How can the name of a Prisma device be changed?

If you have installed the Prisma devise in your network using either AirPlay or Google Home, you can make the name change in those applications. If you have not used either method, you will need to type the IP address found in the Settings menu under Information/System information in the Prisma application. Once you have entered the address and clicked return, a browser window will open up in which you can change the name of the device.

Newly added:
Device name can now be changed from Prisma app itself under the following SETTINGS:
Settings > Information > Rename device
