All the same problems that I’ve seen everyone else writing about that their XFI basically doesn’t work you can’t do it it was built to do which is to control your kids activities or other devices on your home Wi-Fi. When are you going to come up with some answers?
I (think) I had some issues with this a few months ago. It seemed like it worked then it wouldn't. But it did start working correctly. Both pausing a device as well as the sleep mode pausing the device. Good luck.
