hello,
well i’ll have a issue…
i have a OLED display SSD1306 connected to my ESP32 to show Temp /humid from the bmp280.
have also a 4 x relay for light and a PWM channel for LED light dimming…
all works well and i’ll can display the states of the relay and all other info on my display…
the last info i’ll need is the PWM or lets say the light brightness value
i’ll have done some different constellations… but could not find any info on the web how to get that value on my oled…
here is my code:
- platform: homeassistant
id: grow1led_pwmx
entity_id: light.grow1_light
internal: true
- platform: template
name: "${device_name} brightness"
id: sensor_g_bright
internal: true
update_interval: 25ms
# Ensure on_value only triggered when brightness (0-255) changes
filters:
delta: 0.8
# Read brightness (0 - 1) from light , convert to (0-255) for MCU
lambda: |-
if (id(light_main).remote_values.is_on()) {
return (int(id(light_main).remote_values.get_brightness() * 255));
}
else {
return 0;
}
# On Change send to MCU via UART
on_value:
then:
- logger.log:
level: INFO
format: "Sensor Value Change sent to UART %3.1f"
args: ["id(sensor_g_bright).state"]
