Hello, I am facing a strange behavior with my led installation. The issue occurs whenever I turn on the wall switch that is powering the led psu’s causing the leds to blink once or twice as red - and then moving on to the saved preset.
So for instance I set the preset 1 to All White, on turning on it starts of as white, around a second later flashes red, goes back to white and sometimes do it one more time. After that it remains white, ( think once it had an issues with full white brightness - doing the exact same thing but constantly each second or such turn on red ).
Sometimes turning on stuff in the household would cause also a one time red blink.
I am quite sure it has to do something with my transformers + esp setup because using the same wiring ( re-plugging it into an SP105E, doesn’t have any issues as above ) .

Brief explanation of the build.
The box is divided into 4 sections that control different rooms. Each of them has an individual dedicated power supply. Each of them is lit on by pressing a switch on the wall.
Now let me tell you about the things inside and its logic
- 24v->12v transformer - XL4015 step-down 5A 1.25V-36V DC-DC
- Relay - its a 2-channel power switching module, the purpose of that is to switch on the 12v fans on different conditions ( if psu1 is on and psu2 is off, if psu2 is on and psu 1 is off, if both are on ) - so it keeps the fans running depending on the wled setup running.
*PSU1&2 Step down transformers - LM2596S
*Wled1&2 - ESP32 ESP-WROOM-32U & Ext. ant Environment esp32 v3.3.6-16-gcc5440f6a2(0)
The transformers turn on when the switch is triggered, it steps down 24v to 5v to support the esp32, on the power line I added two capacitors (aluminum electrolytic + ceramic). The data is driven from GPIO 2 ( I02 ). Power got injected in 5V + GND.
Issues are with the PSU1+2 ( blue and green segment - excluding the relay ) - both behave the same way as presented on the video. All the PSU’s ( 1 and 2 ) are grounded - installation type is TN-C-S.
Feel free to ask me for more details and looking into for more tips, I rather don’t want to fallback for an SP105E cause lack of customization but will do if I can’t solve this. I did try v0.13.3 as well, same issue.
Sorry but I was unable to post more than one embedded image or more than 2 links.
Have a nice day, cheers.
