A few months ago I had a dimmer that I almost never use above the kitchen sink just stop working. After everything I tried I ended up replacing it. Today I found my outside front porch light was on. When I tried to turn it off at the switch I couldn't. I grabbed my IPad and turned it off with the control page but couldn't turn it back on with the switch. It appears to only work with the control page.
I then tried to resync the device and got the below error again just like the dimmer.

What is causing this and do I have to replace another switch or is there a fix?
UPDATE: After checking several other devices it appears no matter what device I try to resync I am getting the same above error. But that doesn't still explain why I can't turn the light on at the switch but its still functional in control page
