- The formatting of the code in the issue report makes it a little hard for me to read. However, it looks like you have moved the code that typically resides in the
loop
function up into thesetup
function, leaving theloop
function empty. Was this intentional? - Have you confirmed that your devices works fine with one of the example scripts (i.e. without the ESP deepSleep addition)?
- Does the problem only appear once you add the deepSleep line?

Hello. I'm pretty sure now that I have a hardware problem, your code is good.
If I connect the GY-30 sensor, ESP8266 doesn't even connect to WiFi even if I use external power for the sensor. If I attach the sensor (+3.3V line) after wifi is connected, it works fine... until reset/sleep. i2c bus is not stuck, so it must be something with the sensor.
Even your example code now works only if I connect power to the sensor after booting up, but it worked for the first time when I tried it.. :)

#include <BH1750.h>
#include <Wire.h>
BH1750 lightMeter;
void setup() {
Serial.begin(9600);
Wire.begin();
lightMeter.begin();
Serial.println(F("BH1750 Test begin"));
}
void loop() {
float lux = lightMeter.readLightLevel();
Serial.print("Light: ");
Serial.print(lux);
Serial.println(" lx");
delay(1000);
}
This is my code, I always get an error as "[BH1750] Device is not configured!
Light: -2.00 lx" , how can i fixed that error. I can't ger proper output.

If you’re using deepSleep, you should move all your code in setup block, not main loop.
