The Faikin P1P2 connects to the P1/P2 control bus on your Daikin VRV, Sky Air or ducted system and gives you full local control over Wi-Fi, with native Apple HomeKit, Matter and MQTT. This guide takes you from wiring to control. Read the safety notes first.

1. Before you start

Where it connects. The module wires to the two P1/P2 terminals, either on the indoor unit's control board (marked REMOTE CNTRL / P1 P2) or at your wired wall controller.

One rule about the bus. The P1/P2 bus allows two controllers, a Main and a Sub. The Faikin works as the Sub, and your wall controller stays as the Main. If there is already a Sub device on the bus, such as an infrared receiver, remove it before you fit the module.

Wi-Fi reach. The module needs a usable Wi-Fi signal where it sits (around -80 dBm or better). We strongly recommend mounting the module outside the metal indoor unit casing. The metal box is very effective at blocking Wi-Fi, so a module sealed inside it will often fail to connect or keep dropping out. Run the two wires out to the module and sit it somewhere with a clear signal.

2. Wire it in

1. Confirm the power is off at the breaker and both units are switched off.
2. Connect the module's two wires to P1 and P2 on the indoor board (or at the wall controller). The connection is not polarised, so either wire goes to either terminal. Use 24–12 AWG (0.6–2.4 mm) wire.
3. Mount the module outside the metal indoor unit casing, secured with cable ties and clear of other components, so the Wi-Fi stays strong. The metal box blocks Wi-Fi badly, so do not seal the module inside it.
4. Restore power to the system.

3. Connect it to your Wi-Fi

1. On power-up the module broadcasts its own Wi-Fi network, FaikinP1P2-xxxx, where xxxx is the last four characters of its MAC. Note that down.
2. Join that network from your phone or laptop. The setup page opens by itself; if it does not, browse to 8.8.8.8.
3. Choose your home Wi-Fi name, enter the password, and save. The module restarts and joins your network.
4. From then on, reach it at faikinp1p2-xxxx.local, or at its IP address from your router's device list.

If it does not connect: a wrong Wi-Fi name or password sends the module back to its own setup network (the password is the network name) so you can try again. To start fresh, hold the reset button for 15 seconds.

4. Choose how you control it

It works in your browser straight away. Add Apple Home, Matter or Home Assistant whenever you like.

In your web browser

Go to faikinp1p2-xxxx.local and use the Control page. Nothing else to set up.

Apple Home (HomeKit)

1. On the setup page, go to Setup > Others, switch HomeKit to ON, and Save & Reboot.
2. In the Home app, tap add (+), Add Accessory, and enter the 8-digit code for the module. If it is not stickered on the module, it should have been emailed to you.

Apple Home has no Dry or Fan Only mode, so you will see two extra switches that turn those modes on and off.

Matter

Matter needs a hub such as an Apple TV or HomePod. In the Home app tap add (+), Add Accessory, and enter the 8-digit Matter code for the module. If it is not stickered on the module, it should have been emailed to you.

Home Assistant (MQTT)

On the setup page, go to Setup > MQTT, enter your broker's IP, user and password, then Save & Reboot. The module then appears in Home Assistant automatically. If you do not have an MQTT broker yet, the Mosquitto add-on sets one up in a few minutes. Full detail is in the Faikin MQTT manual.

5. Fine-tuning

All of these live on the module's Setup page.

• Set a password — Setup > Unit > Login password.
• Temperature step — 0.5° or 1° increments, Setup > Unit.
• Temperature limits — set a minimum and maximum, Setup > Unit.
• Fan speeds (VRV / Sky Air) — if you have 4 fan speeds with Auto, set Fan Mode Option to 1; for 2 fan speeds, set it to 3, then Save & Reboot.
• Vane / swing — turn off if your unit does not use it, Setup > Unit.
• Fahrenheit — Setup > Unit > Temperature unit.
• Firmware — Setup > Firmware Update > Check New Firmware.
• Start again — Setup > Reset configuration returns the module to defaults.

6. Your data stays yours

The module runs entirely on your local network. There is no cloud account, no telemetry, and nothing leaves your home. You control your air conditioning, and so does whatever you connect it to, and that is the end of it.
