NodOn Zigbee AC Infrared Controller Review: A Zigbee Thermostat for Any Infrared Split Unit

The verdict

The NodOn Zigbee AC Infrared Controller (IRB-4-1-00) brings a split air conditioner or air-to-air heat pump into a Zigbee smart home without replacing it. It recognises the unit's infrared codes from a built-in library or learns them from the original remote, creates a virtual remote on the Zigbee gateway, and adds built-in temperature and humidity sensing for room-aware automations, all under local control. The catch is that it is not standalone: it needs a Zigbee coordinator such as Home Assistant or Zigbee2MQTT, it is infrared only, and it has no Matter, Apple Home, Google Home, Alexa or SmartThings support.

Best for
  • Zigbee homes with a split air conditioner
  • Home Assistant and Zigbee2MQTT users
  • Retrofitting an AC without replacing it
  • Local-only automation
Buy on Amazon UK

Pros

  • Turns an infrared split or air-to-air heat pump into a Zigbee climate device
  • Recognises IR codes from a library or learns them from the original remote
  • Built-in temperature sensor with 17°C to 30°C setpoints
  • Humidity reading exposed to the gateway
  • 360° IR emitter plus an external IR port
  • Local control through Home Assistant or Zigbee2MQTT
  • 2 year warranty

Cons

  • Needs a Zigbee hub or coordinator
  • Infrared only, no RF remote support
  • No Matter, Apple Home, Google Home, Alexa or SmartThings support
  • Needs line of sight to the air conditioner

Who is the NodOn Zigbee AC Infrared Controller for?

It is a retrofit device for a home whose air conditioning answers only to an infrared handset and that already runs a Zigbee network. NodOn lists Home Assistant, Zigbee2MQTT, Jeedom and Edalso as compatible gateways, and Zigbee2MQTT exposes this exact model as a climate device, so mode and temperature can be automated against other sensors in the house. It is a poor fit for anyone without a Zigbee hub or for a setup built on Apple Home, Google Home, Alexa or SmartThings.

What the NodOn Zigbee AC Infrared Controller offers

Its universal remote function recognises or learns the infrared codes of any infrared split or air-to-air heat pump and creates a virtual remote on the Zigbee gateway; when the built-in library has no match, manual learning captures the codes from the original remote. A 360° infrared emitter covers line-of-sight control of the unit, with an external IR port for a wired emitter. A built-in temperature sensor reads the room from 0°C to 40°C and drives the 17°C to 30°C climate setpoints, and a humidity value is exposed too. Bluetooth Low Energy pairs it with the NodOn Climate app for infrared setup and firmware updates. It measures 90 x 70 x 25.5 mm, weighs 67 g and carries a 2 year warranty.

What to know before you buy

It is a Zigbee 3.0 end device, not a coordinator, so it does nothing until it joins a compatible gateway, and it has no Wi-Fi or Ethernet. It is infrared only, with no radio-frequency remote support, and infrared is line of sight, so it has to sit in the same room as the split unit with a view of its receiver. There is no Matter path and no Apple Home, Google Home, Alexa or SmartThings compatibility, so its reach runs entirely through the Zigbee gateway.

Is the NodOn Zigbee AC Infrared Controller worth it?

For a Zigbee household with a non-smart split air conditioner, it solves the problem cleanly: a local device that behaves like a thermostat, with its own temperature and humidity readings, and works with almost any infrared unit thanks to the code library and manual learning. Without a Zigbee network, the cost of adding a coordinator changes the maths.

Frequently asked questions

Does the NodOn Zigbee AC Infrared Controller need a hub?

Yes. It is a Zigbee 3.0 end device, so it needs a compatible coordinator or gateway. NodOn lists Home Assistant, Zigbee2MQTT, Jeedom and Edalso.

Which air conditioners does it work with?

Any infrared split air conditioner or air-to-air heat pump. It recognises the codes from its library, and manual learning captures them from the original remote when there is no match.

Does it work with Home Assistant?

Yes, through ZHA and through Zigbee2MQTT, which supports the exact IRB-4-1-00 model and exposes it as a climate device.

Does it work with Alexa, Google Home or Apple Home?

No. It is not compatible with Alexa, Google Home, Apple Home or SmartThings, and it has no Matter support.

Does it measure temperature and humidity?

Yes. A built-in temperature sensor reads the room from 0°C to 40°C, and a humidity value is exposed to the gateway.

Why it needs a Zigbee coordinator

The NodOn Zigbee AC Infrared Controller speaks Zigbee, not Wi-Fi. On its own it cannot reach your phone, your voice assistant or any automation: it needs a Zigbee coordinator to join. These are the ones in our catalog that can run it.
