Non-existent entity causes warning - once an hour

I have a strange entry filling my logs:

Logger: homeassistant.helpers.entity_component
Source: helpers/entity_component.py:55
First occurred: April 21, 2025 at 5:00:00 PM (21 occurrences)
Last logged: 1:00:00 PM

Forced update failed. Entity binary_sensor.updater not found.

Interestingly, I do NOT have a binary_sensor.updater sensor (Ok, that’s exactly it complains about). But I can’t figure out what is looking for it. I searched all my .yaml files and none of them contains the sting binary_sensor.updater.

Any idea where it may come from?

Cool, I’ve checked it out and it looks interesting. In the meantime I found the issue - I had an old references left over in one of my node-red flows.
