Monitoring sites containing switchable optical devices and controllers

A non-transitory tangible computer readable medium having stored thereon software instructions that, when executed by a processor of a portable user device, cause the processor to control transmittance levels of a plurality of optically switchable devices, by:

• generating a display on a touch screen interface of the portable user device, the display showing a physical arrangement of the plurality of optically switchable devices, the touch screen interface being configured to allow a user to make a selection of which of the plurality of optically switchable devices are to be adjusted;
• receiving the selection of which of the plurality of optically switchable devices are to be adjusted;
• and
• generating wireless control signals for adjusting the selected optically switchable device of the plurality of optically switchable devices.

A window control system comprising:

• a plurality of optically switchable devices;
• a portable user device for generating wireless control signals, wherein the portable user device includes a touch screen user interface configured to allow a user to select which of the plurality of switchable optical devices are to be adjusted;
• and
• a plurality of window controllers each coupled to a respective one of the plurality of optically switchable devices, by way of at least one receiver and transmitter, wherein each of the plurality of window controllers is configured to:
• communicate wireless control signals with the portable user device via the at least one receiver and transmitter;
• and
• adjust an optical characteristic of a respective one of the plurality of optically switchable devices in response to the wireless control signals.
