How to delete notifications?

Configuration
1

I did incorrect automation, as a result I have more than 6000 notifications.
How to delete notifications programmatically?

2

I find they disappear if I restart Home Assistant…

You’re right. But there were entries in logbook. Can I delete them?

4

You can’t… they will drop off depending on your recorder/logger settings though… Or if you really have to you could stop HA and then delete the database but then you lose everything…

Ouch.

Could be worse. I once sent 10,000 SMS messages over a weekend while developing a product for Telstra. All I got as recompense was a free lunch.

Thanks, I do not want to delete the database. How long does a logbook keep records?

7

Unless you have set this differently the default is 10 days: https://www.home-assistant.io/integrations/recorder/#purge_keep_days

can i change the storage time in the logbook? This interests me because I would like to keep records, such as temperatures for a longer time

The logbook only presents data from the recorder. So it depends on that same purge setting.

It is a global setting. You can’t store different sensors for different numbers of days.
