Faikin Ninja — Pairing and Network Guide

Faikin Australia

Getting a Faikin Ninja (P1P2 for Daikin, X-Y for Mitsubishi Heavy) onto your WiFi, and into Apple Home, Google Home or Home Assistant, including how to factory reset it and pair it again.

All control is local · no cloud, no account · the QR on your module's sticker works for life.

Two builds, and they get onto your WiFi in different ways. You chose one at purchase and it cannot be changed afterwards.

WiFi build - broadcasts its own setup network, so it joins your WiFi on its own with no hub involved. Sections 1, 5 and 6 apply to you; sections 2 to 4 do not.

Matter build - has no setup network, and is handed your WiFi details during Matter commissioning, so a Matter hub is what brings it online. The whole of this page applies to you.

1. Read the LED, then the label

When the module powers up, the LED flashes yellow-green four or five times, then settles to blue and red, alternating. Blue and red alternating means the module is ready to pair. Every Faikin module does this, whichever build it is, so the LED tells you the module is ready but not which build you have. The label tells you that.

LED at power-up	Meaning	What to do
Four or five yellow-green flashes	Starting up.	Wait a few seconds.
Blue and red, alternating	Ready to pair. The module has no WiFi details yet. This is the normal state of a new module, or of one that has just been reset.	Check the label to find your build, using the table below.
A single blue flash	Older firmware. The module is ready to pair in the same way.	Check the label and pair as below. Once the module is online, update it from the Firmware Upgrade menu on its web page.

On the label	Build	What to do
A Matter QR with an 11-digit code beside it	Matter build. It does not broadcast a WiFi network, and its Bluetooth is the special low-energy kind that only smart-home apps can detect, so it will not appear in your phone's Bluetooth list the way headphones would. Both of these are normal.	Pair by scanning the Matter QR from Apple Home, Google Home or another Matter app. See sections 2 and 4. WiFi is set up as part of the pairing itself.
An Apple Home QR with an 8-digit code beside it, and a network name starting FaikinAC followed by four characters	WiFi build. It broadcasts its own network, named FaikinAC followed by four characters, and joins your home WiFi through that. It has no Matter, so it cannot be added to Google Home, Alexa, SmartThings or Aqara.	Join that network from your phone and the setup page opens. Enter your home WiFi name and password. From then on use the local web page, MQTT, Home Assistant, or Apple Home by scanning the Apple Home QR on the label. For Apple Home, first switch HomeKit on (see section 6). Sections 2 to 4 below do not apply to you; section 5 covers factory reset.

2. Pairing with the Matter QR

This section is for the Matter build. The sticker on the side of the Ninja carries a Matter QR, with an 11-digit Matter code beside it as a fallback. Pair with the Matter QR, whichever ecosystem you use: Apple Home, Google Home, Alexa, SmartThings, Aqara or Home Assistant all accept it.

Before you start: make sure your phone is currently on the WiFi network you want the Ninja to use. It needs to be a 2.4GHz or mixed network. Phones sometimes flip between networks without telling you, so check it in your WiFi settings right before pairing.

To pair: open your app, tap the + button to add a device or accessory, then point the phone camera at the Matter QR code on the sticker. If the QR will not scan, type the 11-digit code in by hand instead.

Once the pairing process finishes, the Ninja joins your WiFi and integrates itself into your smart home.

3. Network requirements checklist

This checklist is for the Matter build. Before pairing, make sure of the following. These cover the great majority of failed or timed-out pairings.

