Some commands are postfixed with ``cmd``, indicating device specific commands. Not device-specific commands are genericly applicable to all *Adafruit Graphics* enabled devices, using the ESPEasy ``AdafruitGFX_helper`` module.
|
|
|
|
Commands can be sent from several sources, from the Tools page using the Submit button, from Rules, and via the webbrowser address bar or other applications that can open an url.
|
|
|
|
When using the Tools or Rules route, the commands shown here can be used as displayed, when using an url, a command should be prefixed with: ``http://<esp-ip-address>/control?cmd=``
