ZigBee smart switch is a single-fire line power supply module known for its extremely low power consumption. It's primarily designed for single-fire line intelligent switches, such as ZigBee-based ones, and may not always be tested thoroughly. This innovative technology allows users to control various types of lighting loads—like LED, incandescent, fluorescent, and tungsten lamps—through a single-fire wired system.
The ZigBee Smart Switch (Single FireWire) operates on the ZigBee protocol and is built to work with a single-fire switch. It enables remote control via a mobile phone when paired with the appropriate host, making it easy to manage your home lighting from anywhere. Its self-organizing network feature ensures seamless connectivity, offering a convenient and wireless experience in your living space. It's suitable for homes, offices, hospitals, and hotels.

This ZigBee intelligent switch is compatible with traditional switch installation methods. There’s no need to cut into walls or modify existing wiring—simply replace the old mechanical switch. It can be operated manually or remotely without interfering with other devices. It's user-friendly, especially for elderly and children, and supports touch control, remote control, and intelligent remote control with real-time status feedback.
The ZigBee smart switch uses multi-channel power supply technology, which reduces standby power consumption and eliminates the need for primary and secondary power divisions. This design prevents situations where a single lamp failure could render the entire system unusable.
ZigBee smart switch represents a breakthrough in smart home technology. What makes it truly remarkable is its ability to achieve true single-fire power-taking technology, breaking through technical barriers that once limited its application.
A genuine ZigBee single-fire smart switch doesn't require any "safety capacitor," which helps avoid issues like flickering at both ends of the load's zero line.

In China, most switches are wired with a single live wire. Traditional smart home switches typically require an additional wire for power, leading to the need for rewiring during installation. This often means breaking walls and extensive construction, which is inconvenient for those who have already finished their renovations.
To address this, many smart home manufacturers are exploring single-fire power-taking technology. While using just the original two-wire setup might seem simple, there are underlying challenges. When using a single-fire smart switch, the smart switch and the lamp are connected in series. If the current is too low, the switch may not function properly; if it's too high, the lamp may flicker or fail to turn off completely. Incandescent lamps, in particular, may still show a faint glow, creating a red wire phenomenon.
These issues are more than surface-level. The change in load current can cause instability in the switch's control circuit, affecting the reliability of remote control. The interference from single-fire power supply can also lead to unstable signal range for smart devices.
Because of these unique working conditions, single-fire smart switches demand stricter energy efficiency standards for both standby and operation. The idea of simply using a single fire wire isn't as straightforward as it sounds. As of now, this remains one of the biggest technical challenges in the development of single-fire line smart products globally.
