NO SMART HOME NEEDED?
Just need good heating control? You are in the right place.
Many people think a smart home is expensive and complicated. You do not have to want one: myIO is a universal controller. If that is all you need, it is a full-featured heating and cooling controller that you can freely expand later, as you like.
- It controls zone by zone, runs the pumps, the boiler and the heat pump, and watches the dew point.
- You do not have to use it as a smart home: your electrician installs it, and it quietly does its job.
- A full smart-home controller as a bonus: lighting, blinds, gates or solar, whenever you want, without a new system.
What can myIO do?
Six areas, one system. Each has its own page with all the details.
Heating and cooling
ZONE BY ZONE · MIAThe right temperature in every room, and the system learns when to start heating early.
Lighting
SCENES · DALIScenes, dimming, LED strips and presence detection in one system.
Shading and gates
BLINDS · GATEBlinds follow the sun and the clock, the gate follows your phone.
Energy and solar
USE SURPLUS LOCALLYYour solar surplus heats the boiler and the heat pump instead of going to the grid.
Security
ALARM · ALERTSWorks with your alarm panel and tells your phone when something is wrong.
Control
APP · VOICE · TABLETFrom your phone, a wall-mounted tablet or by voice, at home and away.
Which myIO is right for you?
Three controllers, one system. You get an itemized price in the Studio, calculated for your own home.
myIO Server V4 GIGABased on Arduino GIGA
Power for large homes, an upgrade for V3.
Everything the V3 does, plus:

How does it become a smart home?
You plan it
Draw your home in the Studio and get an itemized price. Free, no account needed.
Your electrician installs it
Standard DIN-rail cabinet and star wiring. No electrician yet? We recommend a myIO partner.
You use it
App, voice and automations. Updates bring new features without touching the wiring.
Why myIO?
Keeps improving
A gateway to new possibilities: new features arrive through updates, on your existing wiring.
Works without internet
Your home decides locally, so it keeps working without internet. The cloud is only a convenience.
Self-learning heating
MIA learns your home’s heat loss and thermal inertia and tunes the heating to match.
AI assistant
Talk to your home: an AI assistant answers, switches things and helps with the setup too.
Open API
It has a published programming interface, so other systems and your own programs can connect.
Growing integrations
No dead ends: Home Assistant, Homey, Matter, KNX, Modbus, MQTT, Shelly, and the list keeps growing.
No lock-in
Relays, push buttons, sensors, power supplies: standard parts you can buy anywhere and replace any time.
Built on proven ground
Based on Arduino, the open platform from Italy used by millions. The V4 Opta runs on Finder’s industrial PLC.
Encrypted connection
TLS encryption for remote access, and on V4 a hardware crypto chip that protects the keys.
10-year warranty
On every product myIO makes itself, main boards and expanders. Because you build a house for decades.
No mandatory monthly fee
The system is yours. Only the cloud and priority support are yearly services, and both are optional.
Developed in Hungary
Built by engineers in Hungary, who also answer your questions when you need help.
AI ASSISTANT
Talk to your home!
You can connect artificial intelligence to myIO. Ask, and it answers. Request, and it takes care of it.
Ask your home
How warm was the kids’ room last night? How much did the solar panels produce today?
Ask, and it is done
Switching, temperature, blinds: in writing or by voice, just as you would tell a person.
Helps with the setup
Explains the options and walks you through the setup.
Troubleshoots with you
If something does not work the way you want, it helps you find out why.
How does it work? MCP (Model Context Protocol) is an open standard that lets an AI assistant, such as Claude or ChatGPT, access your home: it sees the sensors and, if you allow it, switches things too.
