Cox Homelife Repurpose


I’m new to the HA community and am starting with the HA Green. I have an existing Cox Homelife security system. I am leaving Cox and was wondering if anyone had luck using their devices. I am trying to save some cash as they are less than 2 years old and all work fine. The equipment is listed below and am just wondering if this is an exercise in futility before I get too deep. Appreciate any insight, thanks.

-Sercomm SZ-DWS08N-CZ3 door/window sensor
-Sercomm Icamera2
-Visonic GB-540 Glass break detector
-Visonic MP-841 motion detector
-SMC CO 02-Z Carbon Monoxide Alarm
-Sercomm SZ-WTD03 water detection
