Your Roku displays granular performance data like CPU temperature and voltage, memory usage, connected remotes and battery levels, and your SSID in the Platform menu. 

Even better, this screen is a hub for additional submenus: RF remote diagnostics, IPv6 settings, and a log of every remote button press since your last power cycle. Intense, right? To get to it, tap the Home button on your remote five times, then Fast Forward, Play/Pause, Rewind, Play/Pause, Fast Forward.
