@aaryansarat, your topic has been moved to a more suitable location on the forum.
Sounds like insufficient power.
Which relay / relay module are you using?
Can you please provide a schematic; reasonaby sized photo (approx 300 kB) of a hand-drawn one is fine; please pay specific attention to draw all power connections.
i am using 5v relay
The ESP can't provide much power. Where are your relay coils being powered from?
They are actually relay module I have connected 5v adapter 2amp to esp vin and gnd from that I took two wires and connected to three relays and three nano spray after that I will be powering 4 more relay modules
I think you had better give us the specifications (such as a Web link) to the relay modules you are using.
