Self-contained ec igu

A network of electrochromic windows, the network comprising:

• a plurality of electrochromic windows, each electrochromic window comprising
• at least one electrochromic pane,
• at least one additional pane,
• a sealing separator positioned between the electrochromic lite and the additional pane, and
• a window controller positioned on the electrochromic pane or as part of an assembly of the electrochromic window, the window controller comprising logic for controlling the electrochromic lite and communication logic for wirelessly communicating with other electrochromic windows on a self-meshing network.

An insulated glass unit (IGU) comprising:

• at least one electrochromic lite oriented in a first plane;
• at least one additional lite oriented in a second plane parallel to the first plane;
• a sealing separator positioned between the electrochromic lite and the additional pane;
• a sealed interior region between the electrochromic lite and the additional pane, wherein a perimeter of the sealed region is defined by the sealing separator;
• a window controller comprising logic configured to control the at least one electrochromic pane,
• wherein the window controller is positioned between the first plane and the second plane, wherein the window controller is not positioned within the sealed interior region, and wherein the window controller is physically accessible by an installer during installation of the IGU.
