myIO Server V3
Looking for good heating control rather than a smart home? The V3 does far more than you would expect from a heating controller, and it is a full smart-home controller as a bonus, with unbeatable value for money.
You get an itemized price in the Studio, calculated for your own home.
Who is it for?
- You are building or renovating, and you want good heating and cooling control, not a smart home. You get a full smart-home controller as a bonus.
- Think a smart home is expensive and complicated? You do not have to use the V3 as one: your electrician installs it, and it quietly does its job.
- Besides stability and comfort, cost matters to you too.
What you get
Heating and cooling by zone
Every zone heats or cools by its own temperature sensor, on a weekly schedule. Dew-point protection stops cooling before condensation forms on cold surfaces.
Switches a lot
32 outputs and 16 inputs out of the box: relays, valves, dimmable lighting, push buttons, sensors. With expanders, up to 160 outputs and 128 inputs.
Temperature and humidity
Up to 40 temperature sensors and 8 humidity sensors, so every room is measured separately.
Solar and heat pump
The Energy Manager uses your solar surplus inside the house, and the SG-Ready signal tells the heat pump when heating more is worth it.
App, voice, AI assistant
Besides the myIO App and the web interface: voice control in Hungarian on Android, and an AI assistant you can talk to about your home.
Works with others
It works with Home Assistant and Homey, and controls Broadlink devices and the Computherm Wi-Fi thermostat.
- 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
A heating controller, with a smart home as a bonus
Many people think a smart home is expensive and complicated, so they never start. Yet almost every home needs good heating control. 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. The same controller switches relays and reads push buttons and sensors, so lighting, blinds, gates or solar panels can be connected too, whenever you like.
You do not have to decide in advance, and you do not need a new system. If all you want is heating, that is what you get, but the option is there in the cabinet.
How far it takes you, and how to move on
The V3 is a mature, proven controller, but it is reaching its limits: there is no room left in it for new features. It still gets security and minor updates, while new features go to V4.
Not available on V3:
- myIO Cloud (secure remote access)
- myIO Link (connecting several controllers)
- Shelly devices
- MIA self-learning heating
- KNX, DALI, DMX and Modbus bridges
- Flow (rules without code) and myIO Script: these also come to V4
Easy to upgrade later: if you want more, your electrician swaps the processor board on the main board, and it becomes a V4 GIGA. The wiring, the cabinet and the SD card all stay.
