Smart home design and installation in Budapest

Comfortable, efficient and secure: what a modern smart home looks like

Just as a TV isn’t smart simply because it has a remote control, a home doesn’t become a smart home just because you can control the air conditioning from your phone or the shutters with a remote. Remote control is an important capability, but you can only really talk about a smart home when these systems adapt to their surroundings and to the habits of the people living there – improving comfort, security and quality of life without anyone having to step in, and even reducing your ecological footprint by using energy optimally.

That said, home automation isn’t about everything always happening on its own. A good system takes repetitive chores off your hands, alerts you in good time, stays controllable by hand and gives a clear message if something goes wrong.

MindzenSmart designs and installs wired and wireless smart home systems. We design for local control: automations keep running without the internet, and your data doesn’t depend on a cloud provider based abroad. Because we also hold a security systems installer licence (the Hungarian official licence for installing security systems), we can integrate security functions alongside the comfort features.

A day in the smart home

The same house in the morning, while you’re away, in the evening and at night – the system switches by itself, so you don’t have to change any settings.

What problems does it solve?

A well-designed smart home can help with:

Room-by-room heating and cooling control, based on how rooms are used and on the weather
Controlling shutters, other shading and lighting to suit the time of day
Making energy consumption visible and optimising it
Managing the times you're away – presence simulation, everything off at the touch of a button
Early warning of water leaks and other technical faults, with automatic shut-off
Monitoring presence and movement without cameras
Making better use of the energy your solar panels produce
Replacing lots of different manufacturer apps with a single interface
Linking the alarm system with comfort functions, so the same sensors serve more than one purpose

What's worth knowing up front, though: a smart home brings comfort and measurable savings, but it isn't magic. It won't make a poorly insulated house cheaper to heat, and the system is only worth as much as you actually use it. That's why we'd rather recommend fewer automations that work well than lots of them that everyone switches off after two weeks. A good smart home system can be expanded later.

Who is this service for?

People renovating or building new who want to lay the right foundations for the system as early as the electrical installation – shutters, heating, lighting and shading from a single hub
Apartment owners who can’t chase into the walls: we work without opening walls, using wireless devices – Zigbee, Z-Wave, Thread, Wi-Fi – and modules fitted behind your existing switches
Those who have already made a start: we bring mixed-brand, half-finished systems – Shelly here, Philips Hue there, separate apps for each – under a single hub
Companies and offices, where controlling heating, lighting and shading delivers measurable energy savings – the version tailored to commercial buildings is building automation and building management

Where should control run: locally, in the cloud or a mix of both?

This is the decision that's most expensive to change later, so we start the site survey with it.

Local control

The control logic runs on a hub in your home. Switches, shutters and heating keep working even if the internet goes down or the manufacturer's server stops, and presence data doesn't travel to an outside provider. In return, you need a hub in the house, and setting it up takes more expertise than an out-of-the-box device paired with an app.

Cloud control

Each manufacturer's own apps and servers do the work. It's quick to get going, cheap to start with and instantly accessible remotely. In return, you have several apps to manage, how well the devices work together depends on manufacturer support, and the service may stop working without the internet; some features may also come with a subscription over time. It's also worth considering where the provider's infrastructure runs and how transparent its data handling is.

Hybrid set-up

In practice, this is the most common: the functions essential to running the house – heating, shutters, lighting, water shut-off – run locally, while convenience extras can stay in their own ecosystems, all integrated into a single interface.

What decides it? What should happen when the internet goes down, how much it bothers you if your data ends up on an external server, how big the system is – a few points or an entire house – and what starting budget you have in mind. If the site survey doesn't settle it, we'll quote for several options so you can compare them.

What do we survey?

A site survey isn't just reading out a list of devices. On site, we go through the following:

The list of rooms and your daily routine: what should happen automatically
The existing electrical installation, the size of the back boxes, and whether there's a neutral wire at the switches
The type of shutters and blinds, their motors and how they're currently controlled
The type of heating system: radiators, underfloor heating, and whether the boiler or heat pump can be controlled
The smart devices and apps you already have – which of them can be integrated
Internet connection, router location, Wi-Fi coverage and whether the network can be segmented
Radio environment: channel occupancy in the 2.4 GHz band, background noise in the 433 and 868 MHz bands
The physical location and power supply of the future hub and network equipment
Where the water supply enters the building and whether it can be shut off
Existing alarm, cameras, intercom and gate opener, if there are any
Who will use the system – children, elderly family members, tenants, cleaners – and through what interface
The pace of expansion: what's worth starting with and what can come later

What can the service include?

Needs assessment and system design: room list, a function matrix – what to control and based on what – choice of platform and protocols, and device allocation. The design document remains useful even if the installation is scheduled in several stages
Radio network and frequency coordination: on-site measurement, then channel allocation in the 2.4 GHz band (Wi-Fi, Zigbee, Thread). For 433 and 868 MHz devices (alarm sensors, Z-Wave, gate openers), we choose where the hub and repeaters go and filter out sources of interference, so the devices don't disrupt each other or put unnecessary load on the neighbours' networks
Hub and network: installing the chosen hub, building the radio networks with planned coverage, and separating smart devices onto their own Wi-Fi network or VLAN. That way they can't see your personal devices, and a vulnerable light bulb can't open a door into your home network
Device installation: relay and shutter modules, either built in or hidden behind switches, thermostats and radiator valves, smart locks, LED control, sensors and special-purpose hardware
Programming automations: away mode, presence simulation, room-by-room heating and cooling schedules, dusk-controlled shading, automatic shut-off in case of a water leak, and anything else the particular site needs
Training and handover documentation: technical design, device list, network description and automation register
Optional follow-on: smart home aftercare, later fine-tuning and firmware updates

Which brands do we work with – and why?

