In that case devices should be known and should not trigger additional notifications.
Is it just printer or any other devices?
However there are few possible causes, why devices might be forgotten.
- Did any unexpected reboots (power outage, force reboot, etc) happened?
pakon-dev-detect depends on data that are partially stored in RAM and then saved to persistent storage once per day. If your router was hard rebooted before that, data and new-known devices from that period are lost.
On the other hand data should be saved during regular reboot or system service restart, so that shouldn’t be a problem.
- Perhaps there is a bug and data aren’t stored properly.
We are currently investigating that and you can track progress here
Unfortunately, it is not possible right now.
