Connecting the Xiaomi fumigator to the phone: instructions for all models (2026)

Why connect the Xiaomi fumigator to a smartphone?

Xiaomi fumigators are not just mosquito control devices, they are full-fledged elements of the smart home ecosystem. Connecting them to your phone gives you remote control, automation on schedule and integration with other gadgets (such as humidity sensors or windows). But many users face problems: Mi Home app does not see the device, Zigbee protocol requires a hub, instructions in Chinese. In this article, we will analyze all the nuances from model selection to solving typical errors.

Xiaomi fumigators are made under different brands: Smartmi, Viomi, Mijia. This affects not only the design, but also the communication protocol (Wi-Fi, Bluetooth or Zigbee). For example, the popular model Smartmi Mosquito Repellent 2 works through Zigbee 3.0 and requires a Xiaomi Gateway, and the Viomi V-RMB01 connects directly over Wi-Fi. If you buy a device blind, the first step is to determine its type.

What Xiaomi fumigator models support phone connection?

Not all Xiaomi fumigators are smart. USB-Devices without a communication module (like Xiaomi Mi Portable Mosquito Repellent) are controlled only by a mechanical button:

⚠️ Note: If your model is not listed in the table, check its name on the box or in the documentation. fumigators without mentioning Smart, Wi-Fi or Zigbee probably do not support phone connection.

Also note the region of purchase: Devices for the Chinese market (with the CN suffix in the model) may require reflashing or using the Chinese version of Mi Home with a VPN. European versions (EU) are usually compatible with global servers.

Preparation for connection: what to check before starting

Before you try to connect the fumigator to your phone, follow the mandatory steps:

• 📱 Update the app: Install the latest version of Mi Home (for the first time) Zigbee/Bluetooth) or Viomi App (for Viomi) V-RMB01) from Google Play or App Store.
• 🌐 Check Wi-Fi: Xiaomi fumigators only work with 2.4GHz networks. If your router is broadcasting in the 5GHz band, create a separate network or turn on compatibility mode.
• 🔋 Charging the device: Make sure the fumigator is charged (if it is a battery model) or connected to the socket. Low charge can interrupt the pairing process.
• 📡 Location: Place the fumigator at a distance of no more than 2 meters from the phone or hub (Xiaomi Gateway) while connecting.

If you connect a Zigbee fumigator, make sure that the Xiaomi Gateway is already added to the Mi Home and is in pairing mode (flashes blue).

1. Open Mi Home → pick a hub.
2. Press... → Add the device.
3. Hold the button on the hub for 5 seconds until the indicator blinks.

💡

If you don’t have a Xiaomi Gateway but have a Xiaomi smart bulb or sensor on the Zigbee, they can be used as a “bridge” to connect the fumigator via Home Assistant.

Step-by-step: how to connect the Xiaomi fumigator to the Mi Home

Consider a universal algorithm for most models: If your fumigator uses Wi-Fi (like the Viomi V-RMB01), skip the steps associated with Zigbee.

Step 1: Adding the device to Mi Home

1. Open the Mi Home app and log in (use China mainland if you have a Chinese version of the device).

2. Press + → Add the device.

3. Select the Smart Home category → Fumigator (or enter the model name manually).

4. Follow the instructions on the screen. For Zigbee devices:

• 🔄 Press and hold the button on the fumigator for 5-10 seconds until the indicator flashes.
• 📱 Wait for the beep in the phone (means successful detection).

Step 2: Set up the network

For Wi-Fi fumigators:

1. Select your 2.4GHz network from the list.
2. Enter the Wi-Fi password.
3. Wait for the connection (the indicator on the device will stop flashing).

⚠️ Note: If the fumigator does not connect to Wi-Fi, check if the router blocks new devices (disable filtering by the device). MAC-Also try to temporarily disable the protection. WPA3 — Some Xiaomi models only work with WPA2.

Step 3: Verification of the work

After successful connection:

• 🕒 Set the timer in the device settings.
• 📊 Check the fluid level (if the model supports the sensor).
• 🔄 Create automation (for example, turn on on on a schedule or when opening a window).

Home Assistant Connection: Alternative to Mi Home

If you use Home Assistant, the fumigator can be integrated without an official app, which is relevant for users who want to avoid cloud addiction or have experienced problems in Mi Home.

Method 1: Via Zigbee2MQTT (for Zigbee devices)

1. Install Zigbee2MQTT and connect Xiaomi Gateway or another coordinator (e.g. CC2531).

2.In the configuration file configuration.yaml add:

zigbee2mqtt:


devices:




devices.yaml:




- id: 'lumi.plug.maeu01' # Replace with your fumigator ID




friendly_name: 'Xiaomi Fumigator'

3. Restart Home Assistant and check for device appearance in the interface.

Method 2: Mi Home Integration (for Wi-Fi devices)

1. In Home Assistant, go to Settings → Devices and Services.

2.Click Add Integration → Find Xiaomi Mi Home.

3. log in with the username and password from Mi Account.

4. Select a fumigator from the list of devices.

⚠️ Note: While using Home Assistant, some features (such as firmware updates) may not be available. Also note that Xiaomi periodically blocks unofficial features. API, Integration may require an update.

💡

Home Assistant allows you to bypass the limitations of Mi Home (e.g. region-specific) and create complex automation, but requires technical skills.

Common mistakes and their solutions

Even with the right connection, users face problems, and here are the most common ones and ways to fix them:

If your Viomi V-RMB01 fumigator is permanently losing touch, try:

1. Disable the energy-saving mode on the router for this device.
2. Set up static IP-router.
3. Update the firmware through the Viomi App (if available).

Critical information: Xiaomi's Zigbee fumigators (like Smartmi Mosquito Repellent 2) don't work with third-party hubs (like Philips Hue or Samsung SmartThings) because of Xiaomi's proprietary protocol.Use only the original Xiaomi Gateway.

Automation and Useful Scenarios

And by connecting the fumigator to your phone, you can create smart scenarios. Here are some ideas:

• ⏰ Schedule: Turn on the device 30 minutes before bedtime and turn off after 4 hours.
• 🌡️ Weather: Activate the fumigator if the temperature is higher +20°C (via integration with Xiaomi Temperature Sensor).
• 🚪 By window sensor: Turn on when opening window (required by Xiaomi) Door/Window Sensor).

Home Assistant Automation is being configured through YAML-configuration or visual editor Node-RED. Example of code to enable a fumigator when opening a window:

automation:


- alias: 'Fumigator with open window'




trigger:




platform: state




entity_id: binary_sensor.window_contact




to: 'on'




action:




service: switch.turn_on




entity_id: switch.xiaomi_fumigator