Requirement	Must / recommended	Detail
Bluetooth on, phone near the module	Must	Pairing starts over Bluetooth. Stand within a few metres.
Phone joined to the WiFi you want the module on	Must	The pairing passes that network's name and password to the module. Phones sometimes flip between networks without telling you, so check this in your WiFi settings right before you start.
The WiFi name broadcasts on 2.4GHz	Must	A combined 2.4/5GHz network is fine, and your phone can be on the 5GHz side. A 5GHz-only network will not work.
Security WPA2, or mixed WPA2/WPA3	Must	Pure WPA3-only networks do not work. Mixed (transition) mode is fine.
IPv6 enabled on the router	Must	Matter requires it. It is on by default on most home routers.
No client or AP isolation on the WiFi	Must	Devices on the network must be able to see each other. Guest networks commonly have isolation on, so avoid pairing onto a guest network.
One VLAN while pairing	Must (if you run VLANs)	Put your phone, the module and any hub on the same VLAN or subnet while pairing.
Leave the module on DHCP (automatic IP)	Must	A static IP set on the module's own WiFi page blocks its internet access on some routers, which stops MQTT and firmware updates. If you want a fixed address, use a DHCP reservation in your router instead.
VPN off on your phone	Recommended	Phone VPNs and private relays can break local discovery during pairing.
Hub powered, same WiFi, up to date	Recommended	If you use an Apple TV, HomePod or Google hub, have it on and updated before you start.
Location services on	Recommended (Android only)	Android needs it for Bluetooth scanning.

4. Do you need a hub?

Only on the Matter build, and only because Matter needs a controller in your home to hand the module your WiFi details. The WiFi build needs no hub at all. Whether you need to buy one depends on your ecosystem, and you may already own one without knowing.

Apple Home

An iPhone or iPad on iOS 18 or newer pairs the module and controls it on its own while you are at home, no extra hardware needed. An Apple TV or HomePod (any model) adds control when you are away from home and rock-solid day-to-day operation, so use one if you have one.

Google Home

Google requires a physical Google hub, the app will not complete pairing without one on your account. Any of these works: Google TV Streamer (4K), Nest Hub (1st or 2nd gen), Nest Hub Max, Nest Wifi Pro, Nest Audio, Nest Mini, Google Home or Google Home Max. An Android phone on its own cannot do it.

Hubs you may already own

Many newer Samsung TVs, Smart Monitors and Family Hub fridges contain a SmartThings hub. Pair through the free SmartThings app.
Amazon Echo speakers from about the 3rd generation onward are Matter controllers. Pair through the free Alexa app.
An Aqara Hub M3 is a full Matter controller and works across ecosystems. Note the earlier Aqara hubs (M2 and older) are not, they cannot add the Ninja.
A Home Assistant server (even on an old PC) has a Matter controller built in, and also finds the module over MQTT with no Matter involved at all.

Two that do not work: the IKEA Dirigera is a Matter bridge rather than a controller, so it cannot add the Ninja. Tuya and Smart Life hubs cannot commission it either, despite their Matter branding.

Strictly Android household with none of the above? Order the WiFi build, which brings itself online without a hub, or contact us and we will walk you through the options.

5. Factory reset and re-pairing

This section applies to both builds. A factory reset clears all of the module's settings, including its WiFi details, pairings and MQTT details, but not its identity. The QR on the sticker is permanent, so a reset is simply a fresh start.

How to factory reset the module

Faikin Ninja module label with the reset button marked at the top left, next to the QR code

The reset button is the small raised round button moulded into the case at the top left of the label, beside the QR code.

Leave the module wired in and the air conditioner powered. The module runs from the unit's power, so it needs to be on for the reset to work.
Find the reset button: a small, slightly raised round button moulded into the case at the top left of the label, next to the QR code.
Press and hold it with your fingertip for 15 seconds. Do not use a paperclip or anything sharp.
Let go. The module restarts with its factory settings.

Matter build: pairing again

Remove the old accessory from the app first. Open Apple Home or Google Home and delete the module's old entry, including any half-added ones. A reset module will time out against a stale entry every time, and this is the most common cause of failed re-pairing.
Run the checklist in section 3.
Pair again by scanning the Matter QR on the sticker.
If you use Home Assistant over MQTT, open the module's web page once it is back on your WiFi and enter your broker details again under Setup > MQTT.

