Best Xiaomi Mijia Smart Multi-Mode Gateway 3 (ZNDMWG03LM) Zigbee 3 and BLE review


Before we start to discuss the Xiaomi Mijia Smart Multi-Mode Gateway 3 (ZNDMWG03LM), let’s first briefly talk about what made the previous versions special. First, the most obvious thing: the Xiaomi gateway started a Zigbee revolution. A few reasons for the the popularity:

  • Xiaomi was one of the first that offered a whole range of Zigbee devices that were compatible with their own gateway.
  • All Xiaomi products are very affordable, well designed and good looking.
  • Most of the products were and are compatible with projects as zigbee2mqtt.
  • Xiaomi Gateway 2 (DGNWG02LM, lumi.gateway.v3)* has a “developer mode” on board, which opens a local access protocol to control Zigbee devices of this gateway. There are integrations of this protocol in many open source smart home systems, for example Domoticz and Home Assistant.

The first gateway only supported the Zigbee protocol. In this article we talk about the Xiaomi Mijia Smart Multi-Mode Gateway 3 (ZNDMWG03LM). This gateway supports Zigbee 3Bluetooth Mesh and HomeKit. However, it is still offered at a affordable price. Let’s find out the differences with the previous versions and if it’s worth the money for upgrading or buying it as your first gateway.

*The Euro version of this Xiaomi Gateway EU (DGNWG05LM, lumi.gateway.mieu01), as well as the updated version of Xiaomi Gateway 3 (ZNDMWG03LM, lumi.gateway.mgl03) does not have this protocol.


Gateway version 3

The updated version of the gateway has a new chip with Zigbee 3 (EFR32MG1B), as well as support for Bluetooth Mesh and HomeKit technology. Not all devices are supported in HomeKit yet. But there is a solution to add all kind of third party Zigbee devices through a Home Assistant plugin that is in development.

Xiaomi Gateway 3 software

This gateway is still compatible with the Mi Home app and can be added even if you already have an (first edition) gateway.

Xiaomi Gateway 3 (ZNDMWG03LM) compatible with Home Assistant

But we from gadget-freakz are more interested in the possibilities to integrate Xiaomi Gateway 3 (ZNDMWG03LM, lumi.gateway.mgl03) into our own favorite platform: Home Assistant. Integration of the old gateways was easy: retrieve Mi Home token, add IP of gateway and enter the token. This newer gateway works different. You still can retrieve your token.
But it will not be added automatically added in Home Assistant. Therefor you need an custom component.

Is the ZNDMWG03LM Worth your money?

First of all, it’s affordable with an price around 20~25 euro at Banggood. If you are not a tech savvy person and want something that works out of the box with the compatible of most of the Xiaomi devices, buy it! When having lots of different Zigbee brands and devices, you can take a look at the custom component to get those items working (no warranties all devices will be working). But if you want to be sure almost every Zigbee device will work, and you prefer Home Assistant it’s worth checking the Zigbee2mqtt method with one of the products below:

Where to buy?

  • Design
  • Quality
  • Usability
  • Home-Automation compatibility
  • Price


The new Xiaomi Gateway 3 is a nice product for a affordable price. The fact that is has bluetooth mesh and the newest Zigbee 3 make it a future proof device. Also the Homekit functionality can come in hand for the Apple lovers. But not all the devices the older models support are (yet) supported. There is no roadmap available with plans for adding devices is the near feature, so check which devices you already have or want and if they are compatible.  Another thing is that is comes with the option to open a telnet session, this is nice for development and as we speak it’s already possible to integrate this Gateway into Home Assistant and retrieve Zigbee and Bluetooth devices that are paired with the gateway.
