Hi all,
I applied the latest ESPHome update (2023.12.1) to HA tonight and then updated all my online devices (17) and all but one went fine and that gives a validation error as per the title?
I’m no coder so don’t know what would have changed before and after the update that would bring this error as an issue?

When I validate it says:

Pin 4 is used in multiple places.
I understand what ‘Pin 4 is used in multiple places’ appears to suggest, just that if it was an actual issue, how could it have been working all this time and what to do about it now please?.
