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

Results

• Features and Tasks

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
