The room gets ready before you arrive.
The calendar shows a meeting at nine. The air conditioning came on a little earlier, the screen lit up and the curtain came down.
Comfort and automation
Systems That Act Together.
Lighting, climate, sound, curtains and sensors working together so the space adjusts itself. Comfort at home, efficiency at work and fewer things to remember.
In a few words
Automation is when one system reacts to another without anyone pressing a button: the room gets ready at meeting time, the light turns off when the last person leaves, the water shuts off when the sensor detects a leak. ARX designs, installs and maintains these rules in homes, stores, hotels and businesses.

In your day
You use it every day and almost never notice.
When automation is done right, it feels like the space can guess. The room is already ready, the light is already off, the water is already shut. Nobody pressed anything.
The empty room stops using energy.
The guest left for the day. The air conditioning turns off and the curtain closes until someone returns.
One touch and the house changes mood.
The dinner scene turns on the table light, dims the living room and starts the music. Nobody walks across the room to six switches.
The leak shuts off its own water.
The floor sensor detected water. The valve closed by itself and the owner received the alert on their phone.
When it fails
That's when everyone notices.
The three problems we find most often, where they come from and how we avoid them.
Automation works until the internet goes down.
Where it comes fromEverything was built with standalone devices that depend on the cloud and Wi-Fi. Without internet, not even the wall switch responds properly.
How ARX avoids itThe wall switch keeps working in any situation. We prefer rules that run on site, and each one is tested without internet and without power.
Only one person in the house knows how to use it.
Where it comes fromEach device has an app, each app has a password, and the scenes were created by whoever installed them, without asking anyone about their routine.
How ARX avoids itWe start with the routine of the people who use the space. A few scenes, with obvious names, on the switch and on the phone. If a visitor cannot turn on the light, it is wrong.
The light turns off with people in the room.
Where it comes fromThe rule was created without thinking about exceptions: the meeting that runs over, the Saturday cleaning, the sensor that cannot see someone sitting still.
How ARX avoids itEach rule is written with a trigger, a condition, an action and an exception, and tested with you. What does not pass the test does not go in.
How ARX does it
Simple for you. Rigorous on the inside.
We start with the routine
What the morning, the departure, the arrival, the meeting and the closing look like. Good automation repeats what people already do, only by itself.
You receive: the list of routines worth automating.
We write each rule
When this happens, under this condition, the system does that and notifies a given person. One line per rule, in plain language, before choosing any equipment.
You receive: the rules table, for your approval.
We install without removing the switch
Manual control remains alongside the automatic one. The devices stay on a separate network, and the accounts and passwords stay in your name.
You receive: the scenes on the switch and in the app.
We also test what goes wrong
Each rule is tested with internet, without internet and without power. After real use, we adjust schedules and scenes with you.
You receive: the test results and the agreed adjustments.
Equipment
What goes into your project.
Examples of what we install. The final choice depends on your space and your budget.
If the sensor detects a leak, the valve closes by itself and you are notified.
Connects intrusion, smoke and water sensors and alerts you through the app within seconds.
Arm, disarm and receive alerts from wherever you are.
Network, cameras, doors and alarm from the same family, managed in one place.
One screen to view and adjust the network, cameras and access, on a computer or phone.
Network, Wi-Fi and connection security. Cameras, recording and video intelligence. Doors, readers and intercoms.Brands
The right brand is the one that fits your project and your budget.
AjaxWhen automation starts from security: the sensor detects water, smoke or temperature and the system acts right away.
UbiquitiWhen network, cameras and doors are already from the same family and an event in one system needs to trigger another.
HikvisionWhen a single platform needs to connect video, doors, intercoms and alarms with if-this-then-that rules.
AxisWhen sound is part of the project: network-connected speakers for background music, scheduled announcements and zone paging.
IntelbrasWhen the idea is to start simple at home, with switches and sensors controlled by the app.
What hardly anyone tells you
Before asking for a quote, it's worth knowing.
Automation starts with the network, not the app.
Connected bulbs, sensors and speakers compete for the same Wi-Fi at home or at the office. With a weak network, the scene is delayed or fails. That is why we look at the network before talking about automation.
Standalone devices are easy to buy and hard to maintain.
Each brand brings its own app and its own cloud account. If the manufacturer discontinues the line, the function may disappear. Before buying, ask what keeps working without internet and in whose name the account is.
The test that matters is the failure test.
Any demo works with everything on. The useful question is a different one: what happens without power, without internet or with a broken sensor? Does the door open? Does the water shut off? Ask to see that test.
Questions and answers
Does automation work without internet?
The essentials should work. The wall switch still works, and rules that run on site stay active. Without internet, what is lost is remote control and some of the alerts. In the project, we separate what depends on the internet from what does not.
Do I need to renovate to automate?
Not always. There are wireless devices and modules that go behind the existing switch. In construction or renovation, it is worth leaving the conduit ready, because it widens the options. We assess what the space allows before proposing anything.
Can I automate just one part and grow later?
Yes, and it is usually the most sensible path. Start with what bothers you most: the living room lighting, the meeting room air conditioning, the risk of a leak. If the foundation is well chosen, the rest comes in later without redoing what was already done.
Does automation help save energy?
It helps avoid waste. Lights and air conditioning turn off by schedule or when no one is there, and no longer stay on overnight and on weekends. How much this amounts to depends on the space and its use. We do not promise a percentage.
Does the leak sensor shut off the water by itself?
Yes, when the project includes the valve. The sensor sits on the floor, near where water would appear first. When it detects water, the system closes the valve and alerts you in the app. It works for homes, laundromats, kitchenettes and equipment rooms.
Does ARX install automation in any city?
Installation, with an on-site team, is done in the State of São Paulo: the capital, the interior and the coast. Design, consulting and retrofit design, on the other hand, serve all of Brazil.
