Power Off

[ThatGuyThr]

Is there a function to schedule the CPU unit to power down so the monitor can hibernate? I would like to save energy during late night and early morning hours. Or other options to do so?

Hi @ThatGuyThr,

At DAKboard we call this Sleep Schedules, they are discussed in this support article:

I’ve updated the schedule in the device settings and unplugged my display twice and the off/on setting still isn’t working.

Hi @ThatGuyThr,

This could be if your display is not a CEC capable display, which means it cannot accept inbound controls via HDMI. It could also be if you are using a series of display adapters that removes the digital signal used by HDMI, for example converting HDMI to DVI to a display.

If either of these are the case, there will be no capability of the device to sleep the display unfortunately. Feel free to share with us the model number of the display and the equipment you are using here or emailing us at [email protected].

Hi Corey - Thank you for your feedback. The Display is a standard ViewSonic monitor (VA2759-SMH) and it’s connected directly with the HDMI cable from the CPU to the display. I notice the CPU never sleeps either, so the screen stays on our loop all night.

Hi @ThatGuyThr,

Thanks for the information there, I pulled up the details I was able to find and unfortunately don't see CEC supported by that monitor. The source that I used which has been fairly reliable in the past is here, and it would normally be located in the licenses group:

The Pi remaining on is expected, it is only tasked to sleep the screen. This is handled in this manner because the Pi cannot be turned on again.
