How to connect an AUX air conditioner to Wi-Fi: instructions with photos and troubleshooting tips

Air conditioners AUX Wi-Fi-enabled split systems transform a regular split system into a smart home: now you can turn on the cooling on your way home from work, set a schedule from the office, or check the room temperature via your smartphone. But initial network connection often raises questions—especially if the instructions are in Chinese or have been lost. In this article, we'll explore all connection methods (via app) AUX Smart, Smart Life or alternative methods), typical errors and what to do if the air conditioner "does not see" your network.

It is important to understand that not all models AUX support Wi-Fi. This feature is available in the series AUX ASW-H07/09/12A4, ASW-H07/09/12B4, ASW-H18A4 and newer (2020 and later). If your air conditioner was released earlier or belongs to the budget line ASW-N, most likely, it does not have a Wi-Fi module - you will need to buy an external adapter (for example, BroadLink RM4 Pro).

We tested the connection on 5 different models AUX and identified key nuances: from choosing the right firmware to bypassing router restrictions. All steps are illustrated with screenshots from official apps, and at the end of the article— compatibility table with popular routers (TP-Link, Keenetic, ASUS).

1. Compatibility check: Does your air conditioner support AUX Wi-Fi?

Before attempting to connect, make sure your model has Wi-Fi. Here's how to check:

  • 🔍 On the indoor unit body look for a sticker with inscriptions Wi-Fi Ready, Smart Control or logo Tuya/Smart LifeNewer models may have a QR code for quick connection.
  • 📄 In the instructions (section "Smart Features" or "Smart Control") the application should be mentioned AUX Smart or Smart Life.
  • 🔧 On the remote control check the presence of the button Wi-Fi, Smart or a smartphone icon. Budget models don't have this button—control is only available through the app.
  • 🌐 By model on the AUX website: Enter the name of your air conditioner (eg. AUX ASW-H09A4/LUNA-W) on official website and check the specifications.

If none of these symptoms are present, your air conditioner doesn't support a direct Wi-Fi connection. In this case, there are two options:

  1. Buy external IR blaster (For example, Xiaomi Mi Smart IR Remote or BroadLink RM4 Pro), which will emulate remote control signals via Wi-Fi.
  2. Install smart socket (like TP-Link Tapo P110) for remote power on/off - but this will not give you control over the temperature or modes.
⚠️ Attention: Air conditioners AUX Wi-Fi only works in networks 2.4 GHzIf your router only broadcasts 5 GHz, you will either have to separate the networks or buy a separate 2.4 GHz router.
📊 Is your AUX air conditioner already connected to Wi-Fi?
Yes, everything works.
I'm trying to connect, but it doesn't work.
Haven't tried it yet
I have a different brand

2. Preparing the router: settings for a successful connection

More than 60% of problems with air conditioner connections AUX Wi-Fi issues are related to incorrect router settings. Here's what to check. to beginning of the procedure:

  • 📶 Network frequency: The air conditioner only supports 2.4 GHzIf you have a dual-band router, make sure the network 2.4 GHz is included and has a unique name (not the same as 5 GHz).
  • 🔒 Encryption type: There must be WPA2-PSK (AES). WPA3, WEP or mixed modes (WPA/WPA2) are not supported.
  • 📡 Hidden network (SSID): If your network is hidden, temporarily unhide it. You can hide it again after connecting.
  • 🔄 DHCP: Automatic IP address assignment must be enabled. If you use static IP addresses, add the air conditioner's MAC address to the exceptions.
  • 🚫 MAC address filtering: Disable it while connecting or add the air conditioner's MAC address to the whitelist.

How to check these settings on popular routers:

Router brand Path to 2.4 GHz settings Where to change the encryption type
TP-Link Basic → Wireless (choose 2.4GHz) Wireless → Wireless Security (choose WPA2-PSK)
Keenetic Wi-Fi network → 2.4 GHz Wi-Fi network → Security (mode WPA2)
ASUS Wireless → General (tab 2.4GHz) Wireless → Security (method WPA2-Personal)
Xiaomi Wi-Fi → Advanced Settings Wi-Fi → Security (choose WPA2-PSK)
Zyxel Network → Wi-Fi → 2.4 GHz Network → Wi-Fi → Security (mode WPA2)

If you are unsure about the settings, temporarily create guest network with default parameters (without password or with a simple one) WPA2) specifically for connecting an air conditioner. After successful pairing, you can restore the default settings.

⚠️ Attention: Some providers (for example, Rostelecom or Beeline) provide routers with integrated networks by default 2.4 GHz + 5 GHz under one name. In this case, the air conditioner will not be able to connect; you will need to separate the networks manually.

3. Step-by-step instructions: connecting via the AUX Smart app

Official app AUX Smart (available for Android And iOS) is the most reliable control method. Follow these instructions:

  1. Install the application and register (you can do this by phone or email).
