On this blog we'll share with you the eHomeAutomation apps works also with NodeMCU ESP8266 module and giving the updates on the display status of temperature and devices.Material used
1 x NodeMCU ESP8266 with CH3401 x NodeMCU Backplane
1 x 4-Channel Automotive 12V Relay
1 x DHT11 Breakoutboard
1 x SSD1306 OLED Module(*one color)
1 x 12V Adaptor 2.67A (PB-1320-01C)
2 x 1pin jumper wire M-F 40cm
7 x 1pin jumper wire F-F 20cm
6 x 1pin jumper wire F-F 40cm
Its only P 1,156.25 (of all the items above)
Provide other materials such as

Instructions
Router- Set your router gateway to 192.168.0.1 port 80 and subnet 255.255.255.0.
Wiring Diagram
4-channel Relay 12V to NodeMCU ESP8266
See the Wirig DiagramNote: NodeMCU GPIOs output voltage is 3.3V so we need only use +3.3V for the power supply for SSD1306, DHT11, and on the VCC of the Relay.
For Power Supply:
12V Adaptor (PB-1320-01C)
CAUTION: HIGH VOLTAGE! DO THIS AT YOU OWN RISK. (Make Sure you follows the safety precaution - relay contacts has pins at the bottom, use anti-static mat or place it on a non-conductive surface)
Uploading the Arduino Sketch
1. Open Arduino IDE 1.8.13 or latest version.
2. Open the DeviceControl.ino from the HomeAutomation Library then modify some line of codes in SSID, PASSWORD sections
Visit the eGizmo github for HomeAutomation library, DHT and Adafruit_SSD1306 library. Click here
Note: Do not change the default IP address 192.168.0.200 because this will be the ip communication for home automation app on your mobile phone.
The code
About the app
Install the ehomeautomation app (apk download here)
From your phone go to your Settings> Wifi settings> connect to your ssid and password.
Now OPEN the apps (Actually you do not need to type or anything the ip address, it just automatically connected)
Enjoy!
