Smart Home Installation
Budapest & Danube Bend
Automation from Esztergom to Budapest!
My goal is to design and install comfortable, safe, and highly energy-efficient smart homes without unnecessary wall demolition or dusty, messy construction.
Forget buggy remote clouds and monthly recurring subscription fees. My bespoke systems run lightning-fast and are 100% locally-managed, working even during internet outages.
Comfortable Life Situations
I don't just sell you hardware modules; I build a stress-free, secure, and energy-preserving lifestyle. Click on any of the common card setups below to view exactly how I solve each challenge in your home.
See who is at the door directly on my phone
Get live video and talk to courier drivers or welcome family members on your phone from anywhere in the world.
Get alerted on my phone if there's a water leak
Autonomous damp pads shut down the main home water valve instantly in case of laundry pipe breaks, preventing massive structural damage.
Automatic soft pathway lighting at night
Presence sensors illuminate hallways with rich, golden, glare-free dim lighting at 8% during late hours, preserving your sleep state.
View and control current room temperature remotely
Set fine-tuned target temps per room. Lower empty room radiators while you are away, reducing home heating bills by 15-30% automatically.
Forgot to unplug the iron? Cut power from anywhere
Shut off hazardous appliances remotely or set protective timers that auto-kill power if devices draw heavy wattage for long periods.
Get notified as soon as my child arrives home
Front door magnetic context toggles send reassuring push reminders to work phones during after-school hours.
Private, Local-First Infrastructure
My systems are engineered around absolute data privacy and offline operational safety. I do not rely on remote servers located in foreign cloud grids. Everything stays inside your home.
Automated Synergy
Rather than jumping between dozens of mismatched, sluggish individual apps, all your lights, locks, heating zones, and sensors operate as a single unified ecosystem.
100% Data Privacy
The central controller acts as a small physical computer server tucked away in your home. Your cameras, credentials, and records never leave your physical walls.
Offline Independence
The localized smart micro-network handles triggers and sensor inputs directly. If your internet service goes down, your smart home schedules function perfectly with zero lag.
How Will You Control It?
Mobile Application
Control everything from a single sleek, personalized client panel (Home Assistant companion app) across all iOS, Android, and tablet units.
Custom Private URL
Securely access your home from anywhere via a personalized sub-domain (e.g., yourname.helyiokos.com) utilizing fully encrypted SSL protocols.
Vocal Control
100% cloud-neutral or compatible with your choice of Google Assistant or Amazon Alexa voice controllers for easy hands-free commands.

How is my pricing structured?
No hidden costs, recurring software licensing fees, or surprise monthly subscriptions. Your custom localized smart home consists of two transparent items:
1. Local Central Server & Coordination
The brain of your smart home. Includes your secure physical mini-computer local server, strong network antenna arrays, custom software logic definitions, tailored companion UI layouts, secure external SSL routing, and my complete face-to-face on-site analysis.
2. Tailored Smart Modules of Choice
Pay only for the features you truly want. From automatic smart radiator sashes and motor shades to biometric door handles, my responsive calculator adjusts counts matching your real property size, including clean physically-fitted mounting support!
Compatible Smart Devices & Modules
On top of the local central server hub, the following high-grade wireless devices and modules integrate seamlessly into your home. This list covers procurement, offline pairing, and automation logic.
Battery-Powered & Low Voltage Modules (mess-free, requires zero wall drilling or electrician callouts)
⚠️ High-Voltage (230V) Smart Modules ❗ Physical wiring must be prepared by a licensed electrician!
💡 Seamless Pricing Details: All prices are inclusive of high-durability module sourcing, calibration, offline server sync, and dynamic routine programming. Physical mounting of 230V components in-wall must be performed by your electrician of choice, for whom I supply accurate wiring templates and telephone support entirely for free.
⚠️ 230V Mains / Electrician Cooperation Rules
HelyiOkos prioritizes safety above all else. While the bulk of our sensors and switches operate off harmless low-volt button batteries (incorporating no dust, drills, or cables), in-wall relays, floor thermostats, and heavy garage openers run on standard 230V high-voltage lines.
❗ For your safety and warranty verification, 230V mains high-voltage electrical mounts must only be conducted by a licensed, certified electrician.
What your electrician does:
Physically fits süllyesztett (in-wall) modules behind switches, wires 230V cables on boiler terminals, and hooks mains power to smart assets.
What HelyiOkos does:
I construct complete schematic diagrams and assist your contractor. Once hooked up, I carry out the entire software config, offline central key pairings, and custom routines.
