Not works on old Zigbee2MQTT version such as 1.24.0, tested works on Zigbee2MQTT 1.28.4.
Due to a bug in Zigbee2MQTT, all the 5 sockets (inc. USB) turn on/off together, also ZigBee interview is not successfully. See https://github.com/Koenkk/zigbee2mqtt/issues/12442.
Note: After upgrade Zigbee2Mqtt, you may need to remove the device and add it again.

Issues: the USB output is not properly designed, it causes RCD tripped in my use case. The viewsonic projector is connected to first socket and connected to a Google TV. As long as the Google TV USB power cable connected to the USB power port, it trips the RCD. This indicates the USB power is not properly designed, it is likely provide the current leakage path between earth to Neutral/Line and tripped the RCD protector. There is a small chance something wrong with my Viewsonic X10-4K projector or Google TV design, and caused the RCD tripped. The real reason is unclear to me.
