B. Introduction

The YoLink Dimmer Switch is a smart dimmer-style single-pole light switch, for 120 to 250 VAC circuits and dimmable light bulbs.

For full functionality, including functionality of the YoLink app, your smart Dimmer Switch connects to the internet by connecting wirelessly to one of our hubs (original YoLink Hub or the SpeakerHub), not via WiFi or other wireless methods. If you do not already have a YoLink hub, and unless there is an existing YoLink wireless network in your building (for example, an apartment complex or condo building with a building-wide YoLink system), please purchase and set up your hub before proceeding with the installation of your new Dimmer Switch.

Please note: the Dimmer Switch requires a neutral wire! It will not function without a neutral wire. As explained in the Installation section, you must identify the neutral wire in the switch’s electrical box. If a neutral wire is not present, one must be installed. Consult with or hire a qualified and properly licensed electrician, as required.

Also note: the Dimmer Switch is not compatible with 3-way switches or 3-way style wiring, but 3-way operation functionality can be accomplished using two YoLink Dimmer Switches, wired as standard switches, and paired using Control-D2D pairing. This pairing process is explained in the Control-D2D pairing section of this user guide.

Refer to the Before You Begin section for additional important information prior to installing your Dimmer Switch.

6. Ensure your YoLink Hub or SpeakerHub is setup and online before proceeding to the next step.

G. Installation

1. Turn off the circuit that serves the switch at the circuit breaker panel (or other means of disconnecting the AC power to the circuit). Do NOT work on “hot” electrical wiring!

   Verify that power has been removed to the light switch, by testing the switch, and by using a multimeter or other type of voltage tester before removing any wires from the switch.

   If replacing an existing switch, proceed to the next step. For new installations, skip ahead to step 5.

2. Using a slotted screwdriver, remove the switch faceplate, then using a slotted or Phillips screwdriver, remove the switch and pull it away from the wall.

3. Before removing any wiring from the switch, identify the wires on the switch and in the electrical box:

   Ground wire: this wire is typically a bare copper wire, but it may have a green jacket (insulation), or it may have another color insulation with green tape identifying it as a ground. Additional means of identification are the wire is terminated on (connected to) a green screw on the switch, and/or the screw or wire connection has a designation such as “GND” and/or includes the universal earth ground icon:

   Line or Hot Wire: this wire is typically black, but can be red or another color, but if not it may be marked as the hot wire with black or red tape. One of the wires on the existing light switch should be the hot wire. Another way of identifying this wire is that it may be connected to other wires in the box. If the box contains multiple switches, for example, there will typically be a hot wire that connects to each switch. Observe each of the non-ground wires on the switch, looking for connections to other black (or red) wires under a “wire-nut” or similar wire connector.

   Switch Leg Wire: this wire is typically black, but maybe red or another color. This is the wire that is energized when the switch is on. After you have identified the ground and the hot wires on the existing switch, the remaining wire should be the switch leg wire. This wire can also be helpful in identifying the neutral wire. While the existing switch you are replacing with the Dimmer Switch may not have required a neutral wire, the light that it controlled does require a neutral wire. Follow the switch leg wire to its connections to another wire, or for it to join a “multi-conductor” cable (a larger jacketed cable with two or more different conductors within it). If the switch leg wire is in a yellow jacketed cable, for example, that also has a white and a bare copper wire within it, this cable most likely serves the existing light, and you have also identified the neutral wire.

   Neutral Wire: this wire is typically white. As explained above, the light that is controlled by the existing switch will require a neutral wire, making it easier to identify if it is in the box. Otherwise, look for multiple white wires under one wire connector in the electrical box. If you find a white wire with black tape, this is likely a wire NOT used as a neutral; do not use this wire! If you are still unable to identify a neutral wire, stop and consult an electrician to have one installed, otherwise contact us regarding questions about returning your Dimmer Switch, if so desired.

4. Identify each wire with a marker, tape or other labeling method, as desired, so they are not confused with each other during the wire termination step.

5. Connect the Dimmer Switch’s “pigtail” wires (pre-installed colored wires, connected to the switch) to your identified wires. As shown in the example shown in Figure 1 below, and using the included or existing “wire-nut” connectors:

   Connect the switch’s green pigtail to the ground wire(s).

   Connect the switch’s white pigtail to the neutral wire(s).

   Connect the switch’s black pigtail to the hot wire(s).

   Connect the switch’s red pigtail to the light switch leg wire.

