Schedule TV Power On/Off, Volume, Brightness, Mute through HDMI-CEC with OptiSigns

HDMI-CEC is a popular feature available on most of the consumer TV right now. It allows the connected devices to communicate to the TV and also send control signals. With HDMI-CEC, you can send control signals to power on/off the TV, as well as adjust brightness, volume. 

If you are on the Pro+ plan and using the OptiSigns Preconfigure Android Player, you will have the capability now to set up schedule to power on/off your TV, and also adjust brightness and volume of the TV based on a set schedule, if your TV supports HDMI-CEC. For example, you can setup a schedule to power off yout TV at night and power it on only during business hours, this will help save power and extend the life of your TV.

Currently, with the advanced scheduling feature for HDMI-CEC, you can set up schedule for:

  • Power On/Off TV
  • Adjust the brightness
  • Adjust the volume
  • Mute the TV

To set up the schedule to Power on/off the TV

Go the screens you want to setup the schedule and click Edit.


Expand advanced in the Edit Screen popup.



Go to the bottom of the Edit Screen popup, under the section "Schedule Power,Volume,Brightness,Mute", you can create a new Schedule.


Then you can create a schedule to manage the TV power on/off and other tasks like mute. The use of the scheduling is the same as the content scheduling. If you have questions on how to use it, you can refer to this article.


When you create schedule event, select a type that meet your requirement. In this case, it is Power Off TV. What it does is to power off the TV at the beginning of the time window, then power it back on at the end of the time window. Then save it.

Other than Power Off, you can also choose mute, brightness, and volume. You can also mix multiple type in one schedule, e.g. if you want to change the brightness and have the TV mute as well.


Now you have set the schedule set up. Once the schedule is created, it will be available to use, you can apply it on other screens. 


Also, please note the power on/off will power on/off the TV only, the OptiSigns Android Player will still be running. When you check the status on the portal, it will still show as online. However, since the TV is off, the color of the online status will become Orange, instead of Green, so you can tell the connected TV is powered off.



Note: The success of the use of this feature depends on many factors, including TV, players, firmware etc. We have tested on some popular brands, including Samsung, LG, Sony and Vizio. Currently we only support it on the OptiSigns Android players.
