Letting the server machine sleep (macOS)

Beta Community DVR Beta
#82

I’m noticing that the display attached to my Mac Mini that runs the DVR no longer seems to sleep. Is this possibly a side effect of the changes made here?

#83

Don’t think so… you can run the following command in terminal to see what’s keeping the display active:

pmset -g assertions

#84

I tried to let my 2010 Mac Mini sleep and it missed two recordings today. I see in the log that they were scheduled but did not start.

For the second recording, I launched Channels on ATV while the program I wanted to record was still on. The Mac Mini woke and started the at that time.

Any ideas on what to check? I’m running 10.10.5 but could upgrade to 10.11.

#85

In order to enable this, you have to run the following commands in Terminal:

cd ~/channels-dvr
curl -fo install.sh https://getchannels.com/dvr/install-darwin.sh
./install.sh --wake-helper

It will ask for your password, and setup a sudo helper for the DVR to be able to wake up when it needs to.

#86

Thanks. I missed that in your earlier post!

#89

soo

I ran that script and now my iMac won’t sleep at all… Screen is not turning off after 5 minutes like it’s supposed to. Neither is the screen saver. Heck, I won’t even go to sleep manually when using “suspend activity” in the Apple menu. Screen goes black and them comes back right up.

I need help.

#90

Can you run pmset -g assertions in Terminal.app and post the output?

#91

I have a Macbook Pro that I am using as a server and have experienced crashes during the early morning hours. I suspect that it is related to Channels DVR and Bonjour.

When the Bonjour box is not check I did not have crashes for several days. Bonjour is working as expected for waking for recordings and the computer will sleep. Although, it may take longer to sleep than the time specified energy savings.

It is far from scientific at this point, but I did copy some logs that I captured this morning. Perhaps someone may have encountered a similar problem? Any suggestions on how I may proceed in isolating the cause of the crashes? I will email an additional log.

#93

When you say crashes, can you elaborate on what you’re seeing?

#94

The computer will not respond. The screen is black and I have to hold the power button before it reboots.

#95

So,

Any updates? My computer still is an insomniac… getting frustrating… can I easily uninstall the “wake to record” script?

thanks

#96

Sorry, haven’t had a chance to dig into this.

You can uninstall by running this command:

sudo rm /etc/sudoers.d/channels-dvr

#97

You can also try restarting the DVR via the mac menu at the top of the screen (next to clock/wifi), by clicking the TV icon and selecting Restart.

The DVR should only be preventing sleep when it’s busy… next time you try to sleep it and it refuses, run this command in terminal and post the results:

curl 127.0.0.1:8089/dvr

#98

Okay, and just to confirm, if you run pmset -g assertions again it says “DVR Engine Activity”?

I would expect that when the curl command says “busy”:false that the assertion should not be present either. Sounds like things are getting out of sync somewhere.

#100

Here, I ran the Assertions command again :

#101

I have now uninstalled the script. I will wait untill you get more time to look into this. Tell me if you need me to run it again to help you trouble shoot it.

I will now let my computer sleep and miss a few recordings.

#102

Computer still won’t sleep… don’t know what happened. Maybe it did not uninstalled properly? It was fine before I installed it…

would appreciate some help

#103

Hmm, I see why… the part you uninstalled is for waking up the Mac to make a recording.

But the issue is in the other half, which is inside the DVR and prevents it from sleeping.

What does this command output:

pmset -g assertions | grep -A1 channels-dvr; curl 127.0.0.1:8089/dvr
