Linked Device Groups

Almost every American home has 2-way or 3-way switches. where a light is controlled by 2 or 3 (or more) switches.

That tradition must be respected in the most intuitive way in Libre Home. After all, our system is designed to make every sense!

What is Linked Device Group

In short, it is about how a load device can be controlled with many buttons.

Buttons can be on your wall plate, or on your remote, or buttons from other brands.

Load device can be light, thermostat, TV and speakers, security alarm etc.

We ensure our system make every sense. You just group them together in one “friend circle”. It will automatically and magically works!

Device Link Group

How To Use

A group always only contains exactly one load device.


Click “Add Group” add new group.

Click “Add Linked” to add a button that controls the load.


User your finer to swipe left to delete an item.

Load and Non-load Devices

In Libre Home, a device can be either a load or non-load device. A load device can be a light (on/off or dimmable) or a speaker. Load is a device that consumes power and actually does works. A non-load device only send signals to load devices to control them.

A Linked Device Group always contains one and only one single load, and 1 or more non-load devices. Take multi-way switches as an example, there is always one load, and many other devices that send the control signal to the load device.

Just Use It! It is Our Job to Do it Right!

For users convenience, we enforced certain rules. For example, a thermostat can only be controlled with buttons on a Libre Remote, because the Libre Remote has a screen that can display mode and current/desired temperatures. An in-wall button without a screen will be difficult to feedback thus will be banned to be linked to a thermostat.

How Do I Control 2 Lights with 1 Button?

Combined with our patented Liberty-IoT-OS and Libre-App, everything is simple.

The trick is to combine multiple devices in one single “virtual device”. Even the state calculation can be customized at will.

For more information, please refer to “Libre Virtual Devices”.

Device Group State

Assuming a dimmer is linked to 3 in-wall switches, and 2 remotes. Once the dimming level changes, no matter how, through wall switch, remote or through your Smartphone, the level will be reflected correctly on all linked devices.

No need to know how it works. It’s our job to do it right.

Remote Configuration

Libre Home system may have many remotes. Remotes can be part of Linked Groups where a remote can control many devices.

By default, we randomly assign remote buttons to devices. We also take default device name and icon and wirelessly burn then into remote, so that the name and icon can be displayed on remote screen (when you press navigation button on remote).

Users are given a chance to manually configure every remote before submitting Linked Device Group.

Remote Buttons

Split and Merge

Certain buttons on remote have 2 contacts per button (up and down). Those buttons can be split into two single buttons. Split buttons can be merged back into one button.

Remote Config Remote Config

See images above, user can link a remote button to one of linked devices. The button then becomes a shortcut button to control that device.

A link can be reset in the future.


Once a button is linked to a device, it may be further customized.

For example, for a dimmer device, “On Level”, “On Transition Time”, “Off Transition Time”, “Default Move Rate” can be customized for the linked remote button.

Remote Display

Click “DEVICES” button on top brings up remote display screen.

There are several reasons remote display shall be used.

  • Thermostat control needs to display temperatures and modes.
  • Remote only has limited buttons. However more devices can be controlled. For devices without shortcut button binding, they need to be slected from menu.
  • User may want to check device state from remote screen (e.g. light level or speaker volume level).

The device name, icon and display order can be customized in this screen.
