I have been busy getting my alarm system setup and so far pretty happy with it, going to mount a tablet at the front door as soon as the wall mount is delivered. I am using the MQTT Alarm App for that. As I put this together I realized there is no good way to know other than to check Home Assistant if the Alarm is set which results with the alarm going off when letting out the dog. Since the front door is pretty visible from most areas of the first floor I thought of mounting an addressable LED strip in the top moulding. The idea then would be to turn one LED on as Red when the alarm is set. I could also do a visual countdown over 30 seconds for the exit delay (all on to off). When the alarm goes off I could flash the LEDS Red and Blue. Other ideas include turning one led on (Blue) if mail was delivered, another could be to turn on less if motion was detected on one of the security cameras (turn on several but slowly turn them off as time passes).
So I have been searching the internet for ideas or example on how to put this together. I would prefer to use ESPHOME as I am getting comfortable with it. So could use the FASTLED platform. One of the key considerations is to control the light from Home Assistant. Wondering what the best way to accomplish this. I had considering creating effects but not sure that would work for situations where I would want to show multiple notifications (alarm on and motion detected).
Examples are always welcome if someone can point me in the right direction.

FASTLED
did you found a solution?
I never got a response on this thread but did put something together which I included here. Some of my ideas didn’t make it (like the visual countdown) But most of the others did. This configuration is far from perfect but it works.
