In the article https://support.smartthings.com/hc/en-us/articles/209979766-Local-processing you can find the following statement:
If your devices and Automations meet all the above criteria, they will be able to run locally when an internet and/or power outage occurs.
** In the event of an internet and/or power outage, a SmartThings Home Monitor automation that tells your Aeon Labs Siren to sound when motion is detected by a Samsung SmartThings Motion Sensor will locally execute.*
This is exactly what I’m running: A SmartThings Motion Sensor and a Aeon Labs Siren (which both lists as local processing on the IDE page) and SHM alarm. Still, when I pull the plug to my router the alarm will not get triggered.
I am running the 2018 hub. On the IDE page -> Installed Smart Apps I can see the following:
Smart Home Monitor cloud.
Can I somehow change cloud to local or what am I missing here?
