Alarm device definition

---

It would be great to have a device definition for alarm devices like smokedetecors.
I developed thr protocol for FA20RF smokedetecors.

These send a message with their id as long as the alarm is turned on, so the device in pimatic shoud revert to state of after a configureable time.

The next thing is that we need a resend interval. You could use your smokedetecors as alarm for other things, like a window has been opened but you are not at home.
The smokedetector FA20RF turnes on for about 5 seconds when a signal was received once, so you have to resend the signal every 4-5 seconds. This interval should be configureable.

@Xento
you’re already succesful at this one on git pimatic/rfcontroljs#40 and pimatic/rfcontroljs#35
guess if @sweetpi has the time, he’ll merge it.
if you need any further help, i think @Icesory is your man

sound like “contact” in pimatic, triggered by an event “door was opened” and then reset to previous state after x seconds

I implemented the smokedetectors as switch.
But a real alarm device would be better.

Features that it should have:

1. optional reset of devicestate after x seconds
2. possibility to switch alarm on in gui and via rules
3. optional resend alarm every x seconds

@Xento Did you have a look at https://github.com/michbeck100/pimatic-alarm? Just add your feature requests as issues and i will see if i can implement them
