/// LDR Config
#define LDR_RESISTOR 1000 //ohms
#define LDR_PIN A0
#define LDR_PHOTOCELL LightDependentResistor::GL5516

I don‘t really know where the Problem is.
Maybe you try it with wifi First.

Do you Connect the Controller via USB cable or direct with Rx Tx and GND?

I connect the controller via USB cable; Can I use Serial to connect the ESP8266 and my raspberry pi?

[Mazze2000]

Yes you can use one of it.
Do you try the connectrion via wifi?
Please note: If you change the connection in the server, you have to restart the server.

Yes, It works when I use WIFI, but USB didn't, Thanks so much!
