Usage
-----

To use NEMS TV Dashboard, simply connect a computer (E.G., Raspberry Pi
Zero) to your TV display and open ``https://nems.local/tv`` in the
browser.

Fullscreen Mode
---------------

Ideally, make NEMS TV Dashboard fullscreen by pressing F11. Press it
again to restore the window.

Security
--------

For convenience and usability, NEMS TV Dashboard does not prompt for
your NEMS username and password by default. If you prefer to keep the
Dashboard private, please open `NEMS
SST <./nems-sst.html#tv-dashboard>`__ and turn off “Allow
TV Dashboard Without Password” - but make sure you have a keyboard
connected to the computer connected to your TV (or something like VNC
access) to login.

Under The Hood
--------------

NEMS TV Dashboard uses the Check_MK Livestatus socket in the back-end,
making it fast, efficient, and lightweight.

Requirements
------------

-  NEMS Linux 1.4.1+
-  A display of some sort, connected to a computer/SBC with Web Browser
   and network connection with access to NEMS server.
-  NEMS TV Dashboard requires a modern web browser to operate. If you
   experience issues, please test in a different browser.
-  NEMS Linux 1.6+ to include Internet speedtest at all times.
