One App for 2500+ Smart Home Brands: LinknLink Setup Guide
A connected home should feel easier to manage, even when its lights, climate devices, curtains, locks, sensors, cameras, TVs, and appliances come from different brands. The new LinknLink App is designed to bring supported devices from 2500+ brands into one organized experience across different protocols and ecosystems.
This guide focuses on that multi-brand value: how to build a clean room structure, connect Home Assistant, add IR and RF appliances, and use Agent+ without rebuilding every working automation.
Why Multi-Brand Smart Homes Become Hard to Use
Most smart homes grow one purchase at a time. A thermostat brings one app, a camera another, a TV another, and a new lighting system adds a separate account. The devices may all be smart, but the household still has to remember which app controls which room.
Too many control surfaces
Each added brand can bring another menu, naming system, notification model, and account.
Inconsistent rooms
The living room can appear several times, while each app sees part of it.
Automations lose context
Presence, climate, IR, RF, and scenes cannot help one another when they stay isolated.
What 2500+ Brand Support Means in Practice
LinknLink brings supported devices from 2500+ brands into a common app experience. Controls vary by product, model, protocol, region, firmware, and integration. A light may expose brightness and color, a camera may expose viewing and status, and an older AC may join through an IR controller. The practical benefit is a consistent navigation model for the devices and scenes your household uses.
The Unified Control Layers
| Layer | Role | Examples | LinknLink path |
|---|---|---|---|
| Everyday app | Room cards, scenes, natural control, remote access, and diagnostics. | Lights, climate, curtains, sensors, cameras, and routines. | LinknLink App + Agent+ |
| Local automation | Entities, helpers, MQTT, advanced rules, and private automation logic. | Occupancy helpers, schedules, local scenes, and state machines. | HomeClaw or an existing Home Assistant system |
| Room context | Presence and environmental signals that explain what a room needs. | Occupancy, 60GHz presence, temperature, and humidity context. | eMotion Air, Pro, or Ultra |
| Legacy appliance bridge | Turns infrared or radio-frequency remotes into repeatable scenes. | AC, TV, fan, projector, shades, and RF outlets. | eRemote HA, eHome HA, eMotion Pro, or eMotion Ultra |
Set Up One Home Before Connecting More Devices
Importing too many devices at once can make a new setup harder to review. Start with one home, two or three important rooms, and the devices people control most often.
Create a clear home and room structure
Use names people already say: Living Room, Main Bedroom, Kitchen, Entry, Garage, and Office. Avoid protocol names in room labels.
Connect one ecosystem at a time
Add supported devices in small groups. Confirm basic control and state reporting before adding the next brand.
Rename devices for natural requests
Use names such as Living Room AC or Bedroom Reading Light. Clear names make room cards and Agent+ requests more predictable.
Expose useful Home Assistant entities
Keep diagnostic helpers and technical entities in Home Assistant. Put family-facing controls, scenes, and room states in the app.
Test one cross-brand scene
Build one reversible scene that combines two brands, then confirm manual control and failure behavior before expanding.
Use Home Assistant Without Bringing Complexity into Each Room
Home Assistant can remain the local logic layer for MQTT devices, helpers, automations, and integrations. The LinknLink App can become the everyday layer that family members see. This division keeps advanced control available without turning room cards into an engineering dashboard.
For a deeper local-first architecture, read the local control smart home guide.
Bring AC, TV, Fans and Shades into the Same App
Many useful appliances are not new enough to have a modern app, but they still respond to an IR or RF remote. That is where LinknLink remote products extend the multi-brand story beyond cloud integrations.
| Need | Recommended path | App result | Local automation value |
|---|---|---|---|
| AC, TV, fan, or projector | eRemote HA | IR appliance commands can join room scenes. | Direct Wi-Fi + MQTT supports local Home Assistant control without a separate hub. |
| Presence plus IR in one room | eMotion Pro | Room presence and appliance control share one context. | Built-in IR reduces the number of devices needed for a room automation. |
| Precise 60GHz presence and climate context | eMotion Ultra | App scenes can use presence, built-in IR, and temperature/humidity data through its sensor cable. | Useful for comfort scenes that should not treat a quiet occupied room as empty. |
| RF shades, outlets, or remotes | eHome HA | RF actions can appear beside lights, climate, and other room scenes. | MQTT routing keeps repeatable RF actions available to Home Assistant. |
Use Agent+ to Reduce App Navigation
Once rooms and devices have clear names, Agent+ can help create scenes, build automations, personalize cards and layouts, connect devices, schedule routines, and diagnose problems through natural conversation. The useful difference is not voice for its own sake. It is the ability to describe an outcome without remembering which vendor menu contains the control.
| Request | What Agent+ should clarify | Safe result |
|---|---|---|
| Make the living room comfortable for movie time. | Which lights, AC or fan, curtains, and TV scene should be used? | Create a draft scene and ask for review before saving. |
| Why did the bedroom scene fail? | Which device was offline, which command failed, and whether manual control still works. | Present a diagnosis and preserve manual control. |
| Show the controls my family uses. | Which cards, rooms, scenes, and warnings should stay visible? | Simplify the layout without deleting underlying Home Assistant entities. |
A Practical Cross-Brand Room Example
Consider a living room with lights from one brand, curtains from another, an older IR-controlled AC, a television, and a LinknLink presence sensor. The useful automation is not five separate integrations. It is one room mode:
- Presence keeps the room active while someone is sitting still.
- The evening scene lowers the lights and closes the curtains.
- Local IR prepares the AC or fan without opening another app.
- The TV scene stays available on the same room card.
- Agent+ can adjust the scene after confirming the intended room and devices.
Use the LinknLink App automation guide for the next step.
Choose a Suitable Presence Layer for Each Room
| Product | Recommended fit | App and automation value |
|---|---|---|
| eMotion Air | Flexible, battery-powered placement where wiring is difficult. | Adds presence context without requiring a nearby outlet. |
| eMotion Pro | Rooms that need presence plus built-in IR. | Combines occupancy and appliance control in a compact room setup. |
| eMotion Ultra | Premium rooms needing 60GHz presence, built-in IR, and temperature/humidity context. | Supports more precise comfort and quiet-occupancy decisions. |

Multi-Brand Setup Checklist
- One home and room structure is agreed by the household.
- Devices use spoken, room-specific names.
- Each connected brand has been tested before the next one is added.
- Family-facing Home Assistant entities are exposed to the app.
- IR and RF appliances retain manual control.
- One cross-brand scene works before more complex automations are built.
- Agent+ requests identify the room and desired outcome.
- Remote access is limited to the controls that are actually needed.
FAQ
Can one app control supported smart home devices from different brands?
Yes. The LinknLink App is designed to bring supported devices from 2500+ brands into one room-based experience. Available controls depend on each device, protocol, and integration.
Does LinknLink replace Home Assistant?
No. Home Assistant can remain the local automation and entity layer, while the LinknLink App provides room cards, natural-language control, scenes, diagnostics, and family-friendly navigation.
