My smart home has five apps. Can it be one?
Lights in one app, music in another, cameras, thermostat and TV in their own. What can be joined, what stays where it is, and the order to do it in.
The short answer. Yes, for daily use. A control platform such as Control4 sits above the separate systems, connects to each one, and gives you one interface on phones, touchscreens and keypads. A standard called Matter helps devices from different makers talk to each other underneath. Some apps will still exist for deep settings, and that is fine. IntegrateIT, in Overland Park, plans this for houses on both sides of the Kansas City state line, and we start by listing what you already own.
The quick version of this question, one app for lights, shades, TV and cameras, is answered in a few lines on our smart home automation page. This article is for a house that is already built and already crowded: five or six apps on the phone, each from a different maker, none aware of the others.
Why the apps pile up
Nobody decides to own five apps. A house collects products over years. The lights came with the builder, the cameras came from a hardware store, the thermostat arrived with a rebate, and the music system was a gift. Each maker ships an app for its own product, and each app is competent at its own job. The trouble is the gaps between them: turning the house into a movie mode means opening three apps, and a guest cannot use any of it. We wrote about how that usually plays out in DIY versus professional installation.
What can merge
Two different things can join separate systems, and they work at different layers.
A control platform
Control4 describes bringing a large catalog of devices into one platform, run through one interface on phones, touchscreens and on-wall keypads, and says it works with thousands of Control4 and third-party products. In practice the platform is where scenes live: one press that dims the lights, lowers the screen and starts the system. We are a Control4 Platinum Dealer with a Control4 Certified Showroom, and we also work with Lutron: we are a Lutron Certified Dealer, HomeWorks Certified and Ketra Certified. Lutron describes its controls as covering lighting, window treatments and the integrated smart home,.
A standard between devices
Matter comes from the Connectivity Standards Alliance. It is built so devices from different brands set up and work together, and it supports more than thirty device types, among them lighting, climate, cameras and doorbells, and security devices. A Matter device can be added to more than one ecosystem, and the Alliance lists Apple Home, Google Home, Amazon Alexa and Home Assistant among the places it is deployed. That is real progress, but it is a layer for devices. It does not write your scenes or decide what a keypad button does. For where it meets Control4 specifically, see our note on Control4 with Apple Home and Home Assistant. We state no Matter feature for any one platform, so ask what your own controller does today.
A voice and touch layer
Josh.ai describes a single interface by touch, text or natural voice, covering lights, music, TVs, thermostats and cameras across the home. It is a layer you speak to, and it is only as complete as the connections behind it. We are a Josh.ai dealer, and the showroom has it running.
What stays in its own app
Joining systems does not delete the maker apps. Some jobs belong in them: setting a camera’s motion zones, updating firmware, changing a rarely touched schedule, pairing a new device. The goal is for the daily actions to live in one place, and for the maker apps to become the toolbox you open twice a year.
| What it does | Daily use | Maker app is for |
|---|---|---|
| Lights and shades | One interface, scenes, keypads | Programming and diagnostics, by the installer |
| Music | Pick a room and a source in the one interface | The music account and service sign-ins |
| Cameras | Live view and a doorbell alert | Zones, retention and firmware |
| Thermostat | Temperature and modes in the room scene | Schedule setup, reminders |
| TV | Power, source and volume from the touch panel or keypad | Streaming app logins |
What to leave alone
The honest part of this job is the list of things we do not touch. A thermostat that holds its schedule and nobody complains about can stay as it is until the platform can read it. A music system that everyone in the family already loves can stay a music system. The only things that must change are the ones that do not connect, keep dropping off the network, or are in a lineup the platform cannot reach. A takeover is a survey before it is a shopping list, which is why we start with the system takeover walk-through, and why the order of repair in what we fix first in a smart home that never worked begins with the network and not the apps.
The order we do it in
- List everything. Open every app on every phone in the house. Write down what each one controls, what it connects through, and who uses it. This is the map.
- Check the network. Controllers, cameras and streamers all rely on it, and a platform inherits its weak spots. Dropped connections get fixed before anything is joined.
- Choose the control layer. One platform, chosen for the house and the people in it, not the other way round.
- Connect what connects cleanly. Lighting, shades, audio, video, thermostats and cameras that the platform can reach go in first, room by room.
- Replace what cannot be reached. The few devices that will not join, or cannot be trusted, are swapped for ones that do.
- Write the scenes and add the keypads. Arrive, movie, goodnight. The point of all this is the one press.
- Add voice last. A voice layer is the cherry on a system that already behaves, not a way to hide one that does not.
Do it room by room, not house by house. The family room is usually first because it holds the TV, the lights and the music, and by the time it works, the household already prefers the new way.
When a mixed house should not be merged
Sometimes the right answer is less than one app. If two systems never need to talk, such as a standalone alarm that already does its job, joining them adds a failure point and no benefit. We say so on the walk. The aim is a house that behaves, not a house that has been joined for its own sake.

Questions
Questions we hear
Why does my smart home need so many apps?
Because each maker ships an app for its own product, and a house usually collects products one at a time. Lights from one company, cameras from another, a thermostat, a streamer, a speaker brand. Each app is fine alone. Nothing joins them until a platform or a standard does.
Will Matter put all my apps into one?
Matter helps devices from different makers work together, and one Matter device can be added to more than one platform. It does not turn five apps into one screen by itself, and it does not do your scenes, keypads or room logic. It is useful plumbing underneath a control layer, not the control layer.
Do I have to replace everything I already own to get to one app?
Usually not. We start by listing what you have and sorting it into what can join a platform, what is better left in its own app, and what is failing. Many working devices stay. The things that get replaced are the ones that cannot be reached or keep dropping off.
Which apps should I keep even after everything is joined?
The ones you use for setup and diagnosis: the camera maker’s app for settings, the thermostat app for a schedule you rarely change. Daily use moves to one place, and the maker apps stay installed for the occasional deep setting.
Can one voice assistant or one app really cover music, TV and thermostat together?
It can when each of those is connected to the same control system underneath. Voice and touch layers such as Josh.ai talk to the systems already in the house, so they are only as complete as the connections behind them. We check each connection before promising the result.
What does the first visit look like if my house is already a mix of everything?
We walk through with you, open every app you use, and write down what each one controls and how it connects. You get a short plan in order: network first, then the control layer, then the rooms. Call or text (913) 804-7575 or book a no-cost assessment at integrateit.tech/book/.
