I’ve put together a Component for the Visonic Powermax / Powermaster Alarm Systems. It doesn’t do everything at the moment so please be gentle with me as it’s my first adventure in to Home Assistant python.
You’ll find it here
Installation is simple, download a zipped version from Github and unzip it in to your custom_components directory. If you don’t already have a custom_components directory then create one in your config directory (where your configuration.yaml file is).
You’ll need to put some stuff in to your configuration.yaml file too, see the example I put in the description on github. You’ll also need a physical connection to the panel itself remember.
Have fun and I’m sure you’ll let me have some feedback
