Feature Request: HealthCheck to report on offline 'critical' devices

it would be great if i could tell eero about 'critical' devices on my network (the eeros, sercurity devices, NAS/printers,  managed Dlink switches, electic vehicle charger, solar power inverter monitor, Rachio sprinkler system), garage door/gate gateway, Digital Logger web power switches and then have HealthCheck send me a text/email when it though one or more of those devices went offline for an extended period- maybe 30 minutes).   I have a few internet devices that attempt to do this now, but eero is in a place to do it in a consistent and predictable manner.
