Hi all,
I have recently got a Shelly RGBW2 to control my fish tank’s RGBW led strip.
I want it to ramp up the brightness and dim during the course of the day - I’ve done something like that in arduino ages ago, however ESPHome/yaml is new to me.
Not sure how reliable it is, but I got the scheduling bit of code from ChatGPT and it seems to make sense. What i’m struggling now is integrating my current code with the scheduling code. Any chance someone could give me some pointers ?

ChatGPT’s suggested implementation to control some lights ramping up/down brightness between 3 intervals:
esphome:
name: my_lights
platform: ESP8266
board: nodemcu
logger:
level: DEBUG
wifi:
ssid: "your_wifi_ssid"
password: "your_wifi_password"
api:
web_server:
light:
- platform: template
name: "Light A"
id: light_a
lambda: |-
auto now = time(nullptr);
int total_minutes = now.tm_hour * 60 + now.tm_min;
float brightness = 0;
int start_minutes_1 = 10 * 60;
int end_minutes_1 = 15 * 60;
int start_minutes_2 = 15 * 60;
int end_minutes_2 = 19 * 60;
int start_minutes_3 = 19 * 60;
int end_minutes_3 = 22 * 60;
int duration_1 = end_minutes_1 - start_minutes_1;
int duration_2 = end_minutes_2 - start_minutes_2;
int duration_3 = end_minutes_3 - start_minutes_3;
float max_brightness_1 = 50.0;
float max_brightness_2 = 80.0;
if (total_minutes >= start_minutes_1 && total_minutes < end_minutes_1) {
brightness = total_minutes - start_minutes_1;
brightness = brightness / duration_1 * max_brightness_1;
} else if (total_minutes >= start_minutes_2 && total_minutes < end_minutes_2) {
brightness = total_minutes - start_minutes_2 + duration_1;
brightness = (brightness / duration_2) * (max_brightness_2 - max_brightness_1) + max_brightness_1;
} else if (total_minutes >= start_minutes_3 && total_minutes < end_minutes_3) {
brightness = total_minutes - start_minutes_3 + duration_1 + duration_2;
brightness = (duration_1 + duration_2 + duration_3 - brightness) / duration_3 * max_brightness_2;
}
return brightness;
I tried putting the lambda in so many places, but keep getting yaml indentation errors.
Would really appreciate some help.
Thanks!
