Energy Consumption

[slartibartfast]

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.

The Amp doesn't consume much more at normal listening volumes than at idle

How much power do you think is needed for a moderate volume?
And I didn't play Rammstein when I measured it :

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

So I think it means that it is idle...

Again, it was not me who said that, but WiiM Support. So please don't ask me.

Understood.

My conclusion here. I will add a smart tap to Amp Pro and Amp. Now clear that our entire WiiM devices are consuming 15W.

New figures for my Amp
Playing 10-10.3W
Idle. 9.9-10.2W
Standby. 4.6-4.9W
Standby after 2 minutes 2.7-3.0W

With a USB Audio Interface plugged in the figures are 2W higher so I've unplugged that

Some devices (Sky boxes, Humax Aura, etc) have an option to go into deep/eco standby overnight. Maybe Wiim should consider this option.

I'm not sure if it is possible without IR remote controller to wake up device. I noticed that some streamers have bluetooth remote but Power button uses IR.

Those deep sleep options are a nightmare when the device is connected to the internet over powerline adaptors, as it can take as much as 2 minutes for the powerline adaptor to wake up again, and in that time the device has decided it has no internet access.

If power consumption bothers you just use smart plug. Turn it off when you’re not using it. You can turn on smart plug on your mobile device. It remind me someone I know who purchase Lamborghini just to complain how gas guzzler it was.

Hi all, just circling back to share some more details that confirm what slartibartfast is saying. The WiiM Amp Pro has two stages of standby. In the first stage, the Amp Pro places the amplifier component in idle mode, with standby power consumption at ~6W. After some time (about 2 minutes), the Amp Pro powers off the amplifier and codec components, reducing standby power consumption to ~3.5W.

If you have trigger out in the amp you can buy 12V 230V trigger. But you have to compare the cost with potential savings.

Just for the comparision I looked at power consumption of Yamaha MusicCast in the standby:

0.5 W (Network standby off / Bluetooth standby off), 1.9 W (Network standby on / Bluetooth standby on, Wi-Fi connection)

Oh, this definitely doesn't work well. At poweroff, it pings the 12V trigger and briefly wakes up the amp. On poweron, it wakes up the amp, plays a startup sound and the whole thing takes 20 seconds or so. And you also lose the network standby which should be doable with a lot less than 5W.

The comparison with a gas guzzler isn't apt because 80% of this power is wasted on standby. If the Lamborghini (or, more likely, the Spectre electric) drained a small amount overnight, people would 100% complain. Anyways, this is about being green.

@RyanWithWiim 2W would be acceptable. 5W is a bit much. I know that many Sonos's are the same, but people are complaining about idle power and they also have an amp & speaker to worry about.

I know people care about energy efficient but every time you add a piece of electronics it consume power and add to your monthly bill. As more people use energy, it will only get expensive. Getting power from power company they basically control how much they charge. Invest on solar panel especially if you consume a lot of power where it make sense than paying electric company. It hurts to pay solar panel in the beginning but long term you save.

I do have solar panels, but I'm also heavily electrified so it's not enough. Even if I could add more than I use, I'd rather send it to my neighbor replacing a little of the gas peaker plants than wasting it on standby electronics.

if that’s how it was design by wiim, what do you want them to do? I’m sure they will be more than happy by having using fraction of power if that was possible.

Well, maybe it wasn't a priority in the get-out-the-door stage, but maybe something could be done in the refinement stage.

Some are bothered by the inaudible last dBs of SINAD or jitter, some by an extra few watts 24 hours a day. Just making sure it's noticed.

I like the new clock face so have set it to be constantly on while in standby. Used to have it turned off after 5 mins with the old numbers readout.
Will give it a few days to see how much I look at it...

How could you configure the clock display after 5 minutes? I cannot remember having seen such a setting ever.

FYI the Sonos ERA 100 are actually below 2w when idling/standby (I measured them) and this is with network support and a power amp inside.
