@oscopeaaron The notifications feature only supports one at a time. We wanted to have the feature be useful, but also simple. Having said that, you can automate them any way you like. So you could have an automation that checks something every few minutes and then enables the notification. For example, check to see if the garage door is open and hub safety monitor is in an armed state. If they are true then flash the LED blue for 10 seconds (for the garage) and then have the LED turn red indefinitely (for the armed state). This could repeat every x minutes.
With the flexibility of Hubitat, there is a lot you can do.
