Despite Notifications in Omada being checked for Event and Alert under Device Connected and Device Disconnected, Omada never shows any Disconnected status!  Only get CONNECTED status events.  Omada LOG does not show any Device Disconnected events or alerts.  

In the system, StarLink Internet, OC200, and Gateway ER7206 v1.0 as well as 3 AP's (EAP245, EAP225-Outdoor) are backed up by a 1 hour UPS.  Other AP's on the property are not.  For any extended power failure, the Omada GUI shows wired AP's disconnected, and mesh devices show heartbeat missing correctly.  However, the event LOG does not contain any hint of these devices missing, disconnected, or down.  

Without any UPS, the entire system is reported by Omada as OFFLINE.    I guess this is the common and clean way of handling it, and this works.    In a larger implementation, power outages can be more localized, or a UPS can keep some of it (including gateway and internet) up.  In this latter case, Omada node down notifications are missing or not working.
