Our security system went offline. I had to let a neighbour into house to pull plug and reboot security system. Came back on-line after reboot. Security system should have a built-in reboot when it detects that it has been off-line for say 1/2 hour. A dead security system is no security. My other option is to plug security system into Wyze plug and force a reboot.
