Hello everyone,
I’m new to the Home Assistant community and I’m struggling with the setup.
I’m trying to run MQTT and Zigbee2MQTT on a Raspberry Pi 4 with a Zigbee 3.0 USB Dongle Plus (Dongle-E).
My main issue occurs when I try to start Zigbee2MQTT. Here are my logs 
[21:40:10] INFO: Preparing to start...
[21:40:10] INFO: Socat not enabled
[21:40:11] INFO: Starting Zigbee2MQTT...

And here is my Zigbee2MQTT configuration:

options: "-d -d"
log: false

adapter: ember
I’m really running in circles at this point. I’ve heard about recent compatibility issues, but I don’t know enough yet to draw any conclusions.
Could someone please help me figure this out?
Thank you all!
