CEC Commands For SparkBridge/+ Devices – VIDERI Support Portal

Staring in 2026, SparkBridge and SparkBridge+ models support HDMI Consumer Electronics Control (CEC) commands through the command-line interface (CLI). This article provides information about applicable CEC commands.

NOTE: Prior to using CEC commands, you must enable CEC functions on your externally connected display. See your manufacturer's guide for guidance.

NOTE: CEC behavior may vary depending on the display manufacturer, model year, and firmware version.

Launching The Command Terminal

CEC commands can be sent to SparkBridge/+ devices via the command terminal. To launch the command terminal:

Log in to Portal3.
Navigate to the Devices page.
Click the checkbox in the row for the target SparkBridge/+ device to select it.

NOTE: Commands can be sent in batch to multiple devices simultaneously. Select multiple devices during this step to send commands in batch.
Click the "Actions" button, located above the device list on the right side of the screen.
Click "Command terminal". Applicable commands are documented below.

The CEC Automation Setting

The global CEC automation setting automatically syncs supported CEC commands with the SparkBridge sleep, wake-up, brightness, and HDMI input behaviors. When enabled, the SparkBridge/+ automatically sends the following commands to the connected display:

Trigger	Display Behavior
Command: `sleep`	Turns display off.
Command: `wake_up`	Turns on the display. If the display was off, this command also sets the input to the SparkBridge/+.
Settings: brightness schedule	Turns the display on or off according to the configured brightness schedule.
Action: connect HDMI cable	Switches the display's input to the SparkBridge/+.

To enable CEC automation:

Open the command terminal as detailed above.
Type cec_hdmi_enable:=true.
Hit "Enter" (Windows) or "Return" (Mac) on your keyboard to send the command.

NOTE: To disable CEC automation, use cec_hdmi_enable:=false.

Additional CEC Commands

SparkBridge/+ models support additional CEC commands that can be deployed independently of the global CEC automation setting.

Command	Description
`cec_cmd:=power-on-function`	Turns on the display.
`cec_cmd:=power-off-function`	Turns off the display.
`cec_cmd:=input-select`	Changes the display input.
`cec_cmd:=otp`	Changes the display input to the SparkBridge/+ using One Touch Play.
`cec_cmd:=mute`	Mutes or unmutes the display.
`cec_cmd:=volume-up`	Increases display volume.
`cec_cmd:=volume-down`	Decreases display volume.
