In the Scheduler custom component, when a name is entered or edited in “Options → Name”, the Scheduler card displays “Could not connect with the scheduler component. It needs to be installed as integration before this card can be used” and the Scheduler card disappears
In Settings → Devices & Services → Integrations → Scheduler → Entities, the entry that was modified is marked “This entity is disabled.” Enabling the entity generates a message that the entity will be enabled in thirty seconds. After thirty seconds, if the Scheduler card is refreshed in the browser, the schedule card is again visible.
The installation is as “Home Assistant Operating System” on a small form factor x86 Byte3.
Any ideas? This is very inconvenient…
