FOR PROFESSIONALS

For professionals

For electricians, heating installers, designers, integrators and resellers: what myIO gives you for your work, and how we can work together.

myIO is a universal controller developed in Hungary. If your client needs nothing more, it is a complete heating and cooling controller that they can freely extend later with lighting, shading, energy and security. We develop the controller, the expanders and the software; the installation is done by professionals. Here we have gathered what you need for the job.

  • It mounts on DIN rail and is wired with the usual parts: push buttons, relays, terminal blocks, power supplies.
  • No programming: the setup wizard in the web interface guides you. (If you do want to program it, myIO Script is coming soon to V4.)
  • The wiring does not tie you to a manufacturer: the control can be replaced with conventional impulse relays at any time.
  • No mandatory monthly fee.
  • You talk to us directly, not to a call centre.

For electricians

With myIO, the wires of the push buttons, the sensors and the controlled loads run to the central cabinet: this is star wiring. Any NO/NC contact can be connected to the inputs, and the outputs are relays in the cabinet. Shielded FTP cable is recommended for the push buttons; the thermometers connect on a data bus, also over FTP, and fit in the push button’s wall box. The controller and the expanders mount on DIN rail, and the service display helps with commissioning and shows the controller’s IP address.

For your first job we give you a free crash course: in person, or online after you have gone through the documentation. If needed, you can order the control cabinet pre-assembled, and we can also come to the building site to direct and check the cabling.

For heating and plumbing installers

myIO controls heating and cooling zone by zone. The zone valve, the pump, the actuator and the start signal of the boiler or heat pump each go on a relay; it controls a mixing valve with a 0–10 V signal, couples the pump to the circuits, and can also switch the heat pump with an SG-Ready signal. For ceiling and wall cooling, the myIO DewPoint provides dew point protection, and the heating and cooling lockout protects the floor from overheating.

myIO also speaks Modbus RTU. Through the Modbus Bridge beta, data from heat pumps, inverters and other Modbus devices can come into myIO, and as a sensor it can control an output too. It is in beta testing on the V4 Opta and coming soon to the V4 GIGA. So far we have tested it with an Eastron SDM630 energy meter: if you would like to connect a particular heat pump, tell us which one.

For designers

In the myIO Studio you draw the house and what your client would like, and you get an itemized device list, together with the design of the control cabinet. It is free, and no account is needed. You can also send us the finished design from there to ask for a quote.

The differences between the three controllers are shown in the detailed comparison on the Which myIO is right for me? page, and the descriptions and wiring of the boards are in Downloads.

For integrators

If a premium system is too expensive for your client, don’t lose the job: offer them myIO. The wiring is done the same way, in a cabinet with star wiring, and myIO is open to other systems:

  • Home Assistant: connects over MQTT, the devices appear on their own.
  • Homey: with an official myIO app.
  • Matter connection (beta): myIO devices in the Google Home, Amazon Alexa and Home Assistant apps too.
  • Bridges (beta): KNX, DALI, DMX and Modbus RTU.
  • Open API (a published programming interface) over HTTP, and MQTT for any other system.
  • AI assistant (myIO MCP): Claude or ChatGPT reads, switches and configures myIO.

For resellers

You can sell myIO on reseller terms. We agree on the discount, the price list and the details of working together in person: apply through the Partner program, or write to us.

Partner program

We have two partner levels for professionals. The Registered myIO Partner starts when you apply: a partner discount, a free crash course and a direct contact person. After the crash course and the first finished project, the Certified myIO Partner gets a larger discount, we pass on the enquiries from their region, and they are added to the partner list on our website. Anyone with their own audience can become a myIO Referrer, with their own referral code.
