Energy Consumption

[DRC]

No, but a light source for a room using the same wattage as a device doing nothing is a suitable comparator to how high that standby wattage is.

If Wiim devices were doing nothing then that would be true, but they remain connected to the internet and listening for a signal on the various inputs (HDMI, optical, etc) so that it is ready when you want to play music.

Less than 2 Watts, really, ich cant believe it, i measured ca. 5Watts, o.k the Meter is not calibraten and a consumer one. It is from Lidl. Measured an LED bulb the Meter indicates 4,6 Watt.

I measure the same on Ultra, 5W, independent of standby or not.

I agree with you. A Raspberry Pi server without a standby mode uses less than that.

Has anyone measured how many watts of instantaneous power consumption it takes to start up the WiiM when using a smart tap to completely shut down the WiiM?

Get kill watt meter and you let us know.

Used a Kill-a-Watt to measure my Ultra, wifi connected, RCA out, nothing connected to USB, US 110AC 60hz:

Startup (from unplugged): 6.1W peak
Idle: 5.4-5.6W
Standby: 5.4-5.6W
Streaming from Plex: 5.9W peak
Streaming from Amazon, awakened from Standby: 6.1W peak

I guess what surprises me is that the idle and standby power consumption is the same. (Standby does turn off my amps via 12v trigger so is still beneficial overall.)

The streaming - at least for Plex, it downloads the entirety of the song when started, spiking the consumption slightly, then maintained between 5.4-5.6W while playing the rest of the song. Similar with Amazon, there was a spike up to 6.1W, then back to 5.4-5.6W while playing.

Thanks for the great test.

I remember it was previously clarified in @onlyoneme's Pro test.

Also, I believe the support team mentioned it here.

WiiM Amp

Unfortunately not - some personal circumstances mean I now need to be away from home for a period. Talk about bad timing :( However, the WiiM Home website states "Plug your USB disk into the WiiM Amp and transform your home into a personal concert hall. Stream your digital music collection in...

@Smartplug ,
Thanks for the advice, I'm worried about the price of the kill watt meter being equivalent to years of Ultra's power consumption.

Not really. In that post they were talking about the Amp not the Ultra. A recent post literally said the Ultra consumed less than 2W in standby.

 

[justinhow]

WIIM need to inform us as to whether the FAQ is incorrect (that it is not actually <2w) and correct it, or explain why Ultra owners are not getting this in measured power consumption at home when in standby.
I also agree the 5w is quite a high standby level.
On my Denon AVR there is the option to set whether the standby mode powers the network electronics (so it can support Spotify Connect, get firmware updates etc) when in standby or not in which case standby power is about 0.5w. WIIM should do something similar perhaps.

You have misunderstood my explanation because I did not explain it well.

I was not referring to power consumption. I spoke about idling and standby.

"it's essential to note that the WiiM Amp does not currently support network standby mode."

But the post you replied to was about the Ultra not the Amp.

Yes, SoFluffy was surprised that Ultra's power consumption was the same in idle and standby. I believe that applies to all WiiM devices, not just Ultra. And I remember that was previously revealed in Onlyoneme's tests. (please search.)

This is probably true for all WiiMs, but the difference between idle and standby is unclear.

But @RyanWithWiim posted a table of energy consumption in the last few days showing the Ultra consuming less than 2W in standby. Something doesn't add up.

Yes, I agree.

I also find it odd that Ultra consumes less power than Pro plus; maybe there is some new technology in Ultra that has been optimized. But if that is the case, it doesn't explain why Amp Pro consumes significantly more power than Amp.

Regarding the Amp Pro another recent post showed actual measurements of 2-3W in standby which would be similar to the Amp. Something else doesn't add up

Also why say "less than 2W" for the Ultra when the Pro is listed as 1.67W?

But only the streamers, not the amps, right?
Otherwise I have to contradict you from my own experience/measurements.

As I said "probably", this is just my guess based on various posts on the forum so far.

Incidentally, did your amp measurements show a significant difference in power consumption while idle vs. standby?
(I think your one post mentioned power consumption during playback and standby, but I couldn't find one during idle.)

I remember when I measured my original Amp, I measured around 10W at idle, 5W when it first entered standby falling to 3W after a few minutes.

Hmmm, I may need to exclude Amp from this discussion though, but here @LucAce states that Amp's power consumption during operation was roughly 11W. I don't know why the power consumption is almost the same while Amp pro is idling and while Amp is running.

All of the data posted here is different and I am beginning to think it is silly to argue based on them.

"it's essential to note that the WiiM Amp does not currently support network standby mode."

How does the Amp automatically wake up from tidal connect etc if it doesn't have it's network enabled during standby?
