Demo: Zigbee interference caused by USB 3.0
USB 3.0 can cause your Zigbee devices to fully stop functioning. In this video we show this by moving a Zigbee device and Zigbee adapter next to USB 3.0 port and cable.
The demo is done with a Home Assistant SkyConnect and IKEA Tradfri remote but this affects all Zigbee sticks and devices.
To avoid interference, use a shielded USB 2.0 extension cable and keep your Zigbee devices away from any USB 3.0 device and USB 3.0 ports.
