• Uses Real Time Clock Module (RTC) instead of internal NTP *But in the future new update, they can work together
  • The application doesn't broke if you don't have internet connection. Using just a internal NTP you need internet connection to init the application.
• Can schedule different days of the week and multiple times
• Can use a name for each schedule
• Friendly setup and web interface
• Doesn't need the wifi connection to work. *Is only needed to configure schedules

You'll need:

• ESP8266 Microcontroller
• Board driver CP210x (NodeMCU V2 and ESP32) or CH340G (NodeMCU V3)
• PlatformIO Core (Command line tool) or PlatformIO IDE for VSCode
  • Advanced usage - custom settings, uploading to SPIFFS, Over-the-Air (OTA), staging version

# Clone this repository
$ git clone https://github.com/rafaelbds04/esp-rtc-timer.git

# Go into the repository
$ cd esp-rtc-timer

• Change board PINS connections inside src/relay.h and src/rtc.h (if you need).
• Configure name and password of wifi setup access point inside src/wifi.h

# Build project
$ platformio run

# Upload Filesystem Image (/data folder)
$ platformio run --target uploadfs

# Upload firmware
$ platformio run --target upload

• Connect the ESP to your local network
  • Login into generated access point
  • Select your wifi SSID and type your SSID password
• Now you have the ESP connected to your network!
  • Get ESP ip address from serial port or your router
  • Open ESP ip address into your web-browser
• You already can control the schedules! 🎉
