Hello guys, I am building a iot project using 2 wemos boards where one acts as a counter which sends a high value when there's more than or equal to 1 person in the room. While the other acts as the relay system as well as window closing automation. I have an issue as when theres a person in the room i am unable to toggle the lights with my blynk app. but when the person exits i am abit to toggle. I have attached the counter as well as the relay code below. Thanks for the assistance guys:) [edited: i just added an image of how my circuit looks like below]
Relay code
