New Homekit Outlet issues

I was trying to add a Meross outdoor smart switch into Homekit and it never worked until I unplugged the Firewalla. I checked the Quarantine and moved it from that group after the first attempt and then set it to no group. Is there a setting that I am missing? To get it to work, I unplugged the Firewalla and tried again, it worked immediately.  Anyone else having this issue?
