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. |
