@mgejke I just tried to run the Sector app on my phone at it could not get status from my central at home so I quickly gathered that this was not a HA issue but an issue with the alarm system itself. When I called Sector I complained about their app, no info about HA at all Good secrets are best kept well hidden imho
The stated that my central was “offline”. Whatever that means. The central is GSM based. What they did I do not know but suddenly it worked again. The probably booted it or something similar.
Mains and mainsrestore might be if the central looses power from the mains in the house. I know that the system puts out alarms on both loosing power, low battery on devices and more. This data is relayed to Sector and not to the user/app or similar. Not sure if the log entries you see could be related?
