AirNexus turns any home or building into a precision climate system — every room, every zone, controlled from your pocket or from anywhere in the world. Built for ducted air conditioning, VRV/VRF systems, hydronic heating and fan-coil units, AirNexus gives you room-by-room comfort that ordinary thermostats can't touch. Set the temperature you want in each zone and let the controller do the rest: balancing airflow, staging heating and cooling, and proving the system is actually delivering before it opens a single damper. WHOLE-HOME, ROOM BY ROOM Control up to 32 independent zones from one beautifully simple app. Mix damper zones, hydronic circuits and individual fan-coil units on the same system — each with its own temperature, mode, fan speed and schedule. WORKS EVERYWHERE — EVEN OFFLINE Control your system from the couch or from another continent over a secure connection. On-site, the controller keeps running your schedules and comfort settings even if the internet drops. No cloud outage takes your heating offline. SMART SCHEDULES & AUTOMATIONS Set warm mornings and cool nights per zone with simple day-and-time schedules. Create if-this-then-that automations from live system data — trigger a zone, stage a pump or push yourself a notification when a temperature crosses the line. WORKS WITH YOUR SMART HOME Pair with Apple Home, Google Home and Amazon Alexa over Matter, and integrate with Control4 and other professional systems. Ask your voice assistant, tap a HomeKit scene, or build it into whole-home automation. HYDRONIC & PLANT CONTROL Drive zone valves, pumps, ring-main circulators, backup heaters and mixing valves with weather-compensated heat curves. Monitor heat pumps, buffer tanks and solar inverters right alongside your zones. SEE EVERYTHING Live diagnostics show exactly what your system is doing — damper positions, airflow, supply and return air, sensor readings and a full change log of who changed what and when. A live I/O board shows every input and output in real time. BUILT FOR INSTALLERS, LOVED BY OWNERS Fast on-site commissioning over Wi-Fi, deep installer configuration, and an interface clean enough that anyone in the house can use it. AirNexus — comfort in every room, control in your hand. ## Version history (last 5 releases) ### 5.2.6 — 2026-07-21 This update adds a complete solar and energy package plus a full EV charger controller, with schedule and Olympia Splendid improvements. EV charger (new) - Set up your car charger as its own plant with live tiles: charge power, car battery percent, time to full, and session and daily energy. - Charging profiles: Solar (follow your spare solar), Solar plus Floor, Boost (max), Custom kW, Off-Peak Only, and Price Cap. - Smart limits: charge up to a target percent, always keep the car above a minimum percent, and never charge in peak. - Charging cost from your tariff, with a solar versus grid split and the money saved by charging on the sun. - Combined graph of car, solar, grid and home battery power. Sungrow solar and energy - New tiles for all inverter data: solar, battery, grid, PV strings, plus today and lifetime energy. - Tap any node on the Power Flow screen to open its graph. - New Energy Rates screen for peak, shoulder and off-peak times and rates, feed-in tariff and daily supply charge. - New Cost report with running costs for today, this week and this month. Schedules and presets - Power (On and Off) is now separate from Mode. - Set any of Power, Mode, Setpoint or Fan Speed to Not used, so a schedule changes only what you choose. - Setpoint range widened to 0 to 100. - Schedule and preset menus now slide up so every option is easy to reach. Olympia Splendid - New energy and efficiency tiles (COP, SCOP, and kWh produced, consumed and renewable) and a dedicated Energy tab. ### 5.2.5 — 2026-07-19 • Matter accessory pairing and smart-home improvements. • More reliable push-notification automations on iPhone. • Faster, more stable performance across all your zones, plus a range of fixes and refinements. ### 5.2.4 — 2026-07-17 • Fixed the crash when creating or saving a notification automation on iPhone — automations now build and save reliably. • Smoother, more stable navigation across the app. • Performance and reliability improvements throughout. ### 5.2.3 — 2026-06-24 • Installer settings now save only what you configure — no stray default addresses or duplicate-output warnings. • Reducing the FCU/zone count fully removes deleted zones and their mixing-valve setup. • VRF zones support "Other Zone Sensor" and "Average" sensor references, matching hydronic zones. • Adding a device is correctly limited to controllers registered with AirNexus. • Fixed a freeze when saving a push-notification automation on iOS. • Stability and reliability improvements. ### 5.2.0 — 2026-04-29 Version 5.2.0 What is new: • Demo Device mode — try AirNexus end-to-end without any hardware. Pick "Demo Device" on the Locations page to provision a fully simulated VRV plant with zones, a Sungrow solar inverter and a Stiebel heat pump. • Power Flow page for solar inverters — live solar / grid / home / battery visualisation with smooth animated arrows. • Central Control sheet — adjust mode, fan speed and setpoint for every zone in a plant from a single screen. • Bigger, refined tablet layout across zones, plant info, and master controls — better use of landscape space on iPad. • Refreshed visual style for Locations, Add Device, Zone & Damper Info, Stiebel ISG settings, Network settings, App settings and the side menu. • Light theme polish across logs, charts and device tiles — no more black-on-black icons. • iOS Bluetooth permission flow rewritten — fixes the "Permission denied" issue when commissioning gateways on iPad. • Many smaller fixes and stability improvements. ## Related topics [airnexus](https://appshunter.io/ios/topics/airnexus) --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
