This product only requires replacement of the lighting fixtures, no need to change the wiring. After replacement, you can adjust the brightness continuously from 0-100% and the color temperature from 2000K to 6000K through intelligent control terminals such as mobile phones or computers. The system is easy to install, just install intelligent control products on the existing lines to achieve the effect of "lights on when people come, lights off when people leave", and can automatically adjust the brightness of the lights according to the ambient light intensity. The system can also be extended to air conditioning equipment, automatically adjusting temperature and start stop based on changes in environmental temperature, humidity, and pedestrian flow. At the same time, physical switches are retained for easy manual control of lighting and air conditioning. A gateway can manage multiple controllers simultaneously and support partitioned ad hoc networks. The system has a self checking function, and local faults will not affect the normal operation of other devices in the network. At the same time, faulty devices will automatically alert and report repair information. Adopting an integrated millisecond level sensor for 24-hour uninterrupted monitoring of energy consumption. The energy consumption of all electrical equipment can be displayed in real-time and accurately on the terminal screen.