We don't force a single ecosystem onto every site. We choose the hub, the protocols and the devices based on the function you want, your existing system, local operation, expandability and long-term support.

Scroll sideways to see the brands in each category

Homey Pro handles Zigbee, Z-Wave, Matter/Thread, Wi-Fi, Bluetooth, 433 MHz and infrared devices in a single unit, and automations run locally – so basic operation can continue during an internet outage. Devices from different manufacturers can be linked in one interface and in shared workflows.

A system built with a building-services mindset that brings wired and wireless components together for joint control of lighting, shading, heating and cooling, and energy monitoring, with a local hub and a single app.

Offers simple, consistent control for Apple-centred households; a suitable Apple TV or HomePod acts as the home hub, running automations and providing remote access, and it also supports adding Matter/Thread devices.

A Z-Wave-centred platform for locally running automations and more complex scenes, and a particularly good choice for systems built with Fibaro modules and Nice gate and shading equipment.

SATEL's Smart&Safe system: built on ABAX 2 wireless technology, it combines security and home automation in a single hub. It's at its strongest where the alarm and the smart home aren't two separate systems: the same sensors serve both protection and comfort functions, and control runs locally.

This list isn't exhaustive – we work with other brands too. We also use products from manufacturers that make only one or two devices, when those are the best solution for a specific need.

Everyday operation

Useful automations in practice

Leaving routine

With a single action, the system can check for a door or window left open, switch off certain appliances, set the heating to the right mode and get the alarm ready. You get clear feedback on what has happened and what is still pending.

Arrival routine

After an identified entry, the hallway lights can come on and comfort mode can be restored. Security functions, however, can only be released by a verified event with the right permissions.

Opening and closing a shop

In a single summary view, the operator can see whether the premises have been locked up, whether the alarm is armed, whether any critical appliance has been left on or any door left open, and whether the monitored temperatures are in order.

Abnormal conditions

In the event of a water leak, excessive temperature, a persistent deviation in consumption or a communication fault, the notification can go to the person responsible. Automatic intervention is only justified when the technical and operational conditions for it are safe.

Night-time comfort and security

At bedtime the system can switch off unnecessary lighting, turn down the heating in the living areas, partly arm the alarm and, when it detects movement, switch on only subdued path lighting.

Solar power and EV charging

The system can adjust the operation of large loads – such as the water heater or the EV charger – to the current solar surplus and the building's load, so consumption doesn't exceed the available power.

Safe integration

Your security system shouldn't be a comfort experiment

The basic operation of the alarm, access control or any other critical function shouldn't depend needlessly on a general automation hub or a single cloud connection.

That's why, when integrating, we look separately at:

What works independently
What happens during an internet outage
What happens when the hub restarts
Which actions need separate confirmation
How the system signals that an automation didn't run
Who can change the rules

What makes up the price?

The number and condition of the systems to be connected
The sensors and controllers needed
The number of custom logic rules
The state of the local network and remote access
Manufacturer or third-party licences
Data logging and notification requirements
How thorough the testing, documentation and training need to be
Future modification and maintenance needs

That's why we always give a proposal and a quote tailored to your specific case.

Frequently asked questions

Can my existing smart devices be integrated?

In the vast majority of cases, yes. At the site survey we go through, item by item, which smart devices are already in the property. We take them into account when choosing the platform and tell you what can and can’t be integrated.

Does it need the internet?

Some of the basic functions can also work locally, but remote access, certain voice control features and manufacturer services may need the internet. We clarify this function by function.

Will I keep manual switches and controls?

Wherever possible, yes. Without a specific reason, we don’t make everyday basic functions controllable only from a phone.

What is a “scene”?

A saved setting that adjusts several devices at once – at the press of a button, at a set time or when something happens. A “Movie night” scene, for example, dims the lights and lowers the blinds. “Leaving home” switches off the lights, sets the heating to economy and arms the alarm. Smart home apps use the same name.

Can it be expanded later?

Usually yes, because we design it from the start with spare capacity in the system. It’s worth recording any future expansion plans as early as the first phase.

How much does it cost to install a smart home?

We can give an itemised price after the site survey, based on your specific needs, because a great many factors affect the cost of the complete installation.

Do the walls need to be opened up?

Not necessarily. Several manufacturers make compact in-wall relays, small switches and controllers that fit into the back box behind your existing switches, and the data connection is wireless. There are also wired smart home systems that use a bus, as well as hybrid systems combining wired and wireless solutions. We recommend a fully wired system for new builds or for renovations involving complete rewiring, where running the necessary cabling isn’t a problem.

Zigbee, Z-Wave, Matter, Wi-Fi – which is the right one?

Each has its place. Z-Wave is an open standard, but every device must be certified; in Europe it uses the 868 MHz band, which is less congested, so you can usually build a very reliable wireless system on it. Zigbee works in the 2.4 GHz band, is affordable and has a very wide range of devices. Matter provides a common language between ecosystems and can run over Wi-Fi or over a Thread network, which also operates in the 2.4 GHz band, but its range of devices is still narrower. Homey Pro, which we often recommend, handles all of them, so you don’t have to commit to a single protocol for good. Apple Home handles Matter devices natively; TapHome, besides its own wired components, can connect to Zigbee, Modbus and IP-based devices, among others; and the Yubii Home and Fibaro Home Center hubs are designed primarily for Z-Wave devices.

What happens if something breaks after handover?

We guarantee our work, and the devices are covered by the manufacturer’s warranty.
