Hi, everyone
Yes, it is expected that you have the driver installed on your hubs despite you don’t have a Wemo device, unlike Zigbee and Z-Wave drivers, LAN drivers don’t have fingerprints, so, it wasn’t detected that you installed them at some point or not since they are not “identifiable” sort of speak.
So, it’s normal that you have it, and, as you don’t have devices using it, it won’t be running on your Hub.
