Hi Prithul,
I have also gone down this path - albiet with WS2812 strip’s and poor grounding.
I came across this product in Core’s new product feed: Pololu Isolated Solid State Relay/Switch, SPST, 30V, 11A | Buy in Australia | POLOLU-5421 | Core Electronics
And have been meaning to deploy something similar to your project for ESP32’s, much like Core’s Nano power timer, but with a variable (controllable) sleep.
