Hi cweemin, thank you for your example and confirming it is possible.
I went over my commented out previous attempts and I see where I went wrong, the values and most importantly because I let Openhab detected my stuff in PaperUI so I didn’t need to touch the items file manually, just needed to enable ArmMode item in PaperUI and used your mappings in sitemap.
Thank you for the great plugin and help setting it up. Now I got Alexa to announce the messages and arm system, but not disarm(safer).
