Hi! Thanks for the praise!We're not very familiar with Web GUI but you can definitely control your Volumio app via your web browser by simply opening your Prota access link on it. It's unfortunately not possible to synch your phone with volumio but you can write up an automation workflow using Stories and IFTTT that starts music when your smartphone enters your home area and stop music when it leaves it. That way the music will automatically turn on when you reach home.
