ValueError: 'on_off_color' is not a valid Signal

[mjburton]

I've had an issue with HASS freezing up on a number of integrations for an hour at a time, three times a day at the same times each day. The only log entry between the times relates to the hue integration:

2023-05-16 06:31:09.235 ERROR (MainThread) [homeassistant] Error doing job: Task exception was never retrieved
ValueError: 'on_off_color' is not a valid Signal

During handling of the above exception, another exception occurred:
