Interesting philosophies. I use a 10-channel fob with 4 buttons on it - you must use button combinations to acheive all 10 possible channels. It controls a 10-channel relay box I bought on line that I assembled myself - it's easy with the instructions. Anyway, the device is secured by the rolling code technology. I wired each relay NO contact to my PLC and programmed a particular sequence of inputs and timers that allow disarming the alarm.
This way if I lose my fob, who knows what the secret button combination is AND how do you know I don't have the PLC programmed to only respond to the proper sequence of commands???? and if you get the wrong sequence something might happen that you might not like too much..so watch out..I invite you to try it. hahah
Moreover, I use other inputs/combinations for other commands too. Since I don't use the typical HA controllers, I'm not sure how valuable this is and how complex the programming can be, but if you're interested I can show some pictures or put up a link to the relay box.
So, I arm my exterior garage door for maximum protection.
For status, I have an industrial stacklight in my garage that is visible from the car. The key fob's button press status is displayed on the stacklight so you have immediate feedback of successful button presses. In disarmed and armed states, the stacklight flashes ceratin sequences, all controlled by the PLC logic, indicating the state of the alarm.
And, rather arbitrarily I suppose, I disabled my garage door from being opend by the opener if the system is armed. This way the door will not repsond until the alarm is disarmed.
