In this article, we'll look at all stages: from preparing equipment to solving typical errors that interfere with synchronization.

It is important to understand that not all air conditioners Samsung support remote control. This feature is only available for models with a module. Wi-Fi (usually these are series AR, AQ, Wind-Free and others marked Smart (in the title). If your air conditioner was manufactured before 2018, it will most likely require an external adapter - for example, Samsung Smart Wi-Fi Adapter (model AX56-00300A). You can check compatibility by serial number on the official website or in the documentation.

Not all models Samsung are equipped with a built-in Wi-Fi module. To avoid wasting time, first check whether your equipment is compatible with remote control. Here are the key signs of compatibility:

  • 📱 SmartThings-enabled series: all air conditioners with a set-top box Smart in the title (for example, Samsung AR12TXHQAWQNER Smart Inverter) or with a logo Wi-Fi Ready on the body.
  • 📅 Year of release: models from 2018 and newer (except for some budget series, released before 2020).
  • 🔧 The presence of a Wi-Fi button: there should be an antenna icon or inscription on the remote control or control panel Smart.
  • 🔄 External adapter: for older models (2016–2017), you can purchase an adapter Samsung Smart Wi-Fi Adapter (suitable for series AR9, AQ9 and others).

⚠️ Caution: Wi-Fi adapters from third-party brands (e.g. Tuyatec or Sonoff) may conflict with the firmware SamsungUse only original accessories or certified solutions.

Preparing for connection: router, smartphone, and air conditioner

Before setting up, make sure all devices are ready to sync. Most often, problems arise due to incorrect router settings or outdated software on your smartphone. Here's a checklist for preparation:

Make sure the air conditioner is plugged in and running in cooling/heating mode|

Check that your router is distributing the network in the 2.4 GHz range (5 GHz is not supported!)|

Update the SmartThings app to the latest version in the App Store/Google Play|

Disable VPN, proxy, or corporate networks on your smartphone|

Place the router closer to the air conditioner (distance no more than 10 meters)|

Make sure Bluetooth is enabled on your smartphone (required for initial setup)-->

Pay special attention to your router settings. Air conditioners Samsung work only with networks 2.4 GHz and do not support modern safety standards WPA3 or 802.11acIf your router distributes the network in two ranges (2.4 and 5 GHz) under one name (SSID), will have to divide the networks in your router settings. Here's how to do it:

  1. Go to the router's web interface (usually at 192.168.0.1 or 192.168.1.1).
  2. Find the section Wi-Fi or Wireless network.
  3. Activate the option Split 2.4 GHz and 5 GHz (or Enable Separate SSID).
  4. Give your 2.4GHz network a unique name (e.g. MyWiFi_2G).
  5. Set the security type WPA2-PSK (Not WPA3!).
  6. Save the settings and reboot the router.

If your router doesn't support split-band, you can temporarily disable the 5 GHz network while you configure the air conditioner. Also, check that the router settings disabled:

  • 🔒 MAC address filtering (may block the air conditioner connection).
  • 🔄 Client isolation mode (AP Isolation).
  • 📡 Hiding the SSID (the network must be visible).
⚠️ Please note: Some providers (eg. Rostelecom or Beeline) by default, protection against connections from "unknown" devices is enabled. If the air conditioner doesn't find the network, temporarily disable this option in your provider's personal account.
