I have aquired a second Hue bridge in order to spread the load a little. I can’t figure out how to move lights and rooms to the new bridge, though?
Do I have to delete a room from the first bridge and then set everything up on the second bridge or is there a simple was to just transfer a room (settings, schedules and all) to the second bridge?
The easiest way to move lights is to first delete them on the old bridge. That will reset the light. Then you can just do a search for lights on the second bridge and it should be found automatically.
If the light is not found, check out the following: How to connect Philips Hue lights to a Philips Hue bridge?
You would need to create your rooms and schedules again on the new bridge. There is currently no way to migrate those settings.
How is deleting and re-adding the easiest way? I think the Op was trying to avoid that
