4.2 Power Saving & Management

CollabOS Power Management helps you deploy your video conferencing rooms in an energy-efficient manner. Take control of your device's energy consumption with features like power savings mode, HDMI CEC support, and auto wake-up.

Logitech CollabOS devices including Rally Bar, Rally Bar Mini, Rally Bar Huddle, RoomMate, Tap IP, and Tap Scheduler support Microsoft Teams Rooms Office Hours and Zoom Rooms Device Operation Time and Idle Time-Out.

1After 10 minutes of inactivity in the room, the power saving mode will start. Supported TVs will be turned off if they are inactive.

2Requires a Tap or Tap IP or a Touch Display to be connected to the room system.

Note: 

CollabOS devices use CEC to turn displays on and off, we recommend testing your display's CEC support for ensuring compatibility.

Service Provider Settings

CollabOS power management configurations are specific to service provider settings. For Microsoft Teams Rooms and Zoom Rooms please follow the instructions from the service provider.

Microsoft Teams Rooms on Android

When using Teams, the CollabOS power-saving setting is disabled since this setting is managed by the Teams Admin Center. 

1By default, office hours schedule 8 am - 5 pm is applied

2Power saving settings in Teams Admin Center must be disabled for Office hours to apply

Office Hours

CollabOS devices will have office hours enabled by default from  8 am to 5 pm, even if a configuration profile is not pushed. To configure a different office hours setting, create a Teams configuration profile in Teams Admin Center and push it to the device. Here are different scenarios and their corresponding results. 

Idle Mode

Idle mode means that the device wakes up only when it is being used or when motion of people are detected in the room. When there is no activity, motion, or people detected, the device will go to sleep. To enable "Idle Mode" with Teams, you can set a short office hours time span, for example, 07:00 am - 08:00 am. This ensures that the displays are on for only 60 minutes. After that, the device will remain in power saving mode until a meeting is started or motion or people are detected. 

Auto wake up displays when people or motion is detected

If you want the display to turn on automatically when a person or motion is detected, you need to enable CollabOS setting "Auto wake up using AI viewfinder" for people detection and "Auto wake up using Tap sensor" for motion detection. This feature only applies outside scheduled office hours. 

Zoom Rooms

The CollabOS power saving setting is disabled when using Zoom Rooms since the setting is managed by the Zoom device management portal. It is recommended that you turn off the Tap sensor option in CollabOS when using Zoom Rooms.

1Requires Zoom device management settings "Count the number of people in the room" and "Use supported hardware for real-time people count" to be on. 

Control with Schedule

Control with Schedule is a power-saving mode that is managed via the Device Operation Time feature in the Zoom device management portal. It allows you to schedule when the display should turn on and off. You can learn more about how to enable Control with Schedule by following here.
