iAwards 2026 QLD Winner

Controls for every HVAC unit. Every major brand. One gateway.

Controls for
every HVAC unit.
Every major brand.
One gateway.

AirNexus builds controls for the HVAC you already have. The Nexus gateway connects to your air conditioning, hydronic or geothermal system, whatever the brand, and puts every unit under one set of controls: temperatures, modes and schedules, plus live faults and energy use in the Nexus iQ dashboard and the AirNexus app. For building owners and facility managers.

How it works

Plugs in. Reads everything. Reports to you.

The Nexus gateway sits beside your system

It connects to the control network your air conditioning already uses, any brand. About the size of a small router.

It reads every unit on the network

Daikin, Mitsubishi Electric, Samsung, LG and eleven more brands. Up to 32 indoor units on one gateway.

You watch and control it from Nexus iQ or the app

Temperatures, set points, faults, health scores and energy use, live. Switch units, set schedules and get alerts on your phone before anyone in the building notices.

Air conditioning

VRF and VRV systems. Daikin, Mitsubishi Electric, Samsung, LG, Panasonic, Fujitsu, Toshiba, Hitachi and more.

Hydronic and geothermal

Heat pumps, underfloor and radiator loops, and geothermal plant. Stiebel Eltron, Midea and Olympia Splendid.

Smart home and BMS

Native drivers for Control4, Savant and Basalte. KNX, BACnet and Modbus for everything else.

AirNexus supplies the gateway and the Nexus iQ platform. Your existing system stays exactly as it is.
