The FlexSwitch is YoLink's smart wireless battery-powered single pole switch, with a relay capable of controlling electrical loads including lights, heaters, fans, motors, and pumps.
Longest Wireless Range: Powered by LoRa technology, the long-range yet low-power system offers the industry’s longest receiving range in the market (1/4 mile open-air). Our long-range coverage enables its use in areas challenging for most residential Wi-Fi systems, such as basements, outdoor porch/patio areas, sheds, free-standing garages, even remote outbuildings on your property.
Works With Alexa & Google Voice Assistants: Supercharge your YoLink system by adding the YoLink skill to Alexa or Google Assistant. Control your YoLink devices by voice command (“Alexa, turn off the light” – “OK!”) and control your YoLink devices as part of routines/automations that may include other, third-party, smart devices integrated with Alexa/Google.
Hassle-Free Installation: Install the FlexSwitch with ease, as it eliminates the need for a neutral wire. Simply power it with 2 AA batteries and enjoy a wireless switch solution that blends seamlessly into your home decor.
Long-Lasting Battery Life: Designed for longevity, the FlexSwitch operates up to 2.5 years on a single set of AA batteries, offering a maintenance-free experience and reducing the need for frequent battery replacements.
Precision Lighting Control: Tailor your home's lighting to your schedule with advanced timer functions, adjustable to the minute, and scheduling capabilities precise to the second, ensuring your lights are always just how you want them.
Enhanced Safety Features: Stay secure with the built-in over-temperature protection that activates at 70°C, safeguarding your home from potential electrical hazards while offering peace of mind.
Dual-Function Buttons: Buttons 1 and 2 double as fobs, providing additional flexibility and control options for your lighting needs.

Please note: YoLink Hub or SpeakerHub is required (see below).

No neutral wire required

Houses not built recently may not have neutral wires, and often even in homes with neutral wiring not all switch locations have a neutral wire. YoLink's FlexSwitch provides a way for you to have a smart, wireless switch without the need for neutral wires. 

Schedules and Timers

Create your personalized lighting schedules through scenes and automations and set timers for when to turn off and on your smart light switch.

Voice Control

Use your voice assistant like Alexa or Google Assistant to control lighting with the FlexSwitch.

Remote App Control

Control your lighting from your phone anytime, anywhere. 

Dual-Function Buttons

Set different behaviors for buttons whether through a button click or a long press, making it possible to also have different actions by the tap of a button, such as turning on our energy monitoring plug or starting a specific created scene. 

Integrate with Door/Motion Sensors

Use the smart light switch along with our door sensors to automatically control lights upon opening or closing, adding convenience and safety. Examples are closets, pantries, and garages. 

You can use automation to turn off your lights after a duration, or team up your door sensors and motion sensors, and turn off lights when motion is no longer detected.
