Switch in HA only stays on for 1 second - ESPHome + Sonoff

1

Hello everyone,

I am using a Sonoff SV to power a low power led. The problem is that when I turn on the switch in Home Assistant, it will be on for 1 second and turn off. The leds itself stay turned on, so only the Home Assistant interface behaves strange. Does anyone know what goes wrong? When I am quick enough to tap the switch again in HA before it turns off itself, the led will listen to that command and turn off. Here’s my ESPHome code. Thank you.
