Complete noob wondering about alarm systems?

Hardware

Hi, I’ve literally just setup my home assistant half an hour ago. All working fine, most of it self explanatory. I just saw something AlarmDecoder and it got me wondering about my alarm system (Honeywell Wireless Alarm Kit HS311S). It has no smart capabilities and is just handled by a wireless keypad & fob, and I very much doubt I can do anything smart with it but just thought I’d ask.

Thanks!

I’ve been using an AlarmDecoder since first installing Home Assistant some years ago. It’s been very reliable.

I may have already sent you a message, but I’m looking for answers. My AlarmDecoder works fine when it’s connected to a PC - Arms/Disarms.

When connected to HA, it won’t Arm/Disarm with HA’s keypad interface. I’ve tried typing in the code and clicking Home or Away. I’ve tried clicking the numbers and clicking Home or Away. I’ve tried typing in the code and ‘3’ for ‘stay’. All with no response from the Vista 21ipLTE.

I’ve confirmed it’s set to CON ADR 18 (and it functions using the PC App when connected to my laptop.

It shows the arm state and all sensors work in HA - Vista motion detectors trigger lights, Vista trip creates an alarm.

Thanks in advance.
