I have a DSC Alexor PC9155 alarm system. I also have the TL265GS board which enables access over my local network. With that IP access I’m able to administer the system using the DLS software on my laptop.
I’ve been reading about how to interface HA with DSC alarm systems, and I’ve found a few options which include using an Envizalink board or an IT-100 board from DSC. But neither of those options seem to be compatible with the PC9155.
I’m confused as to why there wouldn’t be a DSC integration possible with the hardware that I already have, given that my system can already talk over my internal network, it seems to reason that it should be possible for HA to hook into that interface.
Well, integrations don’t happen by themselves. It needs someone with the dev skills that also has access to one of those devices to reverse engineer the interface if not encrypted and write code to use it on HA. Obviously, this system is not popular enough or has an encrypted interface that makes it impossible to have that happen. There is no documentation usually for those proprietery interfaces. So, you might be left to try to reverse engineer it yourself instead and post your findings and perhaps someone can jump in and assist if they can.
Fair enough. I was just trying to determine if there was a technical reason that it wasn’t possible, or if like you said, it just wasn’t a common enough system to warrant attention. I do have some general technical abilities, so I’ll have to do some googling to see how I might attempt to start reverse engineering the interface. Wireshark perhaps?
