How configure a device (for example : set an switch backligth always off) automatically

I’m a beginner on HA and I have simple difficulty:
I want that the backlight of switches to be set to "off " regardless of a trigger. I know set it by an auxiliary entity or other automations types, but I want to set backlight off regardless of an action. The switch is always configured backlight “on” when energized (At Tuya integration there is a card “configuration” that ALWAYS sets this attibutes "on " after device power on) . I know that there is a way to create an automation that uses the HA initialization as a trigger but could happens that a device can be energized for any reason at any time and then this device assumes a default setup again. I´m using the backlight of a switch as an example but my doubt is valid for other devices too. NOTE: I don’t have yet good expertise to create templates or scripts, maybe they are the solution… I wil apreciate some examples.

When powering on the device, this entity attibutes always remains ON

`Entity attributes:

supported_color_modes: onoff
friendly_name: Zigbee Backlight 2 Keys
supported_features: 0
color_mode: null`


Update :
I obtained the result with an “obvious” automation which was the trigger: if the backlight stays “on”, then the action is to turn “off” the backlight.
This automation bypasses the default condition after any device power on.
But I’m still looking for a way to set an attribute as an initialization setup of a device (always keep an attribute in a given setup)

    entity_id: 0a0c36268133d829f9107489492f6df2
    domain: light
    mode: restart

Many thanks

If the device itself doesn’t allow you to configure this, an automation is likely the best workaround.

Hi Koying,

Thanks for your comments.

In fact the device has some attributes available to set but i can´t set up it using a direct routine without a trigger because is just a setup and not a cause - effect action .
But ok the way that I had managed works.
