This program allows you to remotely control a device hooked up to one of the GPIO pins on an ESP board as well as scheduling its work. Everything is controlled through a web interface which allows to switch between different working modes (manual or automatic), managing the pin state when in manual, scheduling automatic on and off turns and setting WiFi credentials.
- Easy-to-use web panel
- Manual and automatic GPIO control
- Schedule-based automation
- WiFi and clock fallbacks
- NTP time synchronization with manual time fallback
- Configuration files in persistent storage (LittleFS)
- Clone repository
git clone https://github.com/unknow1192/RemotePinControl- Open folder in Visual Studio Code, make sure that Platform IO extension is installed
- You can adjust few things in source code
- Pin that you want to control, form
src/pin_controller.cpp
#define CONTROL_PIN D10 // Choose which GPIO pin to control
- Timezone in
src/time_manager.cpp
setenv("TZ", "CET-1CEST,M3.5.0/2,M10.5.0/3", 1); // Default timezone is GMT+2 (Poland)
- ESP board model in
platformio.ini(default one is Xiao ESP32C3) - WiFi credentials in
/data/settings.json. These can be changed later from Web UI. When unable to connect to an existing WiFi board will start its own wireless network:
Then after logging into that network and going toSSID: ESP32-PinControl Password: 12345678192.168.0.1address you can put or change your WiFi credentials as well as boards own credentials when in access point mode. - Pin that you want to control, form
- Connect your ESP to your computer, click on Platform IO tab -> Build Filesystem Image -> Upload Filesystem Image -> Build -> Upload
- Open the board's IP address in your web browser, then configure schedules or control the GPIO manually.
After starting program automatically tries to connect to WiFi and get time data from NTP server. If unable to connect to WiFi as client after 10 seconds it enters access point mode. After that it is usually unable to get time info so it automatically locks scheduled actions, only operates in manual mode. Same thing happens when able to connect to WiFi but unable to get time info. To allow to do scheduled tasks you need to enter time data manually. It can be done in Settings section. After saving new WiFi credentials board will reboot itself and try to connect to new network on boot.
To minimize the number of operations on ESP some of the validation happens in JavaScript on client-side. It is advised not to use this app in open networks, "in production" or anywhere else, where third parties have access to the control panel. Some testing was done on a Xiao ESP32C3, but not every case has been tested, and only on that one board. Author does not take any responsibility of potential damage caused.
