ChromeOS is a platform by Google that is a simplified operating system based on Linux that runs web applications. Google has invested in supporting the digital signage ecosystem with their operating system and there's a number of good options in order to deploy on this platform.
Advantages and Limitations
ChromeOS has a number of advantages. Chiefly these devices are the most inexpensive option you have to deploy at scale. While there's a significant investment of time and technical expertise to understand Google's device management system the devices themselves can be very inexpensive. However, there is generally poor support for ChromeOS devices outside of the United States, so you may need to check on device availability if you're outside the USA.
A significant limitation is that ChromeOS devices can not be configured to boot directly in to the TelemertyTV media player unless you've purchases and configured the appropriate licenses from Google and the device is setup to be provisioned by TelemetryTV. Simply pairing the TelemetryTV app will not provide a seamless experience.
Selecting and Purchasing a Hardware Device
We recommend the CTL Chromebox 1. You can purchase this device direct from CTL. It's inexpensive, well supported and supports 4k. TelemetryTV has made a relationship with CTL for a Chromebox that may be purchased pre-provisioned to your Chrome system:
If the CTL box is unavailable to you or you are looking for something slightly different a good alternative to the CTL Chromebox is the ASUS Chromebox 3.
Important: We do not support using the Chromebit as it's too underpowered for most TelemetryTV applications and will suffer from thermal throttling. Additionally Chromebits have known issues where they seem to be unstable with retaining their application cache and could go offline and not recover correctly.
For touch screen applications you can also deploy touch screen Chromebases.
Pairing vs Provisioning Devices
For testing and very simple use cases you can deploy TelemetryTV on a ChromeOS device as you would on Windows. Search the Chrome store for TelemetryTV and install the media player then run it. Once it's running enter the displayed pairing code in TelemetryTV and you'll be paired with the device. Please note that a paired ChromeOS device will not boot in to the TelemetryTV app, thus this isn't suitable for deployment in most situations. We suggest using Chrome Enterprise and Single App Kiosk Mode to allow the device to boot in to the TelemetryTV app.
For digital signage applications the desirable feature of ChromeOS is called Single App Kiosk Mode. This allows a managed Chrome device to boot directly in to the TelemetryTV application without user intervention. You can therefore use this to deploy Telemetry to many devices without needing to interact with each device any time there's a power failure or device software update.
Single app Kiosk Mode requires a Chrome Enterprise license for the device.
Chrome Enterprise is Google's management system that lets you manage multiple Chrome devices through a single interface. It provides policies that allow IT departments to deploy and manage at scale. For more information, including how to purchase licenses please see the Chrome Enterprise website.
Purchasing Single App Kiosk Licensese
There is a special license designed for digital signage that is less expensive ($24 USD per year) than the general license called Single App Kiosk. Talk to your Chrome reseller for more details.
You must purchase an annual Chrome Enterprise license from a Google reseller for each of your ChromeOS devices you want to use with TelemetryTV and automatic device provisioning.
Ensure The Latest ChromeOS Version
Make sure that you're using the most up to date version of ChromeOS on the device. When purchased some devices can have older versions of ChromeOS which will be unpredictable with TelemetryTV. ChromeOS will automatically update itself once it has been connected to the Internet for a while.
Using Google Admin
The use of Google Admin to provision and manage devices is a complex subject. As such please see our article on using Google Admin.
