Embed a smart dimmer relay into a traditional dimmer to upgrade it to a smart dimmer without replacing the existing wall-mounted one. Then, you can control the wall-mounted dimmer with your app to adjust the brightness of the lights connected to it as needed. Designed with the phase-cut angle detection technology, the dimmer relays are compatible with most dimmers in the market. Help you upgrade traditional switches to smart ones that can be used to perform smart brightness adjustment. Adjust light brightness in specific scenarios to create a smarter home.
Scenarios
Smart upgrade
The solutions are tailored for users who want smart dimmers and are compatible with the existing wall-mounted dimmers and switches. Easily renovate bedrooms and living rooms with smart dimmer relays coupled with adjustable lights to implement smart light control and meet your household requirements.
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 smart dimmer relay stores your brightness settings for a lamp, so that you won't have to adjust its brightness again after 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.
Smart linkage
You can connect this dimmer actuator with other "Powered by Tuya" smart devices across brands and categories. You can define a scenario in the app to enjoy hands-free convenience, for example, to turn a dimmer actuator on automatically when your smart door is unlocked.
Solution Benefits
No-code development and quick mass production
Our no-code SoC solutions require no programming by yourself and no external MCU. You can complete app UI design, module selection, and hardware configuration in five minutes; complete demo development in eight hours; and start mass production in 15 days.
Wi-Fi + Bluetooth dual-mode module
Tuya's dual-mode module supports Bluetooth auto-scanning and fast pairing, providing a better user experience and facilitating network configuration. Without a Wi-Fi network, you can connect devices to your mobile phone via Bluetooth to implement offline control.
Smart upgrade of ordinary dimmers
You can install the smart dimmer relays in the switch boxes of the existing wall-mounted dimmers, without replacing them or changing your home decoration style. Allow you to upgrade traditional dimmers to smart ones that can be used to perform smart brightness adjustment. You can use both the app and conventional dimmer switch to adjust the light brightness independently. The adjusted brightness is synchronized between the app and the switch.
Smart brightness stabilization
You can flexibly set the brightness range for different types of adjustable lights as needed to stabilize and smooth brightness adjustment and avoid flickering when the brightness is too low or too high. The settings including the brightness range take effect on both the app and the dimmer.
Solution Functions
Remote control
You can remotely control the smart relays with mobile apps to turn on/off electrical appliances, such as the lights and fans, and check their on/off status anytime and anywhere. When leaving home for work, turn off all lights to save energy with one tap.
Voice control
You can control all your switches hands-free with a smart speaker, such as Amazon Alexa, Google Assistant, Baidu DuerOS. For instance, if you are preparing dinner in the kitchen, just say "Alexa, turn the kitchen light on" and the smart speaker will carry out your voice command.
Timer
You can set a specific timer to switch on/off your home lights. For example, you can set the time for turning off the light in your kid's bedroom at 10:00 p.m. to remind him/her that it's bedtime. 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.
Smart brightness adjustment
The dimmer relays support the brightness adjustment of LED lights designed with the silicon controlled rectifier (SCR) dimming technology and the conventional incandescent lights. The dimmer relays support stepless dimming and synchronized and independent control with the app and wall-mounted switches. You can use a dimmer relay to gradually light up or dim the light, making the process soft, natural, comfortable, and elegant.
Brightness memory
Regardless of whether you use the app or wall-mounted switch to adjust the brightness, the final brightness value of the light is saved in the memory of the dimmer relay. When the light is turned off or in the case of a power outage, the brightness value is not lost. When the power is restored, the light is turned up at the previously set brightness. The brightness memory feature ensures that lights are always turned on at the preferred brightness, and repeating adjustment is not necessary.
Brightness matching
You can set the lowest and highest brightness of a light in the app. Then, the dimmer relay can automatically apply the settings to the matching lights and smooth the brightness adjustment to avoid flickering. This can also prevent the lights from flickering or going out due to the misoperation of your kids, extending the lights' service life. This small feature can bring great convenience to your life.
