Server Sleep and Wake on LAN

ScreenMachine-James, I confirm this is the same exact issue I’m having. Seems there are two issues: 1. The need (desire) for Roon to implement WOL on its Control apps, and 2. A problem whereas Roon prevents PC from going back to sleep once accessed from a remote Control app. I’ve posted detail of my experience with the sleep issue under the separate thread Roon is preventing Windows from sleeping

Sounds like you and I have a similar setup and are experiencing similar issues.

WOL is a good idea.

Several. Off the top of my head, suggestions about a “smart” replaygain type setting and addition of streaming radio stations (ability to add URLs).

10W = 10Wh per hour
10Wh * 24hours in a day = 240Wh
240Wh * 30days in a month = 7200Wh, or 7.2kWh

Let’s take the worst case situation, and assume you pay for electricity in Denmark, which has the highest price – a rate of €0.31 per kWh (wow that’s high!).

7.2kWh * €0.31 = €2.23

Sorry, but it doesn’t quickly add up.

Ok, I get it. You can’t implement WOL. Thanks for considering…

It can be implemented, but not in a way that we’d be happy with the experience. We do not want to encourage that.

You have a workaround by using WoL apps, and Nucleus does support it if you chose to go down that road.


It’s not about the price for me, but the useless power consumption. I think it’s a big design mistake. If there was an alternative for Roon this was the reason to leave. It’s like you guys living in the dark ages when it’s coming to energy consumption.


I agree, I think it’s a bit defeatist just to say people wouldn’t be happy with the experience when you’re in control of crafting it so that they are, but perhaps there’s some fundamental reason why not?

  • Server: “I’m not playing music, or anything, I’ll go to sleep.”
  • Control point: “hey server, wake up, I want to hear music.”

It seems so easy :grinning:


I guess it’s the “… or anything …” that’s the difficult part, as I understanding the Roon Core is constantly checking back with “Roon HQ” for metadata updates. Maybe that’s the part that Danny has concerns with?

As an aside … as a software architect / developer myself, I like to strive towards “smarter systems” I work in automated logistics and a hot topic these days is reduction in average and peak power demain … the later hits our clients hard in the pocket. See we now have “smart” systems that help to mitigate the power requirements … we do this by making sure that the larger electric motors don’t all spin up together … and at time of low utilisations the devices switch into low power states. Of course there are compromise … but our algorithms are turnable by the user to achieve the right balance for them.

Have you read this:

Roon has to work cleanly for all potential installations. Not just one where the Roon topology is fairly simple.

What about cases where there are more than 1 RoonCore on the same network? What about cases where the endpoints are different PCs, do they need a separate WOL? It sounds like a WOL manager is needed.

Upgrade to run ROCK on Intel NUC 8. gen. In mysetup the server consumes 2.9 watt during standby (no music played).

I have rarely read a more unhelpful and arrogant reply to a user request!

Mmm, is it that difficult to make WOL optional so it can be switched on under the right circumstances? It seems to me that the vast majority of us do not have multiple cores and would really like WOL which should be part and parcel of a music streamer. As many have already pointed out it works fine in JRiver.

Ps. I switched from Sonos to Roon because what the devs wanted and what I expected from the software had drifted apart so much that I no longer could do the things I wanted. Roon is nice and I sincerely hope I can stick with it a little longer: it does so many things well.

What are you referring to re:Sonos? I love Roon but there are things Sonos is really good at

If you are asking me what I do not like about Sonos, I do not know where to begin … Three things are pretty crucial though:

  1. No support for large collections
  2. No support for HD rips
  3. They actually abandoned most support for playlists based on users’ collections (putting their faith in on-line streaming)

Instead of support for their old user base, they went for those who like to scream back at their speakers and hold “meaningful” dialogues with them (no Alexa not this version of the song but XXXX …)

To me it sounds that Roon is afraid to implement WOL in the APP as it might not work on all related hardware which could lead to a lot of support questions towards Roon which they might not be able to solve. Hence WOL support has only been implemented into the Nucleus which is hardware they can control themselves.

Just my 50 cents…

Are you sure? I don’t think that the Nucleus products have WOL support, and neither do the Roon Remote software distributions (which would be the other half of the equation)

I thought so because @danny wrote: “You have a workaround by using WoL apps, and Nucleus does support it if you chose to go down that road.“

I stand corrected. The support is there in the BIOS of the Nucleus hardware, but needs a third party app running on your control devices to make use of it. The support is not in the Roon ecosystem of software.

Thank you for the clarification. That is similar to what my Mac Mini offers already today.
