Local integration with Honeywell/Resideo Lynx 5xxx?

Hi. In short, I want to know if there is an existing solution to integrate locally HA with my Honeywell/Resideo Lynx 5200 (L5200) Touch Panel alarm system.

We are in a new house that was already equipped with this alarm system monitoring a set of door, motion and smoke sensors (no branding on sensors but documentation says they must be 345 MHz). We don’t have any plans at the moment to subscribe to a central alarm monitoring service.

I would like to leverage the existing set of Honeywell sensors from HA instead of duplicating sensors.

I saw that there is a Total Connect integration with the Resideo Total Connect 2 cloud solution, but to my understanding this requires subscription to a monitoring service.

Is there a local integration available for this?

If not, anyone knows if there is another control panel I can use in place of the L5200 that would support local integration with HA and would also support existing sensors?

If not, any solution to integrate directly the sensors into HA?

Any hints/references would be appreciated.

Thanks for your help.
