Hello,
I am using an LCD display with an I2C converter together with ESP Easy. Everything is working fine.
But now I want to ad a proximity sensor which turns on the display when somebody is in front of the display.
Is it possible to switch of the backlight of the display?

Can I control the backlight of an I2C LCD display?

Backlight can be switched off by your controller using the following http: command:
