User Guide Conventions
The following icons are used in this guide to
convey specific types of information:
Very important information
(can save you time!)
Good to know info but may not
apply to you

02
Your FlexFob connects to the internet via a YoLink hub (Speaker Hub
or the original YoLink Hub), and it does not connect directly to your
WiFi or local network. In order for remote access to the device from
the app, and for full functionality, a hub is required.
This guide assumes the YoLink app has been installed on your
smartphone, and a YoLink hub is installed and online (or your
location, apartment, condo, etcetera, is already served by a YoLink
wireless network).

What Can I Do With My FlexFob?
H
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.

09
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.

10
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.

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. �
1. In the app, after deciding on the button to use
for the on or off action, open the fob’s main
screen.
2. Tap Edit Fob. The fob button programming
screen is displayed
3. 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.

button, tap the +button in that section.
Otherwise, tap the +button in the long press
section.

screen opens.
6. 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.
7. Tap the check mark (upper right corner) to
confirm your selection.
8. 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).

use the sort button to edit the order of the be-
haviors.

It’s always a good idea to test any new settings,
