myIO Server V4 GIGA
The most modern myIO: for when the V3 is not enough, or you simply want the latest. More powerful, built for heavier loads, and the upgrade path for V3 owners, on the existing wiring.
You get an itemized price in the Studio, calculated for your own home.

Who is it for?
- When the V3 is not enough: bigger needs, a more complex system, a lot running at once (several phones and tablets, integrations, automations), and you want a controller that takes a heavier load.
- When you want the most modern smart home, with the latest technology.
- You already have a V3 and want more: remote access, Wi-Fi and the new features, on your existing wiring.
What you get
Everything the V3 does
Heating and cooling by zone, Energy Manager, app, voice control, AI assistant, Home Assistant and Homey.
Handles the load
A dual-core, several times faster processor and many times more memory: it copes with many connections, automations and logs at once.
Access from anywhere
It connects by cable or Wi-Fi, and through myIO Cloud you reach it from your phone anywhere, without port forwarding or router settings.
Encrypted connection
Remote connections are encrypted, and a separate security chip protects the keys.
Upgrade from V3
If you already have a V3, the wiring, the cabinet and the SD card stay: only the processor board is swapped.
Expandable soon
myIO expanders and bridges are coming, and with them KNX, DALI, DMX and Modbus.
- 10-year warranty on the main board we make
- Remote software updates: you can also get the new version by email and upload it yourself
Available now, and coming soon
Features open up step by step, through updates. Nobody needs to touch the wiring.
- myIO CloudSecure remote access from your phone, without port forwarding or router settings.
- myIO LinkConnects several myIO controllers into one system, for example a house and an outbuilding.
- MQTT, Home AssistantStandard messaging: Home Assistant discovers the myIO devices automatically.
- Shelly devicesBrings Shelly Wi-Fi relays, switches and meters into myIO.
- FlowRules without code: if this happens, do that. For example: if the window is open, stop heating that room.
- myIO ScriptProgrammable logic for complex tasks, for advanced users and professionals.
- MIA self-learning heatingmyIO Intelligent Assistant: continuously learns the heat loss and thermal inertia of the house and tunes the heating parameters accordingly.
From V3 to V4 GIGA in four steps
Save your sensors
Export the sensor list in the V3 web interface.
Swap the processor board
Your electrician replaces the processor board on the main board. The wiring, the cabinet and the SD card that holds your settings stay.
Load what you saved
Import the sensors on the V4 GIGA and add the users again.
Update the SD card
Update the contents of the SD card online, and you are done.

More details
- Upgrading from V3
- On the main board the Arduino Due is replaced by an Arduino GIGA R1; the wiring, the cabinet and the SD card (parameters) stay. Sensors: export on V3, import on V4; users must be added again; the SD contents are updated online.
- Expanders and bridges
- Coming soon, through the serial port of the DMX/Modbus board (firmware in progress).
- Remote access
- myIO Cloud with TLS encryption, with a hardware crypto chip protecting the keys.
- Software updates
- Remotely, over the network; the new firmware can also be requested by email and uploaded by the owner.
