Hi ,

My suggestion , if you haven’t already, is to use the long name for the stick. Not the usb port string.

Then as things reboot and the actual port changes in the back-end, the correct device will be addressed.

Mine looks like this:

/dev/serial/by-id/usb-ITead_Sonoff_Zigbee_3.0_USB_Dongle_Plus_0883963e9ec8abc123456c5c3de5b81b4-if00-port0

Have you looked into the baud rate and checked that 115200 is the correct one?
