CUE 1™ is a simple app that allows users the ability to control the ETC Eos®/ Ion® family lighting software via their smartphone or tablet.

Here are just a few of the commands that have been integrated into CUE 1.
-- Channel
-- Address
-- Go To Cue
-- Group
-- Park
-- Rem Dim
-- Next/ Last
-- Macro
-- and more...

CUE 1 utilizes the UDP string interface option that was added to version 1.9.5 of the Eos®/ Ion® family software.(You must be running version 1.9.5 or later for CUE 1 to work).

IMPORTANT: The device running the CUE 1 app must be connected to the same wireless network as the Eos®/ Ion® console. (This means that you must have a wireless access point within your lighting system in order for CUE 1 to work).

Currently CUE 1 is a one-way communication application. CUE 1 only has the ability to send information. It does not receive information from your lighting software.

Basic and gets the job done

Good app for ease of bringing up channels group or cues. Don’t expect it to the iRFR app and you won’t be disappointed. Basic cheap and saves you 800 walks to the console. Easy to set up too.
Highly recommended for students who are learning about the eos software as well, baby steps.
