Xiaomi has introduced several inexpensive home automation products over the years, often under their Mijia brands with for example a WiFi to IR blaster, a Zigbee & WiFi smart home kit, a smart door lock, or a smart speaker among other products.
Recently, the company has launched the Xiaomi Smart Multi-mode Gateway that supports Zigbee 3.0, WiFi, Bluetooth, and Bluetooth Mesh.
Xiaomi Mijia Smart Multi-mode Gateway (model ZNDMWG03LM) key features and specifications:
- ZigBee2.0 / ZigBee3.0
- 2.4GHz Wi-Fi 2×2 MIMO
- Bluetooth & Bluetooth Mesh
- Compatible with Apple Homekit
- Max range – 200 meters (Line-of-Sight)
- Up to 32 devices
- Power Supply – 5V/1A
- Dimensions – 90x25mm
- Temperature Range – -5℃-50℃
- Humidity – 0%-95%RH, non-condensing
The gateway can be controlled via Mi Home app running on Android 5.0 or iOS 12.0 smartphones. It’s compatible with Apple Homekit, Xiaomi Mi AI speaker, and the earlier Zigbee/WiFi kit with Aqara gateway and Zigbee sensors and sockets.
I initially thought it might an ESP32 + Zigbee design based on the description, but since WiFi 2×2 MIMO is supported it has to be another solution, and I have yet to see any teardowns.
