Further, the system has the RealVNC host screen sharing software already
installed and configured to allow you to connect to the device using any VNC
client equipped laptop to view and control the device remotely. With proper
IP routing, you could conceivably access this system from anywhere.
In its first iteration, the EVTV Battery Display uses User Datagram Protocol
(UDP) packets to communicate with the ESP32 Battery Module Controller
using the broadcast IP address. And so if they are both connected to the
same TCP/IP Access Point (your home wireless router) the EVTV Battery
Display will present data from you Battery Module Controller.
In this way, you can put the display anywhere in your home to monitor your
solar energy storage system with no wired connection at all.
Additionally, the device has the ability to pass data using Amazon’s AWS Iot
Core cloud service to echo data to a second display located anywhere
worldwide.
And finally the display itself can act as a web server to display historical
data held in an internal MySQL database.
