Step adjust brightness

Configuration
1

Hi all! I’m trying to create a script that adjusts brightness up or down. This will be addressed from a Loxone Miniserver to turn brightness up or down from a switch.

I created this script similar to another one related to volume (Sending Jinja2 templates in an HTTP Request? - #8 by petro), but didn’t work. Probably because there is no “state_attr” called “brightness” for “light”. Anyone know what the “state_attr” would be to detect the brightness of a light bulb?

Thanks.

I don’t know exactly what’s the problem in your code, but are you aware the light actions support changing brightness by step by default? With brightness_step. You should be able to use that to simply adjust the brightness by a specific step.

Also brightness value goes from 0 to 255 and is an integer. Try adjusting it by an integer, not a value below 1.

You can find this and more info about the light actions in the documentation here:

Thank you! I was not aware of that… I assumed it was not possible given that it wasn’t for media_player…sorry I’m still a newbie! I’ll post my updated code when I have a working solution for future reference
