Honeywell Tuxedo API

Hi there, I have a Honeywell Tuxedo and the only thing I want is to make entities to see if the alarm is on or off.
I tried google search the internet but everthing I found didn’t work. Is it even possible ?
Is there someone who can help me ?

What security system is this hooked up to? If it’s a vista 15/20p, you can use various interfaces (envisalink,ad2p, diy) to talk to the alarm system directly if all you are concerned about is the alarm status itself.

The security system is a vista 21IP

The vista 21p can also be interfaced to homeassistant the same as a Vista 20p using the interfaces I mentioned.
