I created a sensor template to test something in the configuration.yaml.
Later I deleted that code from the config after testing as it was no longer needed.
However even after reboot that entity is still there and no longer updating since it is actually deleted. When I click the settings icon of the entity it says
Blockquote
This entity (‘sensor.abc’) does not have a unique ID, therefore its settings cannot be managed from the UI. See the documentation for more detail.
I am not sure what I can do to get rid of it as I cannot even set it to inactive. I don’t want my setup being cluttered with zombie entities.
