@user3340 I quickly read this thread and don't believe you ever answered @brad5's question about how your AD2Serial alarm decoder connects to your Vera. Alarm Decoder makes several products and many of us have them integrated with HE but this depends on how it connects. I have an old AD2Pi "hat" that is connected via Arduino and then to HE. Alarm Decoder also has a "network appliance" that is basically the AD2Pi hat on top of a RPi and it uses Wifi to communicate to HE and there is a community driver for that.
There is a community driver for this, though no longer maintained by the developer. I ended up ditching that integration and went completely local via this button and a dry contact relay:
Here is a long thread discussing local options for MyQ
