Is your feature request related to a problem? Please describe.

I name everything in my ha instance in a specific way to make my life easier when searching through entities. Currently the integration creates an binary_sensor entity without me being able to change the entity id or adding any prefix in the integration settings. Therefore I must go to the integrations page in settings and edit the entity ids there manually.

Describe the solution you'd like

As mentioned in the problem section it would be great to have the abilities to specify a prefix for every entity id as well as adding a option in the optional settings. It would enable a easy creation of tasks and also enable the user to shorten the entity id when necessary.

Describe alternatives you've considered

An alternative would be to edit every task after creation but this is tedious and not really scalable.

Additional context

Thanks for this otherwise awesome integration 👍
