### Firmware install

Please install first [PlatformIO](http://platformio.org/) open source ecosystem for IoT development compatible with **Arduino** IDE and its command line tools (Windows, MacOs and Linux). Also, you may need to install [git](http://git-scm.com/) in your system. 

Before the first run, load the icons and assets with:

```bash

pio run --target uploadfs

```
