How to Manage Xiaomi Smart Aquarium: From Customization to Automation

Xiaomi’s smart aquariums are not just a decorative element of the interior, but a full-fledged ecosystem with automated control of water parameters, lighting and feeding fish. Unlike traditional aquariums, the brand’s devices (for example, Mi Smart Fish Tank or Xiaomi Aquarium Lite) are integrated into the Mi Home app, allowing you to control them from a smartphone, voice or through smart home scenarios. But how to properly set up such an aquarium, avoid typical mistakes and automate pet care as much as possible?

In this article, we will look at all the steps from first connection to fine-tuning parameters, consider compatibility with other Xiaomi devices (for example, Mijia temperature sensors or Aqara smart sockets), and give practical tips for solving common problems. We will focus on automation: how to adjust the feeding schedule, control the pH of water or synchronize lighting with fish biorhythms. If you are just planning to buy or have already encountered difficulties in operation, here you will find answers to key questions.

What Xiaomi Smart Aquarium Models Are and How They Differ

Today, Xiaomi and its Mijia ecosystem are producing several models of smart aquariums, which differ in functionality, volume and degree of automation.

• 🐟 Mi Smart Fish Tank (30L) — base model with automatic feeding, LED-It's a light and temperature sensor, suitable for beginner aquarists.
• 🌊 Xiaomi Aquarium Lite (20L) — compact version with a focus on design and minimalistic control through the application.
• 🔄 Mijia Smart Aquarium Pro (50L+) — Advanced version with support for external sensors (pH, water hardness), advanced scenarios and compatibility with Xiaomi Home Assistant.

The key difference is the degree of automation. For example, the Mi Smart Fish Tank requires manual feeding schedules, while the Mijia Pro can adjust water parameters on its own based on external sensors. It is also important to consider compatibility with other devices: some aquariums work only through the Mi Home, and advanced models support integration with Apple HomeKit or Google Assistant.

When choosing a model, focus on:

• 📏 Volume of the aquarium (from 20 to 100)+ litres – affects the number of fish and the complexity of the ecosystem.
• 📱 Level of automation – whether pH, ammonia sensors are needed or whether temperature control is sufficient.
• 🔌 Compatibility – check if the model supports your smart devices (e.g. Aqara sockets for filter control).

First Connection: How to Set Up Xiaomi Aquarium with Mi Home

The process of setting up a smart aquarium begins with connecting to the Mi Home app. Important: before you start, make sure that your smartphone is connected to a 2.4 Hz Wi-Fi network - Xiaomi aquariums do not support 5 Hz.

1. Download and install the Mi Home app (available for Android and iOS).
2. Sign up or sign in to your Xiaomi account (be sure to link your phone number to restore access).
3. Connect the aquarium to the power supply network and wait until the indicator on the body begins to flash blue (conjugation mode).
4. In the app, click Add Device (+) → Aquariums → Choose your model.
5. Follow the instructions on the screen: confirm the flashing indicator, select the Wi-Fi network and enter the password.

Once successfully connected, the aquarium will appear in the main menu of Mi Home.

• 🔹 Set up a feeding schedule (time, portions).
• 🔹 Control water temperature (in advanced models – pH and rigidity).
• 🔹 Manage LED-backlighting (brightness, color temperature, scenarios).

💡

If the aquarium is not connected to Wi-Fi, try restarting the router or temporarily disabling network protection (for example, filtering). MAC-address).

An important nuance: the aquarium may require a firmware update when it first connects. Do not interrupt the process, this can cause sensors to fail. Average refresh time: 5-10 minutes. If the device does not respond after the update, reset (press the power button for 10 seconds).

Setting water parameters: temperature, pH and filtration

Water quality control is the foundation of fish health. Xiaomi's smart aquariums allow for automation, but require the right initial setup.

To fine-tune the parameters:

1. Use external tests (such as drip tests) API or JBL) To check the readings of the sensors of the aquarium, the discrepancy of more than 10% suggests the need for calibration.
2. The Mijia Pro model offers automatic adjustment: if the pH or temperature is deflected, the aquarium can turn on the heater or liquid dispenser (if connected).
3. Use compatible cartridges (e.g. Xiaomi Mijia Filter Cartridge) to filter, and replace them every 4-6 weeks.

Critical information: if the temperature sensor shows a value below 18°C or higher than 30°C, the aquarium will automatically turn off the heater to avoid overheating or hypothermia, in which case check the equipment and the location of the aquarium (away from direct sunlight or air conditioning).

