Frequently-Asked Questions

I need to replace a 3-way switch with the smart in wall switch, is there a work around?

Yes, there are two solutions for replacing a 3-way switch with a YoLink In-wall Switch.

Solution 1: Use one YoLink In-wall Switch as the light control and another YoLink In-wall Switch as the mutual control device.

Install a YoLink In-wall Switch as the lamp switch (switch A) to directly control the lamp's on/off function.

Install one or more YoLink In-wall Switches to connect to the power supply only, then create a pairing relationship with switch A. These switches will act as control devices for switch A. You can find instructions for creating a pairing relationship between YoLink In-wall Switches on Page 18-23 of the user guide.

Solution 2: Use a traveler line to connect two YoLink In-wall Switches together through the Live terminal.

Install a YoLink In-wall Switch to connect directly to the lamp.

Install one or more YoLink In-wall Switches to connect the Live terminal through the traveler line. Each YoLink In-wall Switch needs to be connected to the neutral line.

Before installation, please refer to the installation part on Pages 6-10 of the user guide, and follow the manufacturer's instructions carefully to ensure proper installation and avoid any potential hazards.

Please note the following:

The maximum resistive load of the YoLink Switch is 10A/110V.

YoLink Switch is a single-bit switch, so if you use it to replace a multi-gang switch, the original multiple switch button control will become a switch button control, and no longer supports single button control by region.

If the multi-gang switch has multiple wiring harnesses connected to the lamp, they need to be connected to one terminal at the same time when replaced by a YoLink Switch. The standard specifications of the wire (the wire that can pass 10A current) may not fit into the screw together.

Is it possible to put 2 single YoLink switches in a double switch box?

Yes, it is possible to install two single YoLink switches in a double switch box.

To do this, you need to remove the existing wall plate and check the dimensions of the double switch box to ensure that it can accommodate two single switches. You may need to purchase a new double-wall plate that fits the dimensions of your double switch box and can accommodate two single switches.

 I have no neutral wire, will the in-wall switch work?

I'm sorry to inform you that the YoLink In-wall switch requires a neutral wire for installation.

The YoLink In-wall Switch is a zero-fire switch that can only be used with both neutral and live inputs. If your wiring setup only includes a hot line and does not have a neutral wire, the YoLink In-wall switch will not be compatible.

Please note that our product is not applicable for use with a single fire switch that only has a hot line and no neutral line.

The YoLink In-wall Switch is not working as expected. Is there a workaround?

Please follow these steps to troubleshoot the issue:

Confirm that the in-wall switch has been installed correctly by referring to the installation guide.

If the installation is accurate, press the power button on the switch and listen for a clicking sound. If there is no sound, it may indicate a problem with the switch.

Once you've checked these steps, please contact YoLink customer support with your findings. They will be able to provide further assistance and potential solutions for your situation.

 Can I control the YoLink In-Wall Switch remotely?

Yes, you can remotely turn the switch on or off using the YoLink app.

Does the YoLink In-Wall Switch have scheduling and timer functions?

Absolutely! The switch has both scheduling and timer functions, which can be set up through the YoLink app.

Can I create smart scenes and automations with the YoLink In-Wall Switch?

Yes, you can set up smart scenes and automations for the In-Wall Switch using the YoLink app.

 Is the YoLink In-Wall Switch compatible with voice assistants like Alexa and Google Assistant?

Yes, the switch works with both Alexa and Google Assistant, allowing you to use voice commands to control it.

Can I integrate the YoLink In-Wall Switch with IFTTT?

Yes, the switch works with IFTTT, enabling you to create custom applets for turning the switch on or off.

What is the maximum number of Controllers I can pair with a YoLink In-Wall Switch?

With YoLink Control, there is no strict limit to the number of Controllers you can pair with an In-Wall Switch. However, for optimal performance, we recommend linking up to 128 devices.

If there is a power outage and the power is restored, will the YoLink In-Wall Switch automatically turn back on?

You can customize the power-on behavior in the YoLink app. Go to the Device screen, tap the three dots in the upper right corner to access the Device Details screen, and select "Power on status." From there, you can set the switch to turn back on to its previous state (last state), turn all on, or turn all off.

Can YoLink switches be installed in a three-gang box, and if so, can I use a standard three-switch faceplate?

Yes, YoLink switches are designed to fit into a three-gang box. You can also use a standard three-switch faceplate for a seamless and clean installation.

How can I delete scheduled items in the YoLink app?

To delete a scheduled item in the YoLink app, simply swipe left on the schedule you wish to remove. This action will delete the selected schedule.

 Can I see the remaining time for the timer on the YoLink In-Wall Switch?

 Yes, make sure your YoLink app is up to date. The remaining time for the timer should be displayed on the device screen within the app.

Can you explain the purpose of the neutral wire required for the YoLink In-Wall Light Switch to function?

The neutral wire is an essential component in electrical systems, as it carries the circuit back to the original power source. The YoLink In-Wall Switch requires a neutral wire for proper operation, as it is designed for a live-neutral switch configuration and is not compatible with single live switches.

What is the difference between the schedule and timer functions in the YoLink app?

The timer function in the YoLink app is designed for one-time events, whereas the schedule function is for setting up recurring events. Both of these settings are saved in the device itself, allowing them to function even without an internet connection.

Why is the YoLink In-Wall Switch disconnect frequently?

There are two possible reasons:

Incomplete device status loading due to poor mobile phone network connectivity. Ensure that your mobile phone has a strong and stable network connection for optimal performance.

Insufficient interval time between device operations. If the device is operated too quickly or repeatedly, it may not fully respond, leading to connectivity issues. Ensure that the interval time between operations is more than 6 seconds to avoid this problem.

Can the YoLink In-Wall Switch work with other brand smart devices?

The YoLink In-Wall Switch offers remote control through the YoLink app, timer and scheduling functions, and the ability to create smart scenes and automation between the In-Wall Switch and YoLink sensors. It is also compatible with Alexa, Google Assistant, and IFTTT.

Does the programming work when the internet is down?

 If the internet is disconnected, remote control of the YoLink In-Wall Switch through the app will not work. However, schedules and timers saved in the device itself will continue to function. YoLink Control, which allows you to use the YoLink Remote to turn the In-Wall Switch on or off, can also operate without an internet connection.
