I just got a Harmony 890 with RF Extender to control devices inside of a cabinet. However, it doesn't work. I've tried every suggestion I could find online, no go. The RF Extender only receives maybe 1 out of every 20 commands.
Then I brought my Extender and my Remote into the garage. It works fine. The extender receives commands from many feet away even with a car blocking line-of-sight.
I brought it back inside, tried every room, every outlet, turned off every light, every appliance/electronic device... nothing. What could be interfering with the device inside my home and how might I find out?
This is a brand new home, foam filled exterior walls.
On the same note, I can barely get WiFi to function in the house.
Any help is appreciated.