WiFi build: setting up again

The FaikinAC setup network comes back after the reset. Join it from your phone and enter your WiFi name and password again.
If you use Apple Home, remove the module's old accessory from the Home app, then switch HomeKit back on under Setup > Others, Save and Reboot, and scan the Apple Home QR again (see section 6).
If you use Home Assistant over MQTT, enter your broker details again under Setup > MQTT.

6. After pairing: the web dashboard

The moment the module is on your WiFi it has its own local control page, independent of any smart-home app. This applies to both builds.

Browse to http://faikinac-xxxx.local, where xxxx is the four-character code on the module's sticker.
If .local does not load, open your router's admin page or app, find the device list, and note the IP address next to FaikinAC-xxxx (something like 192.168.1.57). Browse to that IP instead.
Bookmark it, or use your phone browser's Add to Home Screen, and it opens like an app from then on.

The page works from any device on your network, Android, iPhone, Windows or Mac, and never needs the internet. Home Assistant users can also connect over MQTT, set up from the module's Setup page.

WiFi build: switch Apple Home on before you pair it. HomeKit is off by default, and the Apple Home QR on the label will not pair until you turn it on.

Once the module has joined your WiFi, open its web page as above.
Go to Setup > Others and switch HomeKit on.
Press Save, then Reboot.
In the Home app, tap +, then Add Accessory, and scan the Apple Home QR on the label. If it will not scan, choose More options and type in the 8-digit code next to it.

The Matter build needs no toggle.

7. Troubleshooting

If Matter pairing does not work first time, work through the steps below. Matter is very new technology and networks need to be configured specifically for it. Routers even just a few years old may struggle, and certain brands like UniFi can be tricky, but not impossible, to get working. If everything else fails, ping Andrew with your router model number.

Symptom	Likely cause and fix
Apple Home will not accept the Apple Home QR (WiFi build)	HomeKit has not been switched on. On the module's web page go to Setup > Others, switch HomeKit on, then Save and Reboot, and scan the QR again.
Pairing times out on a previously-paired module	Stale entry in the app. Remove the old accessory from Apple Home / Google Home and try again.
Google Home refuses to start pairing	No Google hub on the account. See section 4.
QR will not scan	Type in the code printed next to the QR instead: in Apple Home choose More options, then set up without a code. That is 11 digits on the Matter build, 8 digits on the WiFi build.
Times out on a fresh module with everything correct	Usually the network: your phone slipped onto a different WiFi network, isolation on the WiFi, WPA3-only security, IPv6 off, or a router that blocks discovery traffic (some UniFi setups are known for this). Work through section 3, or tell us your router model.
MQTT shows Disconnected, or firmware update finds nothing	If a static IP is set on the module's WiFi page, that is the cause: on some routers it blocks the module's internet access. Clear the static IP fields (keep your WiFi name and password), save and reboot, then reserve the address in your router if you want it fixed. If you need a static IP, connect on DHCP and update the firmware first.
No FaikinAC network appears, and nothing shows in the phone's Bluetooth list	Normal on the Matter build. It never broadcasts a WiFi network, and its Bluetooth is only visible to smart-home apps. Check the label (section 1) and pair from the app by scanning the Matter QR on the sticker.
No Matter option anywhere, and the Matter app will not find the module	Check the label (section 1). The WiFi build has no Matter, so it cannot be added to Google Home, Alexa, SmartThings or Aqara. Join its FaikinAC setup network instead, then use the local web page, MQTT, Home Assistant or Apple Home.
Paired, but the aircon will not respond to commands	Open the module's web page and check Setup > Activation Code is present. Reading works without it, control does not.
You want to start again from scratch, or the module is stuck after a failed setup or a move to a new router	Factory reset it by pressing and holding the reset button beside the QR on the label for 15 seconds, then set it up again. See section 5.
