Now it’s time to view the application in your browser to check whether the GUI works as well. Just enter the ip address or hostname of your RaspberryPi in your browser.
Did you install using a monitor attached to the RaspberryPi and you don’t know what address your device has? Just type
ifconfig | grep addr and it should display an ip address, for example:
eth0 Link encap:Ethernet HWaddr b8:27:eb:f4:24:de inet addr:192.168.178.150 Bcast:192.168.178.255 Mask:255.255.255.0 inet addr:127.0.0.1 Mask:255.0.0.0
In this example the ip address is
192.168.178.150. If possible, you should assign a static ip address to your device in your router. This will make sure you will always be able to find the application at the same location.
You surely want to
reboot your device and check whether everything comes up automatically again with
sudo supervisorctl status. This will make sure your data logger ‘survives’ any power surges.

If you expose your application to the outside world or a public network, you might want to take additional steps:
