Outlets not powering off/on in Home
### Expected Behavior
I expected the outlets to turn off and on, as they were showing correctly in the Home app. I added them via their MAC addresses, which worked. One HS100 (inside) and two KP400 (outside)

### Current Behavior
When trying to turn off or on in Home, they do nothing.

### Steps to Reproduce (for bugs)
Unsure.

### Versions
<!-- Please run commands and include versions below. -->
Node.js: 16.13.1
