LTR390 different gain and resolution for ALS and UV

[tgrosz]

Describe the problem you have/What new integration you would like

The LTR390 uses one gain and resolution setting for both ALS and UV measurements. Outdoors it's not the best solution.

Please describe your use case for this integration and alternatives you've tried:

I'd like to use smaller gain and resolution for ALS measurement outdoors, so that both ALS and UV measurements would be usable

Additional context

In arduino lib example code, they are used with different values https://registry.platformio.org/libraries/levkovigor/LTR390/examples/ltr390/ltr390.ino

[latonita]

@tgrosz ltr390 doesnt support different gains for als/uv. That library is just switching gain and mode and then read data. I think I can update the component to do similar approach.

[latonita]

@tgrosz try it.

Gain can be set as usual - same value for ALS and UV (

    gain: X18

or granular

    gain:
      ambient_light: X9
      uv: X3

external_components:
 - source: github://pr#7026
   components: [ltr390]

sensor:
  - platform: ltr390
    uv_index:
      name: "UV Index"
    uv:
      name: "UV Sensor Counts"
    light:
      name: "Light"
    ambient_light:
      name: "Light Sensor Counts"
    gain:
      ambient_light: X9
      uv: X3

[tgrosz]

Hi @latonita , thanks - as I see it's working OK. My idea was the same - to set the gain before reading the value

[latonita]

@tgrosz please test separate resolution. similarly:

resolution:
  ambient_light: 20
  uv: 13

[tgrosz]

@latonita I get error message Unknown value '{'ambient_light': 18, 'uv': 20}', valid options are '20', '19', '18', '17', '16', '13'. resolution: ambient_light: 18 uv: 20 I cleared build files, what else should I do?

[latonita]

Share your config please. Ltr390 part

I have an idea - check if you have white spaces like this 'resolution: ', remove if they exist. I will check this also

Tried deleting indentation and adding spaces manually, did not help

This is strange. Please send full yaml

Strange, now it compiles without any change. Maybe some cache issue. So, it works, Thanks
