Sonoff Dongle E alongside Sonoff Zigbee Bridge Pro Hub

Hi,

I have the Sonoff Dongle E running on my HAOS setup with Z2M. I’m planning on running a Sonoff Zigbee Bridge Pro Hub at my partners property with a few devices, then connecting it to my HAOS via a site-to-site VPN (She doesn’t want to run a HAOS machine at her property)

What will be the easist way to integrate the sensors from the SONOFF Zigbee Bridge Pro Hub at her property into my HA?

You can use another instance of Z2M or ZHA.
