Connecting Xiaomi air conditioner to Wi-Fi and Mi Home: step-by-step instructions

For Xiaomi air conditioning to become part of the smart home ecosystem, it needs to be connected to the Mi Home app, a process that may seem complicated due to the peculiarities of MiOT protocols, but it really comes down to a few steps.

First, make sure your router supports 2.4GHz Wi-Fi (5GHz is not suitable!) and make sure that the latest version of the Mi Home (at least 6.5.4) is installed on the smartphone.

1. Turn the air conditioner on to the network and press the Wi-Fi button on the remote (usually marked by the antenna icon).
2. Hold it for 5 seconds until the indicator on the inner block starts flashing orange.
3. In the Mi Home app, go to Profile → Add the device → Air conditioner.
4. Select your model from the list and follow the hints on the screen.
5. Connect to the temporary network Xiaomi_XXXX (password 12345678 or listed in the documentation).
6. Return to Mi Home and wait for the setup to be completed.

If the air conditioner is not connected, check the following points:

• 🔌 Router: Turn off the function AP Isolation and check that guest network mode is not enabled».
• 📱 Smartphone: In Wi-Fi settings, turn off automatic connection to other networks.
• 🔄 Firmware: Update air conditioning through Settings → Update of the Software in the annex.

Disable 5 GHz on the router|Check out the Mi Home version|Remote charge > 50%|Standby air conditioning (not cooling/heating)|There are no other Wi-Fi devices nearby (may interfere with the connection)

-->

Once connected successfully, the air conditioner will appear in the main Mi Home menu, where you can:

• 🌡️ Set the exact temperature in increments of 0.5°C (instead of standard 1)°C on the remote).
• ⏱️ Set up a work schedule for the week ahead.
• 🗣️ Manage voice via Alice, Google Assistant or Siri (requires a connection to the corresponding service).

⚠️ Note: If after connecting, Xiaomi air conditioner spontaneously turns on at night, check the settings Smart mode in the application. By default, the function Autoregulation by sensors can be activated, which responds to changes in temperature or humidity.

Voice control of the air conditioner Xiaomi: setting and commands

One of the key benefits of Xiaomi air conditioners is voice control, but it requires the right setup of both the device and the voice assistant to work properly.

First, make sure your air conditioner is connected to Mi Home and is in the same ecosystem as the voice assistant. For example, to control via Alice (Yandex), follow the following steps:

1. Open the Yandex app and go to Devices → Add the device.
2. Choose Xiaomi and sign in with the same account as you do with Mi Home.
3. Allow access to air conditioning data.
4. Wait for the synchronization (can take up to 5 minutes).

And then you can use voice commands, and here are some of them.

• 🎤 «Alice, turn on the air conditioner at 22 degrees" - setting the temperature.
• 🎤 «Alice, put the air conditioner in sleep mode – activation of night mode.
• 🎤 «Alice, turn off the air conditioner in an hour.
• 🎤 «Alice, what is the conditioner? – current condition request.

For Google Assistant and Siri, the setup process is similar, but there are nuances:

• 🔹 Google Assistant: Requires a connection via Google Home and Mi Account.
• 🔹 Siri: Only works through the HomeKit app (you need an adapter, such as HomeBridge).

If voice commands are delayed (more than 3-5 seconds), the problem may be in Xiaomi servers, in which case changing the region in the Mi Home settings to Singapore or India will help, where the ping to the cloud is usually lower.

Hidden features of Xiaomi air conditioners: what is not written in the instructions

The manufacturer does not always advertise all the features of its devices. In the air conditioners Xiaomi has several “secret” features that can be activated through the Mi Home or engineering menu.

One of the most useful is the Ion Purifier mode, which includes a negative ion generator that helps neutralize harmful particles in the air, and it activates this way:

1. Open your Mi Home and select your air conditioner.
2. Go to Settings. → Additional functions.
3. Find the Ion Cleanser and turn it on.

