Connecting Xiaomi Smart Home to Marus: A Complete Guide to Solving Typical Errors

Voice control of a smart home is no longer a fantasy: you can turn on the lights, adjust the temperature or run a robot vacuum cleaner with a simple voice request. The Xiaomi Smart Home ecosystem and Marusya's VK assistant are one of the most convenient combinations for automating everyday life. However, their integration does not always go smoothly: users face problems with device synchronization, authorization errors or scripting problems.

In this article, we will look at the step-by-step process of connecting, from setting up accounts to creating voice commands, and also look at hidden settings that will help avoid typical errors. Special attention will be paid to device compatibility — not all Xiaomi gadgets are directly supported by Marusay, and we will explain how to circumvent this limitation. If you have already tried to connect systems, but encountered the message “Device not found” or “Connection error”, here you will find practical solutions with explanations of the reasons.

For successful integration, you will need:

• 📱 Smartphone with installed Mi Home apps (version 6.0)+) and Marusia (last version).
• 🔌 Xiaomi smart devices (lamps, sockets, sensors, etc.) connected to Mi Home.
• 🌐 Sustainable Internet connection (2.4GHz Wi-Fi for most Xiaomi devices).
• 🔑 Xiaomi and VKontakte account (preferably with a confirmed phone number).

1. Preparation of accounts and applications

Before you link Xiaomi Smart Home and Marusya, make sure both services are properly configured. Start by checking your accounts:

In the Mi Home app, go to Profile → Settings → Region and select "Russia" (or "Mainland China" if you use firmware for China). This is critical: in the "China" region, some devices will not be displayed in Marus due to restrictions. API. If your account is linked to another region, create a new one or change your region through a new one. VPN.

Next, update the annexes:

• 🔄 Mi Home – Minimum version 6.0.100 (check out Google Play or App Store).
• 🔄 Marusya – latest version (updates are issued monthly, outdated versions may not support new devices).
• 🔄 VK – link Marusi account to the main profile VK (This will make it easier to authorize).

⚠️ Note: If you are using Mi Home from China, some devices (e.g. Xiaomi Mi Air Purifier) 3H Or Aqara Camera Hub. G2H) They may not be displayed in Marus even after successful synchronization, in which case you will have to change the region or use workarounds (see section 5).

Also check that all Xiaomi smart devices are:

• 🔌 Connected to a single Wi-Fi network (2.4 GHz).
• 🔄 Updated to the latest firmware (in Mi Home go to Device) → Settings → Update of the PO).
• 🏠 Added to one "household" (Mi Home should not have multiple profiles with the same devices).

2. Linking Xiaomi account to Marusei

The main stage is to link Xiaomi account to Marusa.

1. Open the Marusya app and go to Settings → Smart home. → Add a system.
2. Choose Xiaomi Smart Home from the list.
3. Enter the username and password from your Xiaomi account (the same as used in Mi Home).
4. Confirm access by following the instructions on the screen (may be required) SMS-code).

Once you've successfully logged in, Marusya will start scanning the devices, which can take up to 5 minutes -- don't close the app.

• 🔄 Restart the Marusya app.
• 📶 Check your internet connection (turn off) VPN, if it's on).
• 🔌 Make sure that Xiaomi devices are currently on and connected to Wi-Fi.

If after scanning, part of the devices is not displayed:

3. Compatibility of Xiaomi devices with Marusay

Not all Xiaomi gadgets are supported directly by Marusay, below is the compatibility table of popular devices (current for 2026):

If your device is not listed or marked as incompatible, there are two options:

1. Use an intermediary – for example, connect devices to Google Home or Yandex Smart Home and then link those systems to Marusya.
2. Set up automation through IFTTT — Create applets that will transmit commands from Marousi to Mi Home.

For Aqara devices (such as motion sensors or leaks), the only reliable way to integrate is to use Home Assistant with the Xiaomi Mi Home Integration plugin.

4. Set up voice commands

Once the devices are synchronized successfully, you can start creating voice commands, and Marusya supports two types of control:

• 🎤 Standard commands – predefined phrases (e.g., “Marusya, turn on the light in the living room").
• 🔧 Custom scenarios – user sequences of actions (e.g., “Marusya, Mode of the Movie" → Turns off the lights, turns on the TV and starts the robot vacuum cleaner).

To set up standard commands:

1. Open Marusya and move to a Smart Home → Devices.
2. Select a device (e.g. Xiaomi Mi Smart Bulb).
3. Click Set commands and select actions (on/off, change color, etc.).
4. Save the changes and test the team with your voice.

To create a custom scenario:

1. Go to the Smart Home → Scenarios → Create a script.
2. Add devices and actions (e.g. Lamp: turn on at 50% + Robot vacuum cleaner: start cleaning).
3. Ask a voice command (e.g., “Marusya, I’m leaving”).
4. Save and activate the script.

An example of a complex scenario for the regime of "Good Night":

Condition: Time after 22:00




Action:




1.Switch off all Xiaomi lamps




2. Set the temperature of the Xiaomi Mi Air Conditioning Companion at 22°C




3.Enable the Mi Air Purifier 4 air purifier at night




4. Activate the Aqara motion sensor (if connected via Home Assistant)




Voice command: "Marusya, good night"

⚠️ Warning: If voice commands don't work, check: 🔊 Microphone sensitivity (in Marousi settings there is noise level adjustment). 📡 Internet connection stability (delays of more than 2 seconds may interrupt command execution). 🔄 Relevance of device firmware (outdated versions may not support voice control).

💡

If Marusya does not recognize the device name (for example, says "I don't know such a lamp"), rename it Mi Home in Russian without special symbols (for example, "Lampa living room" instead of "Xiaomi Bulb #1").

5. Solving typical problems

Even with the right setup, users are faced with errors.

🔴 Problem: Devices don't show up in Marus after synchronization

Causes and solutions:

• 🔌 The device is connected to another Wi-Fi network → Reconnect it to the same network as the smartphone.
