How to simplify creation of template sensors for each area

Hi,

Apologies if this has been asked before.

With the excellent capability to use macros in templates, I’m refactoring my template sensors to simplify maintenance.

Most of my sensors are for each area, and so there is still a lot of repetition that I have to write and maintain them.

Does anyone have any tricks or ideas of how we can simplify creation of a standard set of sensors for every area?

thanks.
