Setup help

Hi

I am trying to setup this feature in HA but I am quite a noob with HA and I can’t make it work after serval tries.

The setup instructions mentions only one serial device, would this include a sonoff Zigbee dongle too?

I say this because once I had started the sunsynk add on the zigbee2mqtt add on would not start and reported errors

If so how would I set it up with both usb devices connected?

Other devices should not be an issue

Multiple addons/programs will not work if they both try to use/open the same USB device

so 1 app/addon to 1 usb device and you should be ok
