Thank you for the clarification. Now I understand your frustration. Sorry to hear about the Asus 3100 giving you grief. I am using an Asus RT-AC86U as my main router, with a Cat5-connected Asus RT-AC66U as an Access Point on the other side of the house. I am running AsusWRT-Merlin firmware on both devices.
I am using the ported SmartThings App and Drivers found in the following post. I just haven't had a need to try adding my second Harmony Hub to Hubitat yet. I just love the Harmony Hub's performance as a remote control for an extra room in the house.
EDIT: Glad to hear you figured it out!
