remotely via:
• smartphones
• tablets
• regular computers

Problems and Solutions
• Which problems had to be solved (and
how?) – and which remained unsolved
(and why)?
• How to display data server responses graphically
 Using AmCharts Graph library
• How to communicate with Data server
 by executing shell commands
• How to make service visible behind NAT and firewalls
 Auto SSH Reverse tunneling

Initially planned Achievements
Dashboard to display
sensor readings
„Historical View“ user can
select node, sensor.
Read measurements from
graph
Configuration module Already in framework.
modifications to be able to
use token as auth. SQL
Linux service control
module
Created init script to make
raspCTL run as daemon
Command API It is possible to Create /
Edit / Update / Delete
commands
Authentication module Admin user only

Conclusions & Outlook
• What would you make different, if you
started the project again?
 I would not use Python
 Not use Mercurial
 More collaboration with other teams
• Open points for future development
 Authenticate users using database
 Create actual commands for nodes
