Ghost entity

Hello friends,
I have an error that haunts me:

2020-04-16 19:06:03 WARNING (MainThread) [homeassistant.helpers.service] Unable to find referenced entities media_player.home
2020-04-16 20:06:15 WARNING (MainThread) [homeassistant.helpers.service] Unable to find referenced entities media_player.home
2020-04-16 20:06:16 WARNING (MainThread) [homeassistant.helpers.service] Unable to find referenced entities media_player.home

but I don’t have this entity!
I can’t find it in any configuration file.
Give me an idea, thanks.

Do you use packages?

no, i don’t use them and for media players (google) and tv i use integrations

I’m banging my head, can no one help me?

I am having this same issue. They are entities left over after trying to reconfigure MQTT. How do I remove them?

I had something similar.
Only in my case it referred to an identifier.

Unable to find referenced entities switch.0x086bd7fffe03e063_switch

I found that one of my automation rules was calling this entity, but it was a nonexistent device.
I probably deleted it and forgot to edit the automation rule
