myIO Server V3 is a mature, proven controller, and it stays that way. But it has reached its limits: there is no room left in it for new features. That is why we made V4: a new generation of controller that can handle far more at once, and that the new features of the coming years arrive on.
What does V4 bring?
- Much more power. A dual-core, several times faster processor and many times more memory: it handles many phones, tablets, automations and logs at once.
- Access from anywhere. Through myIO Cloud you reach your home from your phone from anywhere, without port forwarding or router settings. The first year is free.
- Encrypted connection. The remote connection is encrypted, and the keys are protected by a separate security chip.
- WiFi too. It can connect to the network by cable or over WiFi.
- Several controllers together. With myIO Link several controllers can be connected, for example in a larger house, or between the house and an outbuilding.
- Everything the V3 does. Zone-by-zone heating and cooling, Energy Manager, SG-Ready, app, voice control, AI assistant, Home Assistant and Homey.
And what is coming soon, through updates, without touching the wiring:
- Flow: rules without code, for example “if the window opens, stop the heating in that room”.
- myIO Script: programmable logic for complex tasks, for advanced users and professionals.
- MIA, self-learning heating: it learns how your home holds heat, and adjusts the heating to it. We show what this means in practice, with measurements.
- Shelly devices: we are testing them now.
Two versions
V4 comes in two versions. The same software runs on both; the difference is in the hardware and in how far they expand.
V4 GIGA: the most modern myIO
The V4 GIGA is built on the same main board of our own make as the V3, just with a more powerful processor board. If the V3 is not enough, or you simply want the latest, choose this one. Available now.
If you already have a V3, you do not need a new system: your electrician replaces the processor board on the main board, and it becomes a V4 GIGA. The wiring, the cabinet and the SD card holding your settings all stay. The V3’s expanders work on it too, and the myIO Expander 16 and the bridges (KNX, DALI, DMX, Modbus) are coming to it soon.
V4 Opta: certified industrial hardware
The V4 Opta is built on Finder’s Opta industrial controller (PLC): a certified device designed for industrial environments (CE, cULus, ENEC), taking up just 4 modules on the DIN rail. Up to 10 myIO Expander 16 units can be connected to it with a single bus cable, for a total of 160 inputs and 160 outputs. If the connection is lost, the expander keeps working with its own settings, so the heating, for example, does not stop.
With bridges, KNX devices, DALI and DMX lighting and Modbus devices become part of the system too; these are in beta now. The V4 Opta is coming soon: subscribe on its product page, and we will let you know.
Which one is for whom?
- V3: if you are looking for a good heating controller and cost-effectiveness matters most. As a bonus, it is a complete smart home controller too.
- V4 GIGA: if you want the most modern, remote access through myIO Cloud, or you would move up from the V3 with your existing wiring.
- V4 Opta: if you want certified industrial hardware in the cabinet and you are building a large system, even with KNX, DALI, DMX or Modbus devices.
You can compare the three controllers item by item on the Which myIO is right for me? page. What your home needs, and what it costs, you can plan in the myIO Studio.
From V3 to V4 GIGA in four steps
- Save the sensors: in the V3’s web interface, you export the list of sensors.
- Replace the processor board: your electrician replaces the processor board on the main board.
- Load back what you saved: on the V4 GIGA you import the sensors and add the users again.
- Update the SD card: you update its content online, and you are done.
For professionals
- V4 GIGA: Arduino GIGA R1 on the main board (in place of the Arduino Due); dual-core, 480 + 240 MHz; 1 MB + 8 MB RAM; Ethernet + WiFi; SD card + internal flash; hardware crypto chip; 12 DIN modules, like the V3.
- V4 Opta: Finder Opta WiFi industrial PLC (8A.04.9.024.8320); dual-core, 480 + 240 MHz; 1 MB RAM; 12–24 V DC; 4 DIN modules. Built in: 4 relays (1 of them the Ready relay) and 8 analogue inputs (0–10 V only); wall switches go on the Expander 16. Up to 10 Expander 16 units on the RS485 bus.
- Remote access: myIO Cloud with TLS encryption; the keys are protected by a hardware crypto chip.
- Bridges on RS485 (KNX, DALI, DMX, Modbus RTU): V4 Opta beta, V4 GIGA coming soon.
- Remote software updates over the network; the new firmware can also be requested by email, and owners can upload it themselves.
