Local helpers and scripts

[nedyarrd]

Describe your idea

Hello my idea is to create only localy visible helpers for devices. It might be very usable to have helper assigned to a device like additional sensor, accessible from automations. That local helpers can have repeatable names across whole HA instance, it should have unique names only in device space.

Why is this exciting?

It will clean mess with many helpers for devices which don't have ie power, energy sensors. It can implement power and energy sensors for devices, without creating additional scripts, using ie. mathematical filters, riemmans sum sensors to expand device.

Potential use cases

Can be helpful for managing energy devices, ie. lightbulbs, so we can create local helper assigned to that device, and use it to calculate power of that device dependent on device parameters such, power, colour, temperature.

Anything else?