Feeding automation: schedule, portions and compatible feeds

One of the key functions of smart aquariums is automatic feeding, which not only saves time, but also prevents overfeeding of fish, which often leads to water pollution.

• ⏰ Schedule: up to 5 feedings per day with an interval of at least 2 hours.
• 🍽️ Portions: adjustment of feed volume (from 1 before 10 units 1 ≈ 0.1 gram).
• 🔄 Manual mode: one-time delivery of food on request from the application.

Adjustment recommendations:

• For most fish species, 2-3 feedings per day (morning, afternoon, evening) are sufficient.
• Start with a minimum serving (2-3 units) and see if the food is eaten completely within 2-3 minutes.
• Use compatible feeds: pellets with a diameter of no more than 1-2 mm (for example, TetraMin or JBL NovoBel. -- Large flakes can clog the dispenser.

The Mijia Pro models have a Smart Feed feature that analyzes fish activity through the camera (if connected) and adjusts portions, for example, if fish swim slowly to the feeder, the system can increase the amount of feed.

⚠️ Warning: If you are away for a long time, don’t rely on automatic feeding alone. Check the food supply in the bunker (usually lasts 7-10 days) and set up backup food for the aquarium (e.g. Xiaomi Mi Power Bank with 12V adapter).

Lighting control: scenarios, color temperature and biorhythms of fish

Lighting in an aquarium affects not only aesthetics, but also the health of fish and plants. Xiaomi’s smart aquariums allow you to adjust color temperature (from warm to warm). 2700K coldly 6500K), brightness and on/off schedule. Key recommendations:

• 🌅 Dawn/Downset Simulation: Smooth change in brightness over 30–60 minutes in the morning and evening reduces stress in fish.
• 🌿 For plants: use the spectrum of 5000–6500K (cold white) and light day duration 8-10 hours.
• 🐠 For fish: warm light (2700–4000K) and reduced daylight hours (6-8 hours) for species that prefer dimmed lighting (e.g. scalars).

Setting up the lighting in Mi Home:

1. Go to the Device. → Lighting.
2. Choose manual, schedule or "Natural cycle" (automatic simulation of day/night).
3. For advanced scenarios, use a smart home → Automation where lighting can be linked to other devices (e.g., turning off lights when a motion sensor is activated in a room).

Unique feature: in the model Mijia Smart Aquarium Pro available mode "Moonlight" - weak blue lighting (1-2 lux), which does not prevent fish to rest, but allows you to watch them at night through the camera.

💡

It is critical for fish to maintain a day/night cycle, and constant lighting can lead to stress, loss of coloration, and shortened lifespan.

Integration with a smart home: scripts, voice control and compatibility

Xiaomi’s smart aquariums can be integrated into the smart home ecosystem by creating complex scenarios.

• 🔊 Voice control: via Alice (Yandex), Google Assistant or Siri (for models with HomeKit support). Team example: Alice, turn on the aquarium light at 50%".
• 🔄 Automation: Turn off aquarium lights when you leave the house (by geolocation); turn on the filter to maximum power when ammonia levels rise (if an external sensor is connected).
• 📊 Monitoring: displaying water temperature data on the screen of the Mi Band or Amazfit smartwatch.

To customize the scenarios:

1. Open Mi Home and go to the Smart Home section → Automation → Create a script.
2. Select a trigger (e.g., time, geolocation, sensor data).
3. Add an action (for example, turn on feeding or change the color of the lighting).
4. Save the script and test it out.

⚠️ Note: When creating scenarios with external devices (such as smart sockets to control the compressor), make sure that all gadgets are connected to the same region in Mi Home (China, Europe, Russia.

Typical problems and their solution: from connection errors to equipment breakdowns

Even with smart aquariums, users face challenges, and consider the most common problems and ways to fix them:

If the problem is not solved by standard methods:

• 🔧 Reset the aquarium settings (press the power button for 10-15 seconds before resetting the indicator).
• 📞 Contact Xiaomi via the Mi Home app (Profile) → Support → Online chat).
• 🛠️ Check warranty: Most models have a 12-month warranty (check and device serial number required).

⚠️ Note: if after updating the firmware aquarium stopped responding to commands, try rolling back the version of the software:

1. Download the old firmware from the official Xiaomi website (section "Files for developers").
2. Connect the aquarium to the PC via USB-Type C (in debugging-enabled models).
3. Use the MiFlash utility for firmware in manual mode.
