Unlike previous versions (for example, Gateway 2), the third model lost the built-in speaker and the new model is not available. RGB-It has been backlit, but has improved processor, Matter support (through updates) and an expanded list of compatible devices, but many users have trouble adding older sensors or devices from third-party brands. Next β analysis by category, instructions and solutions of typical errors.
1. Official list of compatible devices from Xiaomi and Aqara
Xiaomi Gateway 3primarily It works with devices based on ZigBee 3.0, but some gadgets connect via Bluetooth Mesh (for example, some Yeelight lamps), officially supported devices with the logos Xiaomi, Aqara and Mijia released after 2019 (earlier models may not be recognized). Below is the current list for 2026, confirmed by the manufacturer.

Important: devices marked βZigBee 1.2β (such as the old Xiaomi Mi Home Sensor Set sensors) are not compatible with Gateway 3. The gateway also does not support Wi-Fi-based devices (such as Xiaomi Mi Smart Socket Wi-Fi) β they need a separate hub or direct access to the router.
2. How to check the compatibility of the device before buying
Before buying a new sensor or lamp for Xiaomi Gateway 3, check two key parameters:
- Communication protocol: Look for ZigBee 3.0 or Bluetooth Mesh on the box or in specs. Devices with ZigBee 1.2 or Wi-Fi won't work.
- Compatibility logo: Look for Mi Home, Aqara Home or Mijia icons. Devices from third-party brands (like Philips Hue) require additional customization.
Methods of verification:
- π Official website: The product page in the Mi Store or Aqara should have a "Compatibility" section mentioning Gateway 3.
- π¦ Device box: The back side usually has a list of supported hubs.Look for the model ZNDMWG03LM.
- π Database: Use services like Zigbee Device Compatibility where users share their experience.
π‘
If the device box says "Works with Mi Home" but does not specify the protocol, write in support of Xiaomi with a request to clarify the version of ZigBee. Often sellers confuse models!
Step-by-step: how to connect the device to Gateway 3
The process of adding the device to the Mi Home ecosystem takes 2-5 minutes, but requires precise follow-up instructions, and here is the universal algorithm for most sensors and lamps.
Make sure Gateway 3 is connected to power and internet (lights blue)
Update the Mi Home app to the latest version (in the App) Store/Google Play)
Remove the device from other hubs (if it has already been paired)
Place the device at a distance of no more than 10 meters from the gateway (no obstacles)-->
Connection steps:
- Open the Mi Home app, go to the Smart Home section" β "Add the device".
- Select the category of the device (e.g., "Sensors" β "Door opening sensor").
- Follow the on-screen instructions: You usually need to press a button on your device (e.g. hold 5 seconds) or scan. QR-code.
- Wait for the process to be completed (the indicator on the device should flash green or blue).
- Assign the device a room and a name (for example, "Flight Door Sensor").
If the device is not located:
- π Check the battery charge (sensors are often used) CR2032 β it may be discharged).
- πΆ Move Gateway 3 closer to the device (walls and metal objects block ZigBee signal).
- π Reboot the gateway (turn off power for 10 seconds).
What if the device connects but appears as βOfflineβ?
4. Compatibility table: Xiaomi Gateway 3 vs Gateway 2
Many users are wondering if it is possible to use older devices from Gateway 2 with a new version of the gateway. Below is a comparison table of compatibility of key devices.
| The device | Gateway 2 (ZNDMWG02LM) | Gateway 3 (ZNDMWG03LM) | Notes |
|---|---|---|---|
| Xiaomi Mi Door/Window Sensor (1-I'm a version) | β Yes. | β No. | ZigBee 1.2 is not supported |
| Aqara Door/Window Sensor 2 | β Yes. | β Yes. | ZigBee 3.0 β Full Compatibility |
| Xiaomi Mi Motion Sensor (Version 1) | β Yes. | β No. | Requires firmware updates (not always working) |
| Aqara Smart Plug | β Yes. | β Yes. | Supported, but may require manual addition |
| Yeelight LED Bulb (Wi-Fi) | β No. | β No. | Requires Wi-Fi connection, does not work via ZigBee |
Critical note: if you upgrade the ecosystem from Gateway 2 to Gateway 3, be prepared to replace some of the older sensors.The manufacturer does not guarantee backward compatibility, and some devices may not work well even after a successful connection.
5. Connecting devices of third-party brands (IKEA, Philips Hue, Tuya)
Xiaomi Gateway 3 theoretically supports devices from other brands running on ZigBee 3.0, but in practice this requires additional manipulation.
5.1. Lamps IKEA Tradfri
Lamps IKEA Tradfri (e.g., Tradfri, E27 1000lm) You can connect to Gateway 3, but only through an intermediate hub (such as Sonoff ZBBridge) or using Tasmota firmware.
5.2 Philips Hue devices
Integration of Philips Hue lamps requires:
- Connect them to the original Hue Bridge hub.
- Use Home Assistant or Node-RED to link to Mi Home.
- Set up automation through IFTTT or Yandex Alice.
5.3 Tuya ZigBee sensors
Some Tuya sensors (such as the Tuya Door Sensor) can be added to the Mi Home, but:
- π§ Reset the device to factory settings (hold the 15 second button).
- π± Use alternative software, for example, Zigbee2MQTT.
- β οΈ Functionality may be limited (for example, notifications will not work).
π‘
Third-party devices rarely work consistently with Xiaomi Gateway 3. For reliable integration, it is better to use universal hubs like Home Assistant or other devices. Zigbee2MQTT.
6. Frequent errors and how to fix them
Even with officially supported devices, users are facing problems. Consider typical scenarios and solutions.