6. Check each wiring connection by gently tugging on each conductor, ensuring it does not pull out of the wire nut or appear loose. Re-do any that do not pass this test.
7. Gently push the wiring and the switch into the electrical box, then secure the switch to the box using the included or existing screws (if more suitable for the box).
8. Using the included screws, secure the faceplate mounting plate to the switch, then mount the outer part of the faceplate onto the mounting plate, snapping it into place. (If this switch is in a multi-gang box, use the existing faceplate or furnish one suitable for the switches in the electrical box.)
9. Turn on power to the circuit by returning the circuit breaker to the on position (or reconnect power per your applicable circuit disconnection method).
10. Test the switch by turning the light on and off.

P. About Control-D2D (Device Pairing)

YoLink Control-D2D (device-to-device) pairing is a feature unique to YoLink products. One device can be paired to one (or more) devices. When two or more devices are paired, a link is created, “locking-in” the behavior, so that the device(s) will carry out their paired behavior when required, regardless of a connection to the internet or cloud, and even without AC power (in the case of battery-powered or battery backed-up devices). For example, a Door Sensor can be paired to a Siren Alarm, so that when the door is opened, the siren is activated.

Several important points:

• The use of Control-D2D is entirely optional. It is more common to use the app’s automation and scene settings to create desired behaviors, such as motion sensors turning on the lights automatically. Your application may require functionality during the loss of internet/WiFi, in which case Control-D2D pairing may be preferred.

• The Dimmer Switch buttons will operate for on, off and dimming settings regardless of it being online or connected to the cloud.

• While online, any paired behaviors as well as automation and scene settings (desired switch behaviors set in advance by you, such as the motion sensor/light switch example) will both be carried out. Paired behaviors and app settings can coexist, but use care to not create conflicting actions between the two, as the device may not operate as desired.

• A device can have up to 128 pairings.

• A device that controls another device is referred to as a Controller. The device that is controlled is referred to as a Responder.

How to Pair Two Devices:

In this example, two Dimmer Switches will be paired to each other, to provide 3-way functionality.

1. Start with both switches off. Choose one switch to act as a Controller. Turn on the Controller, then press the power button for 5 to 10 seconds until the green LED flashes.

2. At the other switch (the Responder), turn the switch on. Press the power button for 5 to 10 seconds until the green LED flashes. After a moment, the LEDs will turn off.
3. Test your pairing by turning off both lights, then turning the Controller light on. The Responder light should then turn on (the switch will go to the last brightness level set). If not, repeat the pairing. If still not successful, follow the How to Unpair Devices section on the next page.
4. For 3-way type operation between these two switches, repeat steps 1 and 2, but for the switch that was originally the Responder. This switch will now act as a Controller.
5. Test your pairing, from both switches. Turning one switch on should result in both switches turning on. Turning either of the switches off results in both light switches turning off.

If replacing existing 3-way switches with Dimmer Switches, the wiring may not immediately be compatible with the Dimmer Switch. The “traveler” wire will not be connected to either Dimmer Switch, but it may need to be changed to another function (such as to a neutral wire), so that each switch has a hot, neutral, ground, and at least one switch leg wire going to the controlled light(s).

How to Unpair Two Devices:

1. Start with both switches off. Turn on the Controller device (in this case, either one of the lights that are now in a 3-way type pairing). Press the power button for 10 to 15 seconds, until the LED flashes orange. Note: the LED will flash green prior to the 10 second mark, going into pairing mode, but keep pressing until the LED flashes orange. The Controller’s pairing is now removed. This switch will no longer control the other switch, but the other switch’s pairing is unchanged.

2. To remove the other switch’s paired behavior, repeat the steps just used for the first switch. Test both switches to ensure that they no longer control or respond to the opposite switch.

These instructions can be applied to other devices, but the LED color and flash behaviors can vary between models.

Generally, when pairing, the Responder should begin in the state (on/off or opened/closed or locked/unlocked) that it should change to when the Controller is activated.

Q. Firmware Updates

Your YoLink products are constantly being improved, with new features added. It is periodically necessary to make changes to your device's firmware. For optimal performance of your system, and to give you access to all available features for your devices, these firmware updates should be installed when they become available.

In the Detail screen of each device, at the bottom, you will see the Firmware section, as shown in the image below. A firmware update is available for your device if it says “#### ready now” - tap in this area to start the update.

The device will update automatically, indicating progress by percentage complete. The LED light will slowly blink green during the update and the update may continue for several minutes beyond the LED turning off.

R. Factory Reset

Factory reset will erase device settings and restore it to factory defaults.

Instructions:

Hold the SET button down for 20-30 seconds until the LED blinks red and green alternatively, then, release the button, as holding the button longer than 30 seconds will abort the factory reset operation.

Factory reset will be complete when the status light stops blinking.

Only deleting a device from the app will remove it from your account
