Self-contained EC IGU
Onboard EC window controllers are described. The controllers are configured in close proximity to the EC window, for example, within the IGU. The controller may be part of a window assembly, which includes an IGU having one or more EC panes, and thus does not have to be matched with the EC window, and installed, in the field. The window controllers described herein have a number of advantages because they are matched to the IGU containing one or more EC devices and their proximity to the EC panes of the window overcomes a number of problems associated with conventional controller configurations. Also described are self-meshing networks for electrochromic windows.
1. A method of determining associations between electrochromic windows and associated window controllers installed in a network, the method comprising:
(a) triggering an electrochromic window to cause its associated window controller to send a signal with identifying information about the electrochromic window,
wherein the signal is sent from the associated window controller upstream to a network controller, and
wherein triggering the electrochromic window comprises one or more of the following:
(i) shining a light on a light sensor,
(ii) blocking or disrupting a light sensor,
(iii) blocking or disrupting a motion sensor, and/or
(iv) blocking or disrupting an occupancy sensor; and
(b) determining the association between the electrochromic window and its associated window controller by comparing which electrochromic window is triggered and which associated window controller sends the signal.

8. The method of claim 1 , wherein triggering the electrochromic window to cause its associated window controller to send the signal comprises shining the light on the light sensor.
9. The method of claim 1 , wherein triggering the electrochromic window to cause its associated window controller to send the signal comprises blocking or disrupting the light sensor.
10. The method of claim 1 , wherein triggering the electrochromic window to cause its associated window controller to send the signal comprises blocking or disrupting the motion sensor.
11. The method of claim 1 , wherein triggering the electrochromic window to cause its associated window controller to send the signal comprises blocking or disrupting the occupancy sensor.
12. The method of claim 1 , wherein (b) comprises recording a physical location of the electrochromic window that was triggered.
13. A method of determining associations between electrochromic windows and associated window controllers installed in a network, the method comprising:
(a) triggering an electrochromic window to cause its associated window controller to send a signal comprising identifying information about the electrochromic window,
wherein the signal is sent from the associated window controller upstream to a network controller, and
wherein triggering the electrochromic window comprises one or more of the following:
(i) shining a light on a light sensor,
(ii) blocking or disrupting a light sensor,
(iii) blocking or disrupting a motion sensor, and/or
(iv) blocking or disrupting an occupancy sensor;
(b) receiving and displaying the identifying information in an application or program; and
(c) associating the electrochromic window that was triggered with its associated window controller in the application or program based on which electrochromic window was triggered and the identifying information displayed in the application or program.
14. The method of claim 13 , wherein the network controller sends the identifying information to a master controller.
15. The method of claim 14 , wherein the master controller sends the identifying information to the application or program.
16. The method of claim 13 , further comprising repeating (a)-(c) on different electrochromic windows installed on the network.
17. The method of claim 13 , wherein the signal comprises an address of the electrochromic window on a CAN bus system.
18. The method of claim 13 , wherein the signal comprises a unique serial number of the electrochromic window.

20. The method of claim 13 , wherein the signal comprises information regarding properties of an electrochromic device on the electrochromic window.
21. The method of claim 13 , wherein the signal comprises information regarding parameters to be used when transitioning an electrochromic device on the electrochromic window.
22. The method of claim 13 , wherein triggering the electrochromic window to cause its associated window controller to send the signal comprises shining the light on the light sensor.
23. The method of claim 13 , wherein triggering the electrochromic window to cause its associated window controller to send the signal comprises blocking or disrupting the light sensor.
24. The method of claim 13 , wherein triggering the electrochromic window to cause its associated window controller to send the signal comprises blocking or disrupting the motion sensor.
25. The method of claim 13 , wherein triggering the electrochromic window to cause its associated window controller to send the signal comprises blocking or disrupting the occupancy sensor.
26. The method of claim 13 , wherein triggering the electrochromic window to cause its associated window controller to send the signal comprises placing a magnet near a sensor.
