What does "armed" mean in an item or thing?


I have some MySensors devices connected to OpenHAB via NRF24L01 trancievers. The MySensors binding offers me in PaperUI to configure an amed-item. Can I get notifications when an armed device has changed it state? How could I do it? Or for what else could I use it? This is my item config:

Switch buerofenster_armed “Armed” {channel=“mysensors:door:207a86b5:armed”}

My Platform information:

  • Hardware: RPI2
  • OS: Openhabian
  • openHAB version: 2.2.0
  • Issue of the topic: Don`t know what armed mean

Thanks for help…

Armed means it activated the secure mode, so once it is in armed state if you open the door it will trigger your alarm system.
