The React Native app switches command components on a connected objet; like a Raspberry Pi or a microcontroller. The commands go through a MQTT server. The target RPi or MCU sends back the change of state through the same MQTT server. The app shows the state of each component on the RPi or the MCU. The outcoming and incoming activities are saved to an online database, FingoBox, and display the history within the app.
