Sir, I studied your circuit (PDF document) and ... I'm at a loss. 1 - Connector P1. You called it a "battery", but judging by the presence of a C1 capacitor, this is an AC network. This is a valid solution, but. 2 - you send the VSEN signal directly to the input of the ESP32, without any filters and protections ... this is a very bad decision, sir. 3 - also a lot of questions with electric power 4 - you bypass the relay winding using a diode. This is a simple solution, but it is better to use a diode together with a zener diode. This will increase the reliability of the relay contacts. In general, I'm sorry, but your scheme is a little "raw" If you want, I can improve it, as well as fulfill your wishes.
