Apologies for asking for help on a common topic, but this aspect is so hard for me to wrap my brain around for some reason.
Since SimpliSafe won't allow integration other than arming via Alexa, etc. I have setup a virtual lock (SimpliSafe Alarm) in hubitat and then use a tablet, pushover, and Tasker to synchronize and leverage Autoinput on the tasker/tablet to 'push' the alarm mode or disarm.
My cancelling action I'm trying to figure out, is that if the actions fail, I want to get a pushover notification to my wife and I's mobile that the alarm either did NOT arm/disarm as desired so that we know to manually do so.
