Good evening everyone , hope you’re having a pleasant day !
I have something that is a real head scratcher for me since i don’t consider my self as an electrical connoisseur or anything like that , i tried to follow some online schemas of basic RGB controller setups using Esphome and a node mcu ( tried both ESP32 and ESP8266 ) with home assistant , now when i put this setup into place , at first it works without problems but for some reason after a week of usage , my node mcu stops working ( i tried that with an ESP32 ( No more red light / or very dim red light ) and ESP8266 ( Constant blue light when it usually blinks once and works as intended ) ) , so i wanted to ask you guys if there is something that i’m doing terribly wrong that needs fixing in this setup , any help would be highly appriciated , thank you in advance.
Just a side Note :
The LC7805cv Voltage regulator gets extremely hot when the node mcu is not working, but when the node mcu works , it’s temperature is stable.
i tried replacing it , but i end up with the same result.
For the not-working ESP32 and the ESP8266 , when i plug them in with USB , they both become too hot to touch , but when i add a new ESP8266 that i bought , the temperature is fine.
I’m scared of being stuck in a loop of buying and replacing things because of my lack of knowledge.
any note would be really helpful 
It’s probably due to the power dissipated in the 5V regulator causing thermal shutdown. With a 12V power supply 58% of the power is wasted as heat in the regulator. You either need to add a heatsink to it or use a DC-DC buck converter (much more efficient).
Were you able to solve this issue? Would you please be so kind to share your esphome yaml code for the Esp32?
Thank you!