The device is not in addition
Causes and solutions:
- π‘ Weak signal: Move Gateway 3 closer to your device or use a ZigBee repetitor (e.g., Aqara Smart Plug).
- π Replace the battery (even if the device is new β batteries can self-discharge when stored).
- π Conflict with other hubs: Disable other ZigBee devices (e.g. Amazon Echo or Samsung SmartThings).
6.2 The device connects but does not send data
A frequent problem with motion sensors or door openings.
- π΅ Power saving mode: in Mi Home settings, turn off the option "Battery Saving" for the device.
- π Firmware Update: Go to Device Settings β Update of the PO.
- π‘ Interference: If you have a microwave or Wi-Fi router nearby at 2.4 GHz, try changing the ZigBee channel in the gateway settings.
6.3 Gateway 3 does not respond to commands
If the gateway itself becomes inaccessible:
- Reboot it (turn off power for 30 seconds).
- Check your internet connection (the indicator should be blue, not red).
- Update the firmware through Settings β Update of the software (up-to-date version at the time of writing the article β 1.5.6_0039).
- Reset the gateway to factory settings (the reset button is on the bottom panel - hold for 10 seconds).
7. Alternative ways to control devices
If the Xiaomi Gateway 3 doesnβt support the device you want, consider alternative smart home integration options.
7.1 Use of Home Assistant
Home Assistant is an open-source smart home management platform that supports hundreds of devices, including those that are not compatible with Mi Home.

miio:
devices:
- host: 192.168.1.100 # IP- Gateway 3
token: YOUR_TOKEN_HERE
model: zhimi.gateway.acn017.2. Zigbee2MQTT
Zigbee2MQTT β This is a software for managing ZigBee devices through MQTT-broker, advantages:
- π§ Support for devices that are not compatible with Mi Home.
- π Advanced settings and logging.
- π The ability to install devices (for example, for IKEA Tradfri).
You will need a Raspberry Pi or other computer with ZigBee support to set up (for example, a ZigBee adapter, CC2531).
7.3 Cloud services (IFTTT, Yandex Alice, Google Home)
If you need integration with voice assistants or other platforms:
- π€ Yandex Alice: Connect Mi Home with Xiaomi Smart Home Skill".
- π IFTTT: Create applets for automation (for example, "If the motion sensor is triggered, turn on the lights").
