I have an AD2USB installed for my Honeywell Vista-128BPT (Vista’s high capacity polling loop alarm system) at my home and it works great with Home Assistant - with exception to the Arm Night mode. The Arm Night Mode feature for AlarmDecoder in Home Assistant is programmed for the Vista low capacity panels - GitHub - ajschmidt8/adext: An extended AlarmDecoder for HomeAssistant, which is code+7. However, the Vista-128BPT/250BPT high capacity polling loop alarm needs code+71. This addition for Vista’s high capacity panels would be greatly appreciated.
IMO you’re probably better off opening a github issue on the adext library. The authors are much more likely to see it and respond.
