H. What Can I Do With My FlexFob?

Before you begin using your FlexFob, and to get the most out of your purchase, you should be familiar with how the FlexFob’s programmable buttons work, and what your FlexFob can do. The FlexFob has four programmable, customizable (“flexible”) buttons. You operate the buttons by either a short press or a long press, each of which can result in a different response or action. The response/action depends on the programming settings of the button, of course.

In addition to YoLink-specific functions, referred to as “behaviors”, (like controlling a YoLink device or scene), the FlexFob can also be used with third-party applications, including Alexa routines, IFTTT applets, and with Home Assistant (like controlling a Lutron brand light switch or a Roomba robot vacuum cleaner). Please note: the button functions available to these third-party applications are in addition to the YoLink-specific functions (for example, a press of button 1 might control a YoLink smart plug as well as activate an IFTTT routine). For more information on using your FlexFob with one or more of these third-party applications, refer to page 27.

Your FlexFob can directly control compatible YoLink devices, such as siren products, plugs, light switches and locks, using Control-D2D, our unique device-to-device pairing feature. Control-D2D works directly with the controlled device, without internet and without the app. This can be convenient for use at locations where there is no YoLink wireless network (no hub nearby), such as for use in a boat or RV or at a remote location. Each button can be paired with up to 128 devices! For instructions on using the Control-D2D feature with your FlexFob, refer to page 31.

As opposed to Control-D2D pairing, the FlexFob can control one or more devices via settings in the app. Using the app gives you additional options, such as adding a delay between actions.

Your FlexFob can also activate a scene. A scene is a type of automation that starts on your (manual) command. Where most automations are triggered (started) by something happening, like a door opening or time of day, a scene is typically is triggered by you pressing a button on the app or on a fob (or via voice command to Alexa or Google assistants, etc.). Instructions for using the FlexFob to control a scene, refer to page 19, after familiarizing yourself with the following section, FlexFob App Settings.

Your FlexFob can enable or disable an Alarm Strategy. It can also modify an Alarm Strategy. An example of modifying an alarm strategy would be to temporarily disable SMS notifications on an active strategy. An example of enabling a strategy is to enable the Away strategy, which arms your security devices. Instructions for using the FlexFob with Alarm Strategies, refer to page 23, after familiarizing yourself with the following section, FlexFob App Settings.

Your FlexFob can send a manual notification. For example, pressing a button can send a specific message via SMS, and it can play a message over your SpeakerHubs. Instructions for using the FlexFob to send a notification, refer to page 24, after familiarizing yourself with the following section, FlexFob App Settings.

J. FlexFob Settings: Device Control

To control one or more YoLink devices, you have several options, including controlling one or more devices by assigning them to one of the buttons via app settings, by activating a scene (that might include taking an action on one or more devices), and by using Control-D2D pairing. This section covers the first method – controlling one or more devices by assigning them to a button via app settings.

The devices you wish to control must have already been bound (added to) your app account. Decide on a button to assign to controlling the device or devices. You can also decide to use one button to turn the device(s) on, and another button to turn them off, or you can use the click (short-press) action to turn them on and the long-press action to turn them off (or vice versa). The steps are very similar.

In the app, after deciding on the button to use for the on or off action, open the fob’s main screen.
Tap Edit Fob. The fob button programming screen is displayed
Select the appropriate button by tapping 1, 2, 3 or 4 (on the top of the screen). The selected button will have the number underlined.
To use the click/short-press function of the button, tap the + button in that section. Otherwise, tap the + button in the long press section.
Tap Device Actions. The Choose and Set screen opens.
Find and select your first device by tapping on it. Depending on the device type, you will be presented with options such as Lock or Unlock, Turn ON or Turn OFF. Tap the selection that is appropriate for you.
Tap the check mark (upper right corner) to confirm your selection.
Add additional devices and select their operation as needed. When finished, from the Choose and Set screen, tap the check mark (in the upper right corner).
You are returned to the fob’s button settings screen. Review your new device action(s) here.

Swipe left on a behavior to delete it. Or tap the delete (trashcan) button to delete all behaviors for that click or long-press behavior. You can use the sort button to edit the order of the behaviors.
If you are happy with the settings, you can assign an action to the other button behavior, and repeat the steps to assign devices to and actions to this button. Otherwise, tap the Save button.

It’s always a good idea to test any new settings, so they work properly for you when needed!

K. FlexFob Settings: Scenes

Before you can assign a scene to a button, you must first have created the scene. Here are some simplified instructions for creating a scene:

In the app, from the Favorite or Rooms screen, tap the Smart button (on the bottom bar of the app).
The Smart screen is displayed. This screen has two parts or tabs, the Scene tab, on the left, and the Automation tab (on the right). The selected or active tab is underlined. If it is not already, tap Scene (near the top).
Tap the + button (upper right corner) to create a new scene.
Tap the Name region and follow the instructions to name your new scene.
You can assign an icon to the scene by tapping in the Icon region.
Mark this scene as a favorite by tapping on the favorite (heart) button.
You can leave the Group setting as-is, for now.

To add behaviors to your new scene, tap the green + button.

Tap Device Actions to control one or more devices.
Tap Delay to add a pause between behaviors.
Tap Alarm Strategy to enable or disable or modify a strategy.
Tap Notification to send a notification to you or an account member, and/or to play a message over one or more SpeakerHubs.
Tap Filter to add a step that can abort or continue the next behavior based on the status of a scene or of a device. For example abort this scene (to switch the thermostat mode to Cool) if a window is open.

9. Tap the check mark to save each action, then review your scene.

10. If the scene settings are complete and correct, tap the check mark to save them, then tap the left arrow to exit this screen. (Refer to the previous section for tips on editing the behaviors)

Your new scene is now shown. You can tap on the edit button (pencil) to edit it, or you can tap on the run/play button to activate it.

Recently activated scenes are identified by dark green and square (instead of round) icons. This let’s you know which scene is active (such as your “Armed” scene) or if it was a temporary/momentary scene, this indicates the most recently activated scene.

To assign a scene to a FlexFob button, follow these steps:

Open the fob’s main screen. Tap the Edit Fob button.
Select the button for this scene, and tap the + button on the appropriate button behavior (click/short-press or long-press)
Select the Scene option. Select your scene, then tap Execute Scene.
Tap Confirm to approve your selection.
Review your settings. Tap the Save button to save, or Cancel to exit without saving (or you can tap the Delete button, or left swipe on the behavior to delete it).

As noted previously, it’s always a good idea to test any changes you’ve made to devices or to the app.

L. FlexFob Settings: Alarm Strategies

You can use your FlexFob to enable or disable or edit an Alarm Strategy. (It is not in the scope of this user guide to cover Alarm Strategy creation and settings. Please refer to product and app support resources to familiarize yourself with Alarm Strategy settings.)

Open the fob’s main screen. Tap the Edit Fob button.
Select the button for this strategy action, and tap the + button on the appropriate button behavior (click/short-press or long-press)
Select the Alarm Strategy option. Select your strategy, then tap either Enable Alarm, Disable Alarm or Advanced Settings.
Tap Confirm to approve your selection.
Review your settings. Tap the Save button to save, or Cancel to exit without saving (or you can tap the Delete button, or left swipe on the behavior to delete it).

M. FlexFob Settings: Notifications

You can actually send yourself or other account members a notification (such as a phone push notification, SMS or email). But you can also, if you have a SpeakerHub, have it play an attention-getting tone, followed by it playing your message via text-to-speech. An example of is a caregiver can be notified if assistance is needed getting out of bed.

In this example, we will create a garage door status checker, that will play a message, only if the door is closed. This will demonstrate the Filter behavior – a behavior that can check the status of a device or scene, before it proceeds to the next behavior.

Open the fob’s main screen. Tap the Edit Fob button.
Select the button for this action, and tap the + button on the appropriate button behavior (click/short-press or long-press)
Select the Filter option. Tap Set Condition.
Tap Check Device. Tap Continue.
Select your Garage Door Sensor. Tap Closed.
Tap Continue if condition is met. This means the automation will proceed to the next step only if the garage door is closed. If you selected Break if condition is met, the automation would abort (stop, doing nothing further) if the garage door is closed.
Tap Confirm.
Tap the + button again to add another behavior to this button.
Select Notification.
There are two settings here. The Alarm Strategies setting determines how this notification will be sent out. The selected strategy is identified in green text. If this strategy is not correct, tap the strategy name and select a new strategy in the dialogue box that appears. Then tap Confirm.
To define the text of the notification, tap the Notification Content box and type in your message.
Tap Save.
Review your settings. Tap the Save button to save, or Cancel to exit without saving (or you can tap the Delete button, or left swipe on the behavior to delete it).

When you press this button, if the garage door is closed, you will receive notifications (push, SMS, email) with the message “The garage door is closed” and if you have a SpeakerHub, this message can be read out to you.

N. FlexFob Settings: Alexa

You can use the FlexFob to trigger Alexa routines. You must have the Alexa app installed, the YoLink skill installed and connected to your YoLink app account.

Alexa regards the FlexFob’s four buttons as motion sensors. Only the short-press/click button behavior is recognized by Alexa (you can still use the long-press behavior for other things as Alexa ignores it) and in fact, you can still assign a YoLink app function to this button (although you are probably unlikely to need to do this). It is not in the scope of this user guide to cover set up of the Alexa skill or to cover creating an Alexa routine, so the following simplified instructions are provided:

Create a new routine in the Alexa app.
In the When This Happens section, select Smart Home.
Find your FlexFob. Each button is identified with an “_1, _2, _3,_4” appended to your FlexFob’s name. Select the button that you’d like to assign to this routine.
Tap the Detected button. Disregard the other settings available.
Tap Next.
Add whatever action(s) you require for your routine, such as turning on a non-YoLink device.
Review your routine settings. If they are correct, tap Save.

New settings in the Alexa app can take several minutes to take effect, but test your new routine by short-pressing on the appropriate FlexFob button.

