Local Control Guide
The AC controller works on your home network without the internet and without an NH account. This guide covers the three local ways to use it and what each one needs.
Choose how to use it
| Option | You need | What you get |
|---|---|---|
| Home Assistant | Home Assistant and an MQTT broker (such as Mosquitto) | Control and automations in Home Assistant; data stays at home |
| Apple Home (HomeKit) | An iPhone with the Home app | Control from the Home app or Siri, without NH servers |
| Status page | Any phone or computer with a browser | Device status and settings |
| NH app (cloud) | An NH account and the app | Remote control, history, alerts, schedules, automatic firmware updates |
You can combine them, for example Home Assistant and Apple Home together. MQTT connects to one place at a time, either your own broker or the NH cloud, never both.
Local modes don't contact NH
With "Local MQTT (Home Assistant)" or "No MQTT", the controller never connects to an NH server, including for firmware update checks. Automatic firmware updates run only in cloud mode (with the NH app).
Open a pairing window with the AC remote
You set the controller up with the air conditioner's own remote, without pressing any button on the controller. Set the AC to:
- On
- Cool mode
- 30 °C
- Low fan
After about 3 seconds the controller opens a 15-minute pairing window. Setup and setting a first admin password only work while it's open; it closes by itself.
