I currently have two zigbee Sonoff smart plugs configured in HA. However I want to add some zigbee devices away from my home, at my office. I believe 2MQTT will allow me to add/control the zigbee devices that are away from my home network? Is there a correct way to add 2MQTT, like do I need to remove my current Sonoff devices first, etc.? Any help would be great, thanks in advance!
You will need to install a Zigbee coordinator in your office and pair the office’s Zigbee devices to that coordinator.
You will obviously need a Zigbee coordinator with a network interface (as opposed to the more common USB interface).
Are your home and office networks connected by, say, a VPN?
