hello.
I need to turn on a switch if the brightness value of a light is =>1 and turn it off is <1. Is it possible from esphome, from the device’s yaml configuration file?
thank you.
If the brightness value is known to your esphome device, for sure.
What is the way to do it?
I create a template of a binary sensor that when the brightness attribute is greater than 1 it is in the on state and if not in off, and that this binary senser activates the switch
{% if state_attr('light.light_0', 'brightness') | int(0) > 1%}
A
{% else %}
B
{% endif %}
Am I well on my way?
Your code doesn’t look like esphome code.
Post a scheme of your circuit and your esphome yaml.
This is the current configuration of my device, now I want to put a contact online to the pwm regulator to deactivate it when the brightness is less than 1

Brightness is a value between 0 and 1, so it can’t be >1
For 1% it could be something like:
condition:
lambda: 'return id(light_0).current_values.get_brightness() > 0.01f;'
Hello.
I have finally found a more practical way to manage the switch than using the brightness attribute.
I have used the on_turn_on and on_turn_off functions, and my code looks like this:
- platform: monochromatic
name: "Luz dormitorio"
id: luz_dormitorio
output: luz_dormitorio_out
#gamma_correct: 0
default_transition_length: 10ms
on_turn_on:
then:
- switch.turn_on: luz_dormitorio_switch
on_turn_off:
then:
- switch.turn_off: luz_dormitorio_switch
Thank you so much.
