Similar problem with the hkc I assume you mean at night efault comes up loss of Wi-Fi, common with hkc Wi-Fi cards as well, you can turn off the audible notification that you have lost Comms on the panel itself you would still get the notification on the app that you have lost comms with the panel when you're out not sure what you mean DD about using home plugs he would have to change the Wi-Fi card and use a network card of sorts
