There is some discussion in the firmware discord channel about getting this feature added and it isn't certain the firmware will allow for multiple connections. Fingers are crossed for it to be included as its been requested by multiple people here. You may not see the feature being available for a few weeks to a month though.

At this time its not possible to connect two devices to the same WebUI. We may revisit this at a later time but for now its a limitation of the WebUI.
