Apple Home (HomeKit)

The controller has HomeKit built in. Add it straight to the Home app on your iPhone and control it from the Home app or Siri, without NH servers.

Before you start

• This is an accessory not certified by Apple. When you add it, the Home app warns that it's uncertified; choose "Add Anyway". The warning appears only once.
• Because it isn't certified, Apple doesn't test new iOS versions with it, and a future iOS update could affect how it works.
• HomeKit is off by default. Turn it on first.
• While adding it, your iPhone must be on the same WiFi as the controller. To control it away from home, you need a home hub (HomePod or Apple TV).

Units set up locally

1. Turn HomeKit on: tick "Enable Apple Home (HomeKit)" during local setup, or later under "Settings" on the status page, then tap "Save settings" and "Restart".
2. On your home WiFi, open the status page and log in (see The status page). "HomeKit" shows an 8-digit setup code.
3. On your iPhone, open the Home app, tap + → Add Accessory → More options…, and enter the code.
4. When it warns about an uncertified accessory, choose "Add Anyway".

Units set up with the NH app

A device admin can do it all in the NH app:

1. Put your phone on the same WiFi as the AC.
2. Open the AC's page and choose "Apple Home (HomeKit)" from the menu at the top right.
3. The first time, set a device password: open a pairing window with the remote (Cool, 30 °C, Low fan), wait a few seconds, then set it in the app. The app remembers it.
4. Tap "Enable Apple Home". The AC restarts.
5. The app shows the setup code and a QR code. In the Home app, tap + → Add Accessory and scan the QR code or enter the code.

Pairing time limit

HomeKit pairing stays open for 10 minutes. After that the Home app can't find the AC to add it, though the AC keeps working normally. To open it for another 10 minutes, tap "Reopen pairing" on the status page or "Reopen pairing" in the NH app.

The AC in the Home app

• Heater cooler: on/off, cool / heat / auto, setpoint, fan speed, swing
• 送風 (fan): turning it on switches the AC to fan-only mode
• 除濕 (dry): turning it on switches the AC to dry mode

While fan-only or dry is running, the heater cooler tile shows as inactive. That's expected.

Moving it to another Home

An AC belongs to one Home at a time. To add it to a different Home:

1. Tap "Reset HomeKit" on the status page, or "Reset HomeKit pairings" in the NH app.
2. Every paired Apple device is removed and a new setup code is issued. The AC restarts.
3. Add it again with the new code.

Turning HomeKit off keeps its pairings; turn it back on and the original Home carries on. Removing the AC in the NH app with erase, or completing Local setup again from the hotspot, clears the HomeKit pairings.
