Setup

• Install package requirements to your laptop

pip install -r requirements.txt

• Edit Configuration File "config.py"

ip_address = "192.168.5.5" # static ip address nodemcu esp

• Install hotspot software on your laptop, for example MyPublicWifi https://mypublicwifi.com/
• Open NodeMCU Code/ESP8266.ino using Arduino IDE
• Edit ESP Wifi Client Base on Hotspot Software "NodeMCU Code/ESP8266.ino"

#define STASSID "LEB-Monitoring"
#define STAPSK  "12345678"

• Edit ESP Static IP Base on Hotspot Software "NodeMCU Code/ESP8266.ino"

IPAddress ip(192,168,5,5);   
IPAddress gateway(192,168,5,1);   
IPAddress subnet(255,255,255,0);  

• You can adjust Static IP Address from hotspot software.
• Upload code to ESP using Arduino IDE.
• Set auto startup hotspot software using windows task scheduler for bypass ask administrator permission on boot.
• Set auto startup python to run start.py using shortcut like below:

/path/pythonw.exe start.py

Compatibility Operating System

• Windows 10
