Xiaomi Honeywell Smoke Detector: How to Add to Mi Home and Avoid Mi Mistakes

Xiaomi Honeywell Smoke Detector has become one of the most sought-after smart home solutions thanks to the combination of the reliability of the Honeywell brand and the Xiaomi ecosystem. These devices not only alert smoke with a loud signal (up to 85 dB), but also integrate into the overall security system through the Mi Home app, allowing you to receive notifications to your smartphone and automate the response of other devices (for example, turning on ventilation or lighting).

In this article, we will discuss all the steps of adding a sensor from preparation to final notification settings, including unique firmware nuances for the Russian region (which the manufacturer does not always specify in the official instructions).

1. Preparation before connection: what to check

Before you start adding a sensor to the app, make sure all the preconditions are met. Errors at this stage will cause failures later, even if the device itself is in good condition.

Key requirements:

• 📱 Mi Home is 6.0.100 (for Android) or 5.12.0 (for iOS) and older versions may not support sensor connectivity.
• 🌍 The region in the application must be set to "Russia" (or "Mainland China" if you use the Chinese version of the sensor.
• 🔋 The battery charge on the sensor is at least 80%. With a low charge, the device may not respond to the requests of the application.
• 📶 Stable Internet connection on a smartphone (preferably over Wi-Fi, not mobile data) 4G/5G may be interrupted.

If the sensor is new, remove it from the package and remove the protective film from the battery compartment (it blocks contacts). Note that in some batches the film is transparent and almost invisible - check this visually. Also do not press the test button until the setting is complete, otherwise the sensor will go into self-check mode and temporarily become unavailable for connection.

2. Step-by-step instruction: how to add a sensor to the Mi Home

The process of adding does not take more 5 If you follow the algorithm without skips, the following is the current instructions for Xiaomi Honeywell Smoke Detector firmware. 2023–2026 years (models) JTYJ-GD-01LM/BW and JTYJ-GD-02LM/BW).

Step 1. Open the Mi Home app and go to Add Device (+ icon in the upper right corner). Select Security, then Smoke Sensor.

Step 2. Hold the smartphone to the sensor at a distance of no more than 10 cm and wait for the beep (one short beep).If there is no signal, press and hold the button on the sensor for 3 seconds until the blue indicator flashes.

Step 3: Connect the sensor to the Wi-Fi network:

• 🔄 Make sure your router is running in 2.4 GHz mode (the sensor does not support 5 GHz).
• 🔐 Enter the Wi-Fi password manually (copying may cause an error "Incorrect password").
• ⏳ Wait for the process to be completed (the screen will show the inscription "Device added").

Step 4: Set up notifications after successfully adding:

• ⚙️ Go to the device card and turn on the option "Smoke Notifications".
• 🔔 Select the notification method: Push notification, SMS (if the number is tied) or a call.
• 🤝 Attach the sensor to scenarios (for example, automatically turn on the hood when triggered).

3. Typical errors and their solutions

Even with accurate follow-up, users encounter errors, and here is a list of the most common problems and specific ways to fix them, proven by experience.

⚠️ Note: If the sensor shows Offline status after a successful addition, check if your router is blocking outbound connections to ports 80 and 443. ASUS with the enabled function "DDoS protection".

4. Compatible with other Xiaomi devices

Xiaomi Honeywell Smoke Detector can work not only autonomously, but also in conjunction with other devices in the ecosystem, which allows you to create a complete security system, where the sensor triggers a chain of action.

What devices are the sensor integrated with:

• 🔦 Yeelight Smart Lamps: Blinking when the sensor is triggered (set up via Mi Home Automations).

To set up the automation, go to Automation in Mi Home, select Create a script and select the smoke detector as a trigger. For example, you can create a rule: "If the smoke detector is triggered → turn on the lamp at 100% brightness + send a notification to the phone."

💡

If you have multiple smoke sensors, place them no more than 10 meters apart, allowing them to synchronize and fire simultaneously when smoke is detected anywhere in the room.

5. Firmware Update: Why It Matters

The manufacturer regularly releases firmware updates for Xiaomi Honeywell Smoke Detector, which fix connection errors, add support for new servers and improve sensor sensitivity. However, many users ignore this step, which leads to unstable operation of the device.

How to update firmware:

1. Open the sensor card in Mi Home.
2. Go to "Settings" → "Firmware update".
3. If a new version is available, click Update and wait until the process is complete (don’t interrupt the connection!).

The latest known firmware versions (as of May 2026):

• 1.4.5_0039 — False positive error corrected at high humidity.
• 1.3.8_0031 — Support for Europe servers added".
• 1.2.6_0022 — Improved compatibility with MikroTik routers.

⚠️ Warning: If the sensor has stopped responding to the test press of the button after the update, reset (10 seconds of retention) and add it again.

6. Testing and performance testing

After adding the sensor to the Mi Home, you need to check its performance, which will make sure that the device responds to smoke correctly and sends notifications.

How to test the sensor:

1. Press and hold the test button on the sensor for 1 second, a loud signal (85 dB) should sound and the red indicator should flash.
2. Check if the notification has arrived on the smartphone (in Mi Home and as a push message).
3. If the notification does not arrive, go to the sensor settings and make sure that the Notifications option is enabled.

For a full test, you can use a special aerosol to check smoke detectors (sold in security stores). Do not use open fire or cigarette smoke - this can damage the sensor!

💡

If the sensor fails to work on the test press of a button, check the battery power. At a level below 20%, the device goes into energy-saving mode and can ignore the commands.

7. Alternative ways of connecting (for experienced users)

If the standard Mi Home addition method doesn't work, alternative methods can be used, which require additional knowledge, but often help in difficult cases.

Method 1. Connect via Mi Home Lite (Light version of the application):

• Download Mi Home Lite from the official store.
• Sign in with the same account as the main app.
• Repeat the add-on process – sometimes this method works when the main application gives an error.

Method 2: Manual Addition via Token (for advanced users):

1. Get your Mi Home account Token with the Mi Token Extractor tool.
2. Use a Python script or Home Assistant app to manually add your device to your home. MAC-address.
3. Example of commands to add: python miio-cli discover --sync --token YOUR_TOKEN_HERE

⚠️ Note: Using Token violates Xiaomi’s user agreement and may result in account blocking.This method is recommended only in cases of emergency.
