Translation tables for dimmers?

Configuration
1

Has HA, yet, implemented translation tables for standardizing levels among dimmers?

It seems that many dimmers are designed with incandescent bulbs in mind, so LED bulbs end up being a lot brighter than incandescents would be. When I ask for anywhere between 15%-100% brightness, I pretty much get 100%. Setting the dimmer to, say 6% will actually give me about 30% brightness from my kitchen LEDs. And, of course, different brands of LED bulbs differ in their brightness.

Does HA have a way of assigning specific translations between what the user requests and what to actually send to the dimmer, on a per-dimmer basis? I’m thinking of something like:
when the user asks for (%), set the dimmer to (%)
10, 4
20, 6
40, 15
60, 25
90, 50
100,100
(So, if the user asked for 20% brightness, the dimmer would actually be set to 6%).

What you are asking for doesn’t currently exist.

If it were implemented, the conversion would have to be handled by each lighting integration (and the conversion would have to be bi-directional thereby making it slightly more complicated).

Which lighting integration(s) are you currently using?

Zigbee and Zwave.

Not sure why the integrations would need to be aware of it. HA gets a request from the user (via the UI or Alexa/Google/etc) of what percentage dimming they desire, so can’t HA just adjust that, on a per-device or per-entity basis, before handing the request to the integration for that device/entity?

They way home assistant is designed, each integration would need to add it to take advantage of it.

Typically what your asking for can be adjusted on your hardwares side.

For what you are proposing, each light entity needs its own cross-reference table, to convert the brightness level requested by the user to a different level transmitted to the physical light. It would also have to convert the brightness level received from the physical light to a different level for the light entity (that’s what I meant when I said it needs to be bi-directional).

Implementing this would require a significant architectural modification, specifically for how a lighting integration interacts with its light entities. You’d have to convince the development team of this proposal’s merits and then implement it if you have the requisite software development skills. If you don’t then you can compose a Feature Request and hope someone else will implement it.
