[0044] Further, the gateway can control the color change of the EC glass according to the outdoor light intensity collected by the light sensor, or according to the outdoor temperature collected by the temperature sensor, or according to both the light and temperature.

[0045] According to the light transmittance characteristics of the EC glass, the embodiment can be divided into four color change gears, i.e., T1 light transmittance a%, T2 light transmittance b%, T3 light transmittance c%, and T4 light transmittance d%.
