Ok, first things first, although the smartthings app allows you to change from one LAN edge driver to another, this usually breaks because you don’t get all the security information transferred over. To use a different edge Driver for a Philips hue hub (which is an LAN device) you’ll have to scan nearby to get it to pick up the new driver. And, yes, that may mean that the hub is listed twice as a device in your smartthings app. But that won’t hurt anything.
I’m not 100% sure, but it sounds like you might be trying to use the following custom edge Driver. If so, ask in that thread for help.
