Input_datetime / set.datetime - Service not found Error

I started to receive this links of error trying to edit input_datetime entities.
In fact, the service doesn’t appear as a service available.
In states, the entities exist, but show as “Editable: false”, probably because of the absence of the service.
Anyone know what is going on?

No that just means you created it in yaml and can’t edit it through the UI.

OK, anyway, no input_datetime service is available:

I don’t know why it happened, but after some reboots the service is back… :upside_down_face:
