Abstract

Motorized window treatments may each adjust a position of a covering material to allow light into a space in a building. The control information for controlling the motorized window treatments may be stored and/or accessed to understand how the motorized window treatments are operating. The control information may indicate a control state and/or a position of the covering material when an identified daylight intensity is being received at the space. The control information may inform a user of the operation of the motorized window treatments and allow the user to adjust various control parameters by which the motorized window treatments may be controlled. Recommended adjustments may also be provided to the user based on a user-identified problem with the operation of the motorized window treatments. The recommended adjustments to the control parameters may be accepted by the user and may be stored for being accessed and/or edited.

First claim

What is claimed is:

1. A method for controlling a motorized window treatment in a space, the motorized window treatment comprising a covering material and configured to adjust a position of the covering material in response to received messages, the method comprising:
storing in memory, by at least one control circuit, daylight intensities determined from measurements made by at least one sensor over a period of time;
storing in the memory, by the at least one control circuit, motorized window treatment control information reflecting control of the motorized window treatment over the period of time,
wherein the motorized window treatment control information comprises a plurality of control states over the period of time, and a plurality of positions to which the covering material was adjusted over the period of time, wherein each position of the plurality of positions is associated with at least one of the plurality of control states and is further associated with at least one of the daylight intensities;

receiving, by the at least one control circuit from a computing device via a communications network, a request for the motorized window treatment control information and the daylight intensities, wherein the request comprises the period of time associated with the motorized window treatment control information and the daylight intensities;
accessing from the memory, by the at least one control circuit, the motorized window treatment control information and the daylight intensities associated with the period of time;
accessing, by the at least one control circuit, motorized window treatment control parameters for the period of time, wherein the motorized window treatment was controlled according to the motorized window treatment control parameters over the period of time;
displaying, by the at least one control circuit via a graphical user interface on the computing device, the accessed motorized window treatment control information, the accessed daylight intensities, and at least one of the motorized window treatment control parameters;
receiving, by the at least one control circuit from the computing device, an adjustment to at least one motorized window treatment control parameter;
based at least in part on the adjustment to the at least one motorized window treatment control parameter, determining, by the at least one control circuit, a position of the covering material for the motorized window treatment; and
communicating, by the at least one control circuit to the motorized window treatment via a communications network, a message that includes the determined position, wherein the motorized window treatment adjusts the covering material to the determined position in response to the message.

2. The method of claim 1 , wherein the plurality of control states includes an automated control state and at least one override state for overriding the automated control state.

3. The method of claim 2 , wherein the at least one override state includes at least one of a bright override state, a manual override state, a hold visor override state, or a dark override state.

4. The method of claim 3 , wherein displaying further comprises displaying the plurality of positions of the covering material, the plurality of control states, and the accessed daylight intensities in a graph that represents the positions of the covering material, the plurality of control states, and the accessed daylight intensities over the period of time.

5. The method of claim 4 , wherein the graph further comprises an indication at each adjustment to the position of the covering material, and wherein each indication is selectable to provide a time of the respective adjustment.

6. The method of claim 1 , wherein the motorized window treatment control parameters include at least one of a visor position, a hold visor override threshold, a bright override threshold, a bright override position, a bright override time period, a bright override hysteresis, a dark override threshold, a dark override hysteresis, a dark override position, a dark override delay time period, a morning ramping period for the dark override threshold, or an evening ramping period for the dark override threshold.

7. The method of claim 1 , wherein the adjusted at least one motorized window treatment control parameter is associated with a bright override state and comprises a bright override threshold, or is associated with a dark override state and comprises a dark override threshold.

8. The method of claim 7 , wherein the dark override state comprises a morning ramping period and an evening ramping period.

9. The method of claim 1 , further comprising:
determining predicted motorized window treatment control information based on the received adjustment to the at least one motorized window treatment control parameter; and
displaying the predicted motorized window treatment control information via a graphical user interface on the computing device.

10. A load control system for controlling an amount of daylight in a space, the load control system comprising:
a motorized window treatment comprising a covering material and configured to adjust the covering material in response to received messages to control the amount of daylight in the space; and
at least one control circuit configured to:
store in memory daylight intensities determined from measurements made by at least one sensor over a period of time;
store in the memory motorized window treatment control information reflecting control of the motorized window treatment over the period of time,
wherein the motorized window treatment control information comprises a plurality of control states over the period of time, and a plurality of positions to which the covering material was adjusted over the period of time, wherein each position of the plurality of positions is associated with at least one of the plurality of control states and is further associated with at least one of the daylight intensities;

receive, from a computing device via a communications network, a request for the motorized window treatment control information and the daylight intensities, wherein the request comprises the period of time associated with the motorized window treatment control information and the daylight intensities;
access from the memory the motorized window treatment control information and the daylight intensities associated with the period of time;
access motorized window treatment control parameters for the period of time, wherein the motorized window treatment was controlled according to the motorized window treatment control parameters over the period of time;
display, via a graphical user interface on the computing device, the accessed motorized window treatment control information, the accessed daylight intensities, and at least one of the motorized window treatment control parameters;
receive, from the computing device, an adjustment to at least one motorized window treatment control parameter;
based at least in part on the adjustment to the at least one motorized window treatment control parameter, determine a position of the covering material for the motorized window treatment; and
communicate, to the motorized window treatment via a communications network, a message that includes the determined position, wherein the motorized window treatment is configured to adjust the covering material to the determined position in response to the message.

11. The load control system of claim 10 , wherein the at least one control circuit is further configured to:
determine predicted motorized window treatment control information based on the received adjustment to the at least one motorized window treatment cont
