Sharing my solution for a panel that won’t accept commands. I wanted to be able to arm and disarm the panel and trigger the alarm. After going through a few ideas on another forum I was pointed to this:
So if like me you have zone 8 spare then you can use this to achieve what i wanted. I constructed this:
I 3D printed a simple box with external dimensions of 94x54x29mm (I used 2mm wall thickness and also a 2mm thick lid made the total height 31mm) to house it and that fits perfectly to the left of the battery. Running ESPHOME on the D1 mini with this config:

I have two switches which I can use to dis/arm the panel and trigger the alarm. I am using ha-floorplan to build my own alarm control panel. This is where I am currently at (The disarmed on the left is the NESS panel and on the right is the HA automations):
