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 re-pairing after a reset.

All control is local · no cloud, no account · the code 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 and 6 apply to you; sections 2 to 5 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 first

The LED at power-up tells you which of the two builds you have. Check it before anything else, because the two are different firmware and get onto the network in different ways.

LED at power-up	Meaning	What to do
A few pale green flashes, then a steady alternating pale green and blue sequence	Matter build, ready to pair. 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 with the Matter code from Apple Home, Google Home or another Matter app. See sections 2 and 4. WiFi is set up as part of the pairing itself.
Slow blue flash (about once a second)	Earlier Matter modules show this instead. Same meaning: Bluetooth pairing mode, ready to pair.	Same as above.
Fast blue flash, then fast red flash (pale green in place of red on current firmware)	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 with the code on the label. Sections 2 to 5 below do not apply to you.

2. Pairing with the Matter code

This section is for the Matter build. The sticker on the side of the Ninja carries a Matter code, an 11-digit number with its own QR. Pair with the Matter code, 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. Re-pairing after a reset

This section is for the Matter build. A factory reset clears the module's pairings but not its identity. The code on the sticker is permanent, it is simply a fresh start.

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 with the Matter code from the sticker.

On the WiFi build a factory reset simply brings the FaikinAC setup network back. Join it and enter your WiFi details again.

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.

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
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 the 11-digit Matter code manually: in Apple Home choose More options, then set up without a code.
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 LED (section 1) and pair from the app with the Matter code on the sticker.
No Matter option anywhere, and the Matter app will not find the module	Check the LED (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.

Applies to the Faikin Ninja P1P2 (Daikin) and Faikin Ninja X-Y (Mitsubishi Heavy Industries). Need a hand? Contact us with your module's four-character code and a photo of the LED, or join the Faikin Australia WhatsApp channel.
