Louvered blinds, roll blinds.

Available device functions

The device can have all the functions listed below or some of them. E.g. if the device cannot manage light transmission at some percentage, there is no need in including the light_transmission_percentage function in its model description.

The device has mandatory functions: online, open_state. In addition, the opening method must be described: open_set, open_percentage, or both.

When using open_set and open_percentage simultaneously, the following rule must be complied with:

• If open_percentage is not equal to zero, then open_set must take the open value. And, vice versa, if the value of open_set is open, open_percentage must be more than zero.
• If open_percentage is equal to zero, then open_set must take the close value. And, vice versa, if the value of open_set is close, open_percentage must be equal to zero.

When changing the values of the open_left_state, open_left_percentage, open_right_state, open_right_percentage functions, those of the open_state, open_percentage functions must change respectively.

Louvered blinds or roller blinds model description example

The model shall be described in accordance with the model structure. The example describes louvered blinds equipped with all functions except for managing the light transmission at some percentage.

Besides, allowed values for the open_rate function (device opening speed) of the model are changed: it can be opened at only three speeds; the medium speed is not supported and therefore deleted.
