What is the Faikin Ninja and who is it for?
It is a small module that gives you local control of air conditioners that run from a wired wall controller over a two-wire control bus. There are two versions, same module and same software, different bus:
- Faikin Ninja P1P2 for Daikin systems on the P1/P2 bus: VRV/VRF, Sky Air, and ducted and cassette systems run from a wired wall controller such as a BRC1E. It also reaches older Daikin systems with no X50A port, or with the blue X50A port that the standard cable cannot use. These are the systems the standard Faikin Faikout cannot reach.
- Faikin Ninja MHI X-Y for Mitsubishi Heavy Industries systems on the two-wire X-Y bus: the FD series (FDU, FDT, FDUA, FDK and similar) and MHI VRF. The five-wire CNS/SPI splits, such as SRK and DXK, are not covered.
More brands are on the way.
How do I know whether I need the P1P2 or the MHI X-Y version?
By brand and by the terminals your wall controller uses. A Daikin with terminals marked P1 and P2 takes the P1P2 version. A Mitsubishi Heavy Industries unit with terminals marked X and Y takes the MHI version. If your MHI indoor unit has five wires running to the controller rather than two, it is a CNS/SPI split and neither version fits.
Not sure? Send us the indoor unit model number and a photo of the wall controller wiring and we will tell you.
Do I need the module, the cable, or the kit?
For the Daikin P1P2 version:
- Module only (A$135) — if you want to make your own two-wire connection to P1/P2.
- Cable (A$25) — a ready-made lead if you already have a module.
- Module and cable kit (A$149) — everything together, at a saving.
The MHI X-Y version lands on plain screw terminals, so it does not use a pre-made cable. Email us for pricing and availability.
Blade or Forked — which cable?
This applies to the Daikin P1P2 cable. The module taps onto the P1/P2 bus, which runs between the indoor unit and the wired wall controller, so you can connect at whichever point is easier to reach. Both give identical control.
- Blade (indoor unit) — flat blade terminals for the P1/P2 terminals on the indoor unit's control board.
- Forked (wall controller) — fork terminals for the screw terminals behind a wired wall controller. Often easier on ducted and cassette systems where the indoor unit is hard to reach.
Not sure? Send us your indoor model and wall controller and we will point you to the right one.
What smart-home apps does it work with?
Both versions work with the major smart-home apps — Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, Aqara and Home Assistant — with no bridge or hub and no cloud account. Home Assistant and Node-RED are also supported directly over MQTT, and there is a local web interface.
Will my existing wall controller still work?
Yes, in the normal case, and this is the same on both versions. The module sits on the bus alongside your existing wired wall controller and does not replace it. The module in fact needs a main controller on the bus, so keeping your wall controller is exactly right.
The one thing to know is the two-device limit: the bus takes a maximum of two control devices, one main and one sub. A standard wall controller plus the module is two, so that works. If there is already a second device on the bus, such as an infrared receiver, it has to come off. On Daikin it only becomes a choice if you also have a zone controller, see the next question.
Can it control my ducted zones?
On Daikin, yes. Systems with a BRC24-style zone controller let the module open and close individual zones, so you can run them from your app or automations. Zone support for other brands, including MHI, is coming.
Because the bus takes only two control devices, a Daikin zone controller plus a standard wall controller plus the module would be three. In that case the zone controller stays as the main device and the standard wall controller comes off the bus. You keep physical zone control from the zone panel, and you gain full app and Home Assistant control through the module. If you do not have a zone controller, nothing changes: your wall controller stays and the module simply joins as the second device.
Does it work with IFTTT?
Not directly — IFTTT does not speak the module's local protocols. You can still automate it through IFTTT via Home Assistant, which controls the module over MQTT and connects to IFTTT with webhooks, or through your voice platform once the module is added to Google Home, Amazon Alexa or Samsung SmartThings.
Do you set it up for me, or do I do it myself?
Your choice, and it is set per module:
- I will set it up myself (no charge) — the module arrives ready for the local web interface, MQTT and Home Assistant.
- Matter and Apple Home compatible (A$12.50) — we provision it before dispatch so you can add it to Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, Aqara and other major apps. You finish setup by scanning a code in the app of your choice.
The firmware supports Apple Home and the other major platforms together, so you do not have to choose between them. There is no licensing fee — the A$12.50 simply covers our time to provision the module for you.
Can I get an Ethernet, KNX or Tuya version?
Yes, on both the P1P2 and the MHI X-Y module, but all three are special orders. They are not stock items and are not on the product page, so email us before you order and we will quote and build one.
- Ethernet — a wired network socket in place of Wi-Fi. You plug it into your router or switch and skip Wi-Fi setup entirely; everything else behaves the same.
- KNX — adds a KNX bus connection. ETS 6.2 or earlier.
- Tuya — adds SmartLife and Tuya Smart app support. This is the only option that uses a cloud service.
Do I need to flash the firmware, or can I flash it myself?
Neither — there is no firmware for you to flash. Every module ships pre-provisioned and tested. When you order, choose your setup option and we load the right build before dispatch: set it up yourself (ready for the local web interface, MQTT and Home Assistant), or Matter and Apple Home compatible for Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, Aqara and others. After that, firmware updates arrive automatically over the air, so it stays up to date on its own.
Do I need a hub or bridge?
No bridge or hub is needed for local control. Some apps use a home hub for remote access and automations (for example an Apple hub such as a HomePod or Apple TV, or a Nest speaker or Hub for Google Home), the same as any other accessory.
How does it install?
It connects to two terminals, at the indoor unit or the wired wall controller, and is powered from the unit (12–16V DC, under 1W). On Daikin those are P1 and P2; on MHI they are X and Y. Neither is polarised, so the two wires can go either way round. The bus is low voltage, but always isolate the system at the breaker before opening anything. If you are not comfortable working inside the unit or controller, use a qualified installer.
Step by step: the P1P2 installation guide or the MHI X-Y installation guide.
What are the returns and warranty terms?
No-risk returns apply if it does not work in your setup.
How do I check my model is compatible?
Compatibility is confirmed per indoor model. Send us your model number and controller and we will check, or use the compatibility and cable-selection database on our site.
