Based on the silicon-controlled rectifier (SCR) technology, the solutions are suitable for Wi-Fi dimmer switches powered with live and neutral (L&N) wires. They can be used to implement the smart upgrade of dimmable LED lights, most energy saving lamps, and all incandescent lamps. You can control the dimmer switch to turn a lamp on/off or adjust its brightness through a physical button or in the app.
Scenes
Smart upgrade
The smart dimmer switch is provided with the wiring diagram, installation panel, and necessary accessories. You can complete the wiring based on the schematic diagram. You can directly connect the dimmer switch to your Wi-Fi network and make an ordinary lamp smart without an intermediate device like a gateway.化。
Flexible brightness adjustment
The solutions enable you to set reasonable ambient lighting for any occasions, such as family dinner time, movie time, and reading time. When the power is off, the dimmer switch stores brightness settings for a lamp, so that you won't have to adjust its brightness again after it is powered on.
Convenient light grouping
You can connect ordinary lights of each room to a dimmer switch to form a light group and set the appropriate brightness for lights in this group. After you leave home, you can turn off all the lights at once to save power. When you come home, you can turn the lights on.
Leaving home mode
The automatic brightness-adjustment feature of the dimmer switches can help you set up your smart lighting system at home. For example, you can set the switches to periodically turn your lights on or off to make others believe that you are at home and keep intruders or thieves away.
Solution advantages
Dual-mode Wi-Fi + BLE module
Built with Tuya's dual-mode modules, the dimmer switches can scan Bluetooth devices and complete Bluetooth pairing at a high speed. Without a Wi-Fi network, you can connect the dimmer switches to your mobile phone to implement offline control.
Multiple functions and flexible configuration
The dimmer switches are designed with various functions, such as light on/off, timer settings, countdown timer, sunrise and sunset timers, power-on status and indicator light settings, and backlight on/off control. They can be designed with a rocker button, touch screen button, or knob button, and are provided with reference hardware schematic diagrams.
Ready-to-use modules for independent MCU development
Tuya provides ready-to-use hardware modules, all-in-one apps, and cloud services. Developers only need to focus on the R&D of the product functions, and use the MCU SDK, our all-in-one apps and panels to efficiently and conveniently complete the smart product upgrade.
Short development cycle and flexible upgrade
Developers who adopt MCU solutions embedded with Tuya modules can upload their MCU programs to the Tuya IoT Platform. Log in with their product accounts and perform OTA upgrades by themselves. The solutions allow developers to quickly locate, verify, and release patches for bugs, significantly shortening the firmware launch cycle.
Solution functions
Remote control
Control the dimmer switches to turn on or off the lights connected to them and check the status of the lights in the mobile app anytime and anywhere. After leaving home in the morning, you can check the status and brightness of the lights in your mobile app, and dim the lights or turn them off.
Voice control
You can connect the dimmer switches to smart speakers and control your lights with your voice. The dimmer switches support smooth connections with popular smart speakers such as Amazon Alexa, Google Assistant, and Baidu's DuerOS. You can use simple voice commands to control the switches and adjust your lights' brightness. For example, you can name the light in your study as Study Light in the app. When you want to read or work in your study, you can say, "Alexa, turn on the Study Light". If the light is too bright, you can say "Alexa, adjust the brightness to 90%."
Smart timer
You can set a specific timer to turn on/off your home lights. For example, you can set the timer to turn off the light in your kids' bedroom at 22:00 to remind them that it's bedtime. You can also set a timer to turn on the lights in the living room at 80% brightness at 18:00 to start a warm evening.
Countdown timer
The smart switch can be configured to turn on/off lights after a brief period to suit your habits. If you set the countdown timer at 15 minutes, the light would be turned off 15 minutes later to help you fall asleep.
Lowest brightness
You can set the lower brightness limit for your lights to prevent them from flickering or going out due to the misoperation of your kids. This can also ensure your lights will have a longer service life.
Sleeping and wake-up light
When the sun begins to rise in the morning, the light is slowly lit up along with the daylight. When you go to bed at night, the bedroom light dims out.
