Remove auto-discovered Google Cast

Configuration
1

Hi,

home assistant auto-discovered a Google Cast device. Since I’m not using it and I’m trying to get the system back to a minimal state (I’m getting timer reset warnings), I want to remove it from the HA system.

I found several discussions on hiding it. But since this information must be stored somewhere, I want to check the list of auto-discovered devices and remove unnecessary entries. How can I do that?

This post is old but it’s the first that showed up in Google when I had this same question. What worked for me was deleting the Google Cast device entries from /config/.storage/core.device_registry, /config/.storage/core.entity_registry, and /config/.storage/core.config_entries.

I removed them, ensured google_cast devices were set to ignore in the discovery component, then restarted the server. This succeeded in getting rid of the discovered Google Cast devices.