Another hidden possibility is manual calibration of sensors, if the air conditioner does not correctly detect the temperature in the room (for example, it shows 24).°C, when actually 26°C), the readings may be adjusted:

1. On the remote, press the Mode and Temp buttons. ↑ simultaneously for 5 seconds.
2. On the display of the internal block will appear menu SENSOR.
3. Install the Temp buttons to adjust (from -3 before +3°C).
4. Save the settings with the OK button.

Xiaomi air conditioners also have a Turbo mode for quick cooling, which doesn't always show up on the remote.

• 🔹 Click on the Mode remote before switching to Cool mode.
• 🔹 Then press the Fan Speed for 3 seconds – the fan will go to the maximum speed.

💡

If Xiaomi's air conditioner started making a lot of noise after Turbo mode was turned on, check the mounting of the internal unit. Vibration at high revs can weaken the mounting plates.

Typical Mistakes of Xiaomi Air Conditioners and How to Fix Them

Even the most reliable devices sometimes fail, and Xiaomi air conditioners are no exception — they have a number of common bugs that can be fixed on their own.

One of the most common problems is the error. E1 (failure of the internal unit temperature sensor to eliminate it:

1. Turn off the air conditioner from the socket for 10 minutes.
2. Check if the air intake is clogged (dust can interfere with the sensor).
3. If the error repeats, reset settings: press Mode and Temp ↓ 10 seconds.

Another frequent mistake — E3 (problems with the drainage system. It occurs if the condensate does not drain into the pallet:

• 🔹 Check the slope of the drainage tube (should be at least 3)°).
• 🔹 Clean the tube with wire or blow it out.
• 🔹 If the air conditioner is installed on the balcony, make sure that the tube does not freeze in winter.

Mistake. E5 indicates problems with the external unit (for example, freezing of the radiator:

1. Turn off the air conditioner and wait for complete thawing (1-2 hours).
2. Check if the outside block is covered with curtains or other objects.
3. If the problem recurs, call the wizard - the fan or pressure sensor may be faulty.

💡

If Xiaomi Air Conditioning Shows Error E6 (problems with the inverter, DO NOT attempt to repair it yourself.This may be due to high voltage in the compressor - contact the service center.

Also, users often experience that the air conditioner does not turn on after winter, the reasons may be as follows:

• 🔌 The battery sat down in the remote (even if the indicator is on, the charge may not be enough).
• ❄️ Drainage freezes - if the air conditioner was not used in winter, ice could accumulate in the tube.
• ⚡ Voltage jump - check the fuse on the board (disassembly required).

Electricity savings: how to reduce the consumption of air conditioner Xiaomi

Xiaomi Air Conditioners Are Class A+++ They're energy efficient, but even they can wind up extra kilowatts if they're not configured correctly. Here are some ways to reduce their power consumption without losing comfort.

The first rule is, choose the right temperature. The optimal range for cooling is 24-26.°C. Each degree below increases energy consumption by 5–7%, and use a ventilation mode (Fan) when the room temperature is close to comfortable – it consumes 3 times less electricity than cooling.

Second, set your timer and schedule. In Mi Home, you can program your air conditioner to:

• 🕘 Turned off 30 minutes before you woke up (savings on morning peak consumption).
• 🕒 Start 1 hour before returning home (so you don’t work all day).
• 🌙 Goes into night mode after 23:00 (reduced compressor power).

The third way is to use smart scenarios, like linking the air conditioner to the Xiaomi Motion Sensor.

• 🔄 If no one is in the room for 20 minutes, the air conditioner goes into Fan mode.
• 🚪 When opening a window (Xiaomi sensor) Door/Window Sensor) the device is automatically switched off.

💡

To check the real power consumption of the Xiaomi air conditioner, connect it through a smart socket (for example, Xiaomi Mi Smart Plug), which will show accurate data on kWh and help optimize settings.

Equally important is regular maintenance:

• 🧹 Cleaning filters every 2 weeks (contaminated filters increase the compressor load).
• 💧 Washing the heat exchanger 1 time a year (can be done independently with steam).
• ☀️ Protection of the outer unit from direct sunlight (for example, a canopy) - this reduces its heating and load.
