Connecting Xiaomi aquarium to Mi Home: full instruction with problem solving

Why Xiaomi’s Smart Aquarium Needs a Special Approach to Customization

Xiaomi’s smart aquariums are not just decorative tanks, but full-fledged ecosystems with temperature sensors, RGB lighting, aeration systems, and automated feeding. Unlike classic smart home devices (such as lamps or sockets), aquariums require two-level synchronization: first with Mi Home servers, then with Xiaomi Aquarium cloud platform to manage biological parameters.

The main difficulty is that these devices often come with a regional link to the Chinese Mi Home server (even if purchased in Europe), which means that without the correct change of region in the application, you risk getting a “Device not supported” error or limited functionality. In addition, the MiJia Smart Fish Tank series aquariums (for example, the LXZ-01 or LXZ-02 models) require a firmware update before the first connection – otherwise the sensors may not work properly.

In this article, we will not only discuss the standard addition procedure, but also unique nuances for Russian users, including bypassing geo-restrictions and setting up automation through Mi Home Automation. If you have already tried to connect an aquarium and got an error, skip the first section and go straight to solving problems.

Preparation before connection: what to check

Before adding an aquarium to Mi Home, make sure all the prerequisites are met, and neglecting this step leads to synchronization failures or loss of functionality in 80% of cases.

• 📱 Mi Home: Must be at least 6.5.400 (check Google Play or App Store) Older versions don't support protocol BLE Mesh used in aquariums.

Pay special attention to the physical condition of the aquarium. If you just poured water or installed equipment, wait 2-3 hours - temperature and pH sensors must stabilize, otherwise the application may show incorrect data or not detect the device at all.

Step-by-step: how to add an aquarium to Mi Home

Follow this algorithm to avoid synchronization errors, and if you're at a certain point in time, don't interrupt it or leave the application, give the system up to 5 minutes to process it.

1. Open Mi Home and log in (if you haven’t already) and make sure you’re signed in with the same account that other Xiaomi devices are linked to.

Once the app is successfully connected, it will offer to update the firmware. Don't refuse - older versions often lack support for Russian language and automation. The update will take 5-15 minutes (the aquarium will flash blue lights).

Setting the parameters of the aquarium after connecting

When you add the device to the Mi Home, you'll open a control panel with the basic parameters.

• 🌡️ Water temperature: set your target value (optimally 24–26)°C for tropical fishes. The sensor updates the data every 10 minutes.
• 💡 Lighting: Select mode (Day, Night, Dawn/Downset) or adjust your schedule using RGB-spectrum.
• 🌀 Aeration: adjust the compressor power (20 to 100%) for a densely populated aquarium, 60-80 is recommended%.
• 🍽️ Autofeeding: Set time and portions (up to 4 feedings per day) and note that the dispenser only works with dry food of a certain fraction.

For advanced users, hidden settings are available.

1. Go to the aquarium menu at Mi Home.
2. Press three points (⋮) top-right.
3. Select “Additional options” → “Expert mode”.
4. Enter the password: 123456 (by default) or the one specified in the instructions.

In this menu, you can calibrate pH sensors and NH₃ (Ammonia) and set up critical change notifications (e.g. if the temperature exceeds 28)°C).

Compatible with other Xiaomi devices

One of the key benefits of Xiaomi’s smart aquarium is integration with other ecosystem devices, which allows you to create automated scenarios that make it easier to care for fish.

To set up automation:

1. Open Mi Home → Profile → Automation
2. Press «+» → «Add a script».
3. Select a trigger (such as “Water Temperature”) and set a condition.
4. Add an action (e.g., “Disable Smart Plug”).
5. Save the script and test it manually.

⚠️ Note: If you have multiple Xiaomi aquariums, give them different names in Mi Home (e.g. Aquarium 1 and Aquarium 2) or scenarios can run randomly, as the system does not distinguish between the same type of devices.

Solving common connection errors

Even with accurate follow-up, users often encounter problems, and here is a list of bugs and proven ways to fix them.

1. Error: "Device not supported" or "Device not supported"

The reason: the discrepancy of the region in Mi Home and the firmware of the aquarium.

Decision:

• Go to Profile → Settings → Region and change to Mainland China.
• Remove the aquarium from the list of devices (if there is one).
• Restart the app and try adding it again.

2. the aquarium is not detected in the search

Reasons:

• The aquarium is not connected to the 220V network.
• The smartphone is connected to 5 GHz Wi-Fi.
• Time network XIAOMI-AQ_ doesn't appear.

Decision:

• Reconnect to 2.4GHz Wi-Fi.
• Press Reset on the aquarium and repeat the search.
• If the network does not appear, check if the router blocks it (turn off filtering). MAC-address).

3. Sensors show incorrect data

The reason: lack of calibration or contamination of sensors.

Decision:

• Go to Additional settings → Calibration of sensors.
• For a pH sensor, use test strips for comparison.
• Clean the sensors with a soft brush (do not use alcohol!).

⚠️ Warning: If after updating the firmware, the aquarium stopped responding to commands, perform a forced reboot: disconnect from the network for 30 seconds, then turn it back on. Do not use the Reset button - this will result in a reset of all settings.

💡

If the aquarium is connected but the app is displayed in Chinese, change the language of the smartphone system to English, then return it to Russian. This often helps reset the localization cache in Mi Home.

Firmware Update: Why It’s Critical and How to Do It Right

Xiaomi’s smart aquarium firmware is not only responsible for the interface, but also for the correct operation of sensors and security, and older versions (up to 1.4.5) have been detected bugs:

• False sensor response NH₃ (ammonia).
• Lighting freeze in RGB mode.
• Loss of communication with Mi Home servers every 2-3 days.

To update the firmware:

1. Open the aquarium card in Mi Home.
2. Press three points (⋮) → «Settings of the device».
3. Select “Firmware Update” (if the item is missing, your version is up to date).
4. Confirm the load and wait until the completion (the aquarium will flash green).

If the update is hanging:

• Do not interrupt the process and do not leave the application.
• Check the stability of the Internet connection (it is better to connect to 4G if Wi-Fi is unstable).
• If after 30 minutes nothing has changed - restart the aquarium (turn off / turn on the power).

💡

Update your firmware only through a stable Internet connection. If the process is interrupted, the aquarium may stop turning on and you will need to reset through service mode (instructions in the FAQ section).
