[Feature] Ability to ignore errors in notifications

[phyber]

Is your feature request related to a problem? Please describe.

In my Zigbee network, it is normal for some devices to sometimes be turned off at the power (eg. overhead lights). This results in the Z2M frontend complaining loudly via notifications when it can't ping, or get some data from a devices that is powered off.

Describe the solution you'd like

I'd like to be able to prevent errors from showing up in the notifications, possibly on a per-device basis. If this isn't possible, it would be preferable to simply disable the notifications in the frontend entirely.

Describe alternatives you've considered

The only alternative would be for the devices to be powered on all of the time, but that's not possible.

Additional context

This would be great, I have the exact same situation and often the notifications can't be dismissed quick enough to access the page.

Please give us control over what notifications are displayed over the frontend.

The messages to affect user experience in portal plus, those are from devices I expect to be offline.

Update: I was able to workaround the problem by disabling availability on each device I expect to be offline. Details here: https://www.zigbee2mqtt.io/guide/configuration/device-availability.html