O. FlexFob Settings: IFTTT

You can use the FlexFob to trigger IFTTT applets. You must have the IFTTT app installed, the YoLink service installed and connected to your YoLink app account.

Please note, IFTTT.com is a paid service, typically offering 5 free applets.

Create a new applet in the IFTTT app.
For the If This section, search and select the YoLink service.
Tap Flex Fob.
In the Device drop-down box, select your FlexFob, tap Done.
In the Button drop-down box, select the button. Tap Done.
In the Action drop-down box, select either Press or Long Press. Tap Done.
Tap Create Trigger to define the applet actions to be assigned to this button.
Tap Continue to save your settings.
Review your applet settings, if they are correct tap Finish.

Test your new applet by short- or long-pressing on the appropriate FlexFob button.

P. FlexFob Settings: Home Assistant

At the time of publication of this user guide, Home Assistant support for the FlexFob will be included in the next update. Refer to the Home Assistant website and the YoLink integration page for instructions.

Programmers and developers are encouraged to join us on Discord. Sign up here: https://shop.yosmart.com/pages/get-connected

Q. FlexFob Settings: Control-D2D

As noted previously, you can use Control-D2D pairing to pair a FlexFob button to one or more (up to 128!) compatible YoLink devices. Once paired, you will be able to control the device without the need of an internet connection or a hub.

Each Control-D2D pairing consists of one device that initiates the action, referred to as the “controller”. The device(s) that are controlled are called the “responder”. The FlexFob can only be a controller.

In this example, instructions are given to pair your FlexFob to a YoLink Garage Door Controller.

On the FlexFob, select a button. Press and hold this button for 5 to 10 seconds, until the LED flashes green, then release the button.

Press for 5-10 Seconds Until the LED Flashes Green
On the Garage Door Controller, press and hold the SET button for 5 to 10 seconds, until the status LED flashes green

Press for 5-10 Seconds Until the LED Flashes Green

Your FlexFob is now paired to your Garage Door Controller. Pressing the FlexFob’s paired button will now operate the garage door.

The process of pairing other YoLink devices is similar. Please refer to the device’s documentation for specific instructions.

Unpair your FlexFob:

On the FlexFob, press the assigned button for 10 to 15 seconds, until the LED flashes green, then red, then release the button.
On the Garage Door Controller, press and hold the SET button for 10 to 15 seconds, until the status LED flashes green, then red.

The Garage Door Controller should no longer respond to the FlexFob. Test the fob and perform the unpairing steps again, if needed.

R. Battery Replacement

Using a small Phillips screwdriver, remove the housing screw. Carefully place it to the side.
Remove the back shell.

You may find it easier to pry open the case using a fingernail, or a slotted screwdriver. Start at the bottom of the fob, at the keyring loop. Once part of the case begins to separate, move your fingernail or screwdriver gently around the edges of the case, until the back cover comes free.
Remove the old batteries.
Install two new alkaline AAA batteries. (Do not mix old and new batteries)
Reassemble the fob and tighten the screw.
Test the operation of your fob.

S. Firmware Updates

Your YoLink products are frequently being improved, with new features and functions added over time. It is periodically necessary to make changes to your fob’s firmware. For optimal performance of your fob, and to give you access to any improvements made to your fob’s model, these firmware updates should be installed (added to your fob) when they become available.

In the Detail screen of your fob, you will see the Firmware section, as shown in the image below. A firmware update is available if it says “#### ready now” (where #### is a four-digit combination of letters and/or numbers).

Tap in the Firmware area to start the update. The fob will update automatically, indicating the progress by percentage complete. You may use your fob during the update process, as the update is performed “in the background”. You may see the LED slowly blink green during the update, and the update may continue for several minutes beyond the LED turning off.

Firmware is like settings in your fob that define the overall operations of the fob, for example, determining when and how the fob’s sounder should beep. These settings are added to the fob when it is manufactured, and they are periodically updated, as needed, to add improvements, new features, new integrations, etc, to your fob, as they become available. If you use your FlexFob without an associated YoLink hub, firmware updates can not be made on your fob.

T. Factory Reset

When directed by customer support, and/or as an attempt to resolve a problem with your fob, it may be necessary to perform a factory reset. Factory resetting your fob returns it to the factory default programming and settings. This is a simple process:

Hold the #4 button for 20 to 30 seconds, until the LED blinks red and green alternately, then release the button.

#4 Button
Press for 20 to 30 Seconds

Factory reset is complete when the LED stops flashing.

Pressing the button for longer than 30 seconds will abort the factory reset process.

Factory reset will not remove the fob from the app. The only way to remove the fob from the app is to delete it (in the app).

U. Troubleshooting

If your fob does not operate as expected, if the fob has worked before, but stopped working, check and replace the batteries, if needed. If the fob has not worked before, perform the pairing process as previously explained, then test the fob again.

If this does not resolve the issue, please contact our customer support department (see the contact info on the last page of this guide).

We recommend checking for and performing any available firmware updates before contacting customer support.

V. Warnings

For optimal performance and lifetime of your fob, please adhere to the following warnings:
