Multiple interacting systems at a site
View Patent ↗Disclosed are platforms for communicating among one or more otherwise independent systems involved in controlling functions of buildings or other sites having switchable optical devices deployed therein. Such independent systems include a window control system and one or more other independent systems such as systems that control residential home products (e.g., thermostats, smoke alarms, etc.), HVAC systems, security systems, lighting control systems, and the like. Together the systems control and/or monitor multiple features and/or products, including switchable windows and other infrastructure of a site, which may be a commercial, residential, or public site.
1. A window control system, comprising at least one controller configured (i) to control an optical state of one or more optically switchable windows in a building and (ii) to interact directly, by way of an application programming interface (API), with at least one other system of the building selected from at least one member of the group consisting of a lighting system, a heating, ventilation and air conditioning (HVAC) system, a security system, and a home appliance control system and not to interact with a building management system of the building.
2. The window control system of claim 1 , wherein the window control system comprises a window controller configured to control transitions of at least one optically switchable window.
3. The window control system of claim 2 , wherein the window control system comprises a plurality of electrochromic windows in electrical communication with one or more window controllers configured to communicate over a network.
4. The window control system of claim 1 , wherein the at least one other system is the home appliance control system.
5. The window control system of claim 1 , wherein the at least one other system is the HVAC system.
6. The window control system of claim 5 , wherein a building management system is configured to control the HVAC system, and wherein the API is configured to permit the window control system and the building management system to communicate.
7. The window control system of claim 1 , wherein the at least one other system is the lighting system.
8. The window control system of claim 1 , wherein the window control system and the at least one other system are configured to provide data obtained or generated by the window control system to the at least one other system.
9. The window control system of claim 1 , wherein the window control system and the at least one other system are configured such that the window control system controls one or more devices of the at least one other system.
10. The window control system of claim 1 , wherein the window control system and the at least one other system are configured such that the at least one other system controls one or more devices of the window control system.
11. The window control system of claim 10 , wherein the devices of the window control system comprise a sensor and/or an optically switchable window.
12. The window control system of claim 11 , wherein the at least one other system comprises the HVAC system or the lighting system.
13. A method, comprising:
controlling an optical state of one or more optically switchable windows in a building with a window control system; and
with the window control system, interacting directly, by way of an application programming interface (API), with at least one other system of the building selected from at least one member of the group consisting of a lighting system, a heating, ventilation and air conditioning (HVAC) system, a security system, and a home appliance control system, the group excluding a building management system of the building.
14. The method of claim 13 , wherein interacting directly with the at least one other system includes:
(i) receiving a first communication from the at least one other system, wherein the first communication has a format specified by the API for communicating between the window control system and the at least one other system;
performing, at the window control system, one or more operations using instructions and/or data contained in the communication; and/or
(ii) transmitting a second communication to the at least one other system wherein the communication has a format specified by the API for communicating between the window control system and the at least one other system, wherein the at least one other system performs one or more operations using instructions and/or data contained in the communication.
15. The method of claim 14 , wherein the window control system comprises a plurality of electrochromic windows in electrical communication with one or more window controllers configured to communicate over a network.
16. The method of claim 13 , wherein the at least one other system is the home appliance control system.
17. The method of claim 13 , wherein the at least one other system is the HVAC system.
18. The method of claim 14 , wherein a building management system is configured to control the HVAC system, and wherein the HVAC system receives the first communication from the window control system via the API.
19. The method of claim 13 , wherein the at least one other system is the lighting system.
20. The method of claim 14 , wherein the at least one other system receives the first communication from the window control system, and wherein the first communication provides data obtained or generated by the window control system.
21. The method of claim 14 , wherein the at least one other system receives the first communication from the window control system, and wherein the first communication comprises instructions from the window control system for controlling one or more devices of the at least one other system.
22. The method of claim 14 , wherein the window control system receives the first communication from the at least one other system, and wherein the first communication comprises instructions from the at least one other system for controlling one or more devices of the window control system.
23. The method of claim 22 , wherein the devices of the window control system comprise a sensor and/or an optically switchable window.
24. The method of claim 23 , wherein the at least one other system comprises the HVAC system or the lighting system.
