Linear delta 3 reciever

I have a gate that opens outside my house. It uses a Linear Delta 3 Gate receiver to send a command to the Door King to open and close. Since hooking up my Smart Things Hub and motion sensors, the gate will open only once in a while. I have tried all four remotes that should work with the Delta 3 receiver. Sometimes the gate will open when I hit the remote button but most of the time nothing happens. I am wondering if the Smart Hub is blocking the Delta 3 signal. When I turn off the Hub the gate operates fine.

Anyone else have this problem? Any solutions to this? I would love to throw the gate on the Hub so I could open it with my phone but I have not found anything to do that with. I found the garage door openers that work with Smart Hub but not a gate opener.
