1Loss of time
If traditional commissioning methods are used to associate electrochromic windows with controllers, then the process becomes time-consuming and error-prone, but implementing a new commissioning method requires additional system complexity and coordination overhead
Solution Approach 1:
The system performs preliminary actions by automatically generating and transmitting unique commissioning patterns to each controller before formal association. Each controller pre-configures its associated windows with distinctive identification patterns, enabling rapid matching during commissioning without manual intervention or complex coordination procedures.
Solution Approach 2:
The system creates visual copies of controller identities through light patterns displayed on the electrochromic windows. Instead of direct electronic association, the controller's unique identity is copied into visual form (light patterns) that can be easily observed and matched, simplifying the association process while reducing errors.
2Measurement precision
If manual association methods are used, then installation errors increase, but automated detection requires additional sensors and processing capabilities
Solution Approach 1:
The system utilizes light pattern changes on the electrochromic windows to encode controller identities. Each controller displays unique temporal or spatial light patterns on its associated windows, allowing precise visual detection and association. The electrochromic material's ability to change optical properties provides a built-in display mechanism without requiring additional sensors or complex detection infrastructure.

AI summary
Networks of electrochromic windows and methods of commissioning the windows on such networks are described. The commissioning may involve determining where each electrochromic window is installed and/or which controller is associated with which electrochromic window. In various cases, a number of windows may be simultaneously commissioned.
