active-low, ie they are triggered with a negative pulse, in which case you can configure it like this: ODev.addDevice("light", 9, Device::DIGITAL)->invertedState(); |

In this example we created our own application to connect and manipulate devices directly, this model is very similar to Android development. The OpenDevice project provides a standard server (opendevice-middleware) that contains a dashboard for management, visualization, and storage that you can use and customize to create your project.
