"Burglary" notification - even with Security notifications turned off

Device: Vision 4-in-1 sensor

I’m using this sensor to trigger outside lights, and I’ve created a couple of scenes to arm and disarm it based on the light sensor, so it is only armed at night. This fits nicely with the UI as well - I can manually arm or disarm it with the built-in functionality, and it is visually indicated.

Trouble is, I get a notification when it detects motion if armed, even though I have notifications for “Security Alert” turned off.

Is this normal? I really would rather turn off all the default notifications and put in my own per device, but it doesn’t seem to work correctly.

I think I can answer my own question - it seems to come from the “Who should be notified ?” part of the Modes settings. Turning this off removes the notification, although it still appears as an alert in the UI.
