AD2Pi (Serial) + Home Assistant Problems

I'm running the AD2Pi with Home Assistant interacting with it. I have been fighting with it for almost 6 months; I cannot keep a reliable connection. The Home Assistant community doesn't seem interested in helping solve the problem and I am becoming increasingly frustrated with the whole situation. I'm hoping maybe somebody here can help shed some new light on my issue and maybe lead me to a resolution.
Basically, randomly, the serial connection to the AD2Pi is just lost and never reconnected to, thus making the alarm status and controls unresponsive until I reboot Home Assistant. I'm not sure if it is a Home Assistant problem, a problem with the hardware, or a problem with the Alarm Decoder python dependency.

Any insights at all would be most helpful. Thank you!
