I got the -E version & installed the Zigbee binding “Ember Coordinator”.
Status: INITIALIZING
Started searching & found [SOLVED] How to setup the Sonoff Zigbee USB Dongle? - #21 by Maximo
But “solution”: “usermod -a -G lock openhab” produces error: “usermod: group ‘lock’ does not exist”
and I’m not even sure I’m on the right track.
