ESP8622 Timer w/ NTP Sync and Remote Control

The idea is to have a device that turns on and off one of it's outputs at a certain time of the day, and also having the possibility to override the timer and toggle the output remotely

To keep the clock synchronized the device uses the Network Time Protocol (NTP)

Timer Defined State and User Override State

Base Timer Function

If the timer is set (timer_enabled == 1) then after a defined amount of time, the current time gets compared with the timer-set values, if the current time fits inside the interval defined by the timer then the output pin (MAIN_OUTPUT_PIN) gets pulled up and keeps in that state until the current time no longer belongs to the interval or if the user manually changes the output state, in which case the timer deactivates

User Override

If the user overrides the state of the output then the timer is deactivated (timer_enabled is set to 0)

Dependencies

The project is developed using PlatformIO Core which does the compiling, uploading to the board and dependency management, but the same code can compiled (with some light changes) using the Arduino IDE.

Building and Uploading to the Board

Clone the repository and navigate to the folder

$ git clone https://github.com/mjkloeckner/esp8266-timer.git

Then install the required libraries for the project

$ pio pkg install

Compile the code

$ pio run

Or even better, if you have the board connected, compile and upload at the same time

$ pio run -t upload

Finally upload the files to the filesystem of the board

$ pio run -t uploadfs
