control device of the at least one room, the at least one parameter value obtained from the current mode of the heating control device of the at least one room is further dependent on the temperature of the at least one room obtained and the time at which the temperature of the room of the building and the solar radiation are obtained, the at least one parameter value obtained from the current mode of the heating control device is obtained from two straight lines, each of the straight lines having a directing coefficient and an ordinate at the origin, on the abscissa axis the time is represented, on the ordinate axis the solar radiation measured by the sensor is represented, the directing coefficient and the ordinate at the origin being a function of the current mode of the heating control device and of a level of criticality representative of the deviation between the temperature and a first and second threshold, the level of criticality being able to be equal to one, two or three, the directing coefficients being equal to 0 if the value of the level of criticality is equal to 1 or 3 in heating control inhibition mode, the directing coefficients being equal to 0 in heating control mode, the directing coefficients being equal to 10 if the value of the level of criticality is equal to 2 in heating control inhibition mode, the ordinate of the first affine straight line is equal to 2000 if the level of criticality is equal to 1 in heating control inhibition mode, the ordinate of the second affine straight line is equal to 2000 if the level of criticality is equal to 1 in heating control inhibition mode, the ordinate of the first affine straight line is equal to 200 if the level of criticality is equal to 2 in heating control inhibition mode, the ordinate of the second affine straight line is equal to 400 if the level of criticality is equal to 2 in heating control inhibition mode, the ordinate of the first affine straight line is equal to 150 if the level of criticality is equal to 3 in heating control inhibition mode, the ordinate of the second affine straight line is equal to 150 if the level of criticality is equal to 3 in heating control inhibition mode, the ordinate of the first affine straight line is equal to 2000 if the level of criticality is equal to 1 in heating control mode, the ordinate of the second affine straight line is equal to 2000 if the level of criticality is equal to 1 in heating control mode, the ordinate of the first affine straight line is equal to 500 if the level of criticality is equal to 2 in heating control mode, the ordinate of the second affine is equal to 700 if the level of criticality is equal to 2 in heating control mode, the ordinate of the first affine straight line is equal to 400 if the level of criticality is equal to 3 in heating control mode, the ordinate of the second affine straight line is equal to 400 if the level of criticality is equal to 3 in heating control mode. - obtaining a current mode of a heating control device of the at least one room, the current mode of the heating control device of the at least one room is a heating control mode or a heating control inhibition mode, - obtaining the value of the temperature in the at least one room, - obtaining the value of the solar radiation, - obtaining a value of at least one parameter from the current mode of the heating control device of the at least one room, - deciding on a control of the motorised rolling blind from the value of the at least one parameter obtained, - controlling the motorised rolling blind according to the decision,
