Reduce idle consumption energy level (currently around 5W)

Sonos devices on average consume about 5 watts each if idle. Having 5 sonos devices around this means 25 watts on average idle consumption. Over a year this is about (25x24hx365) 219 kwh. In Germany where 1 kwh is about 0,30 Euro Cent this then means about 70 Euro (about 100$) just to maintain an idle system. This is just too much and could easily be reduced. Looking at the environmental aspect this gets even more critical: There are around 2.5 million Sonos devices around. This adds up to 110,000,000 kwh or 110 million kwh.

I use a programmable remote power plug on my sonos Playbar, Sub and two rear "One" units so I can switch them off when I turn of the TV or Music, I also have another button to power of the TV. Other accessible sonos units in kitchen & bedroom are manually turned off when not required.

I would love to see a powersave feature.

Example: i usually dont need it between 01:00 and 05:00 o clock.

This could be very easilly configured.
Also wake up on press could be implemented in conjunction.

Hi,

I am considering to by Sonos products to cover my house. Roughly 10 units to make stereo pairs. It represents 50w (5wx10) 24/24h x 365 so about 70 EUR per year, 200 kg of CO2 over the year.
This is non sense. For most of the people, between work and night, the system is consuming power for nothing.
For now I am holding from buying. Reading at this post, over 4 years old now, it is clear that Sonos does not mind a penny of power saving request from customers.
Corporate responsibility is equal to 0 on that regard.
Denon Heos offers deep Stand By mode where the units are drawing only 0,6W, which is much better. Caveat: user has to put manually in deep sleep mode and to reactivate manually as well. So it is pretty useless. Not buying either.
Bluesound does not seem to do better...

Will need to spend extra money to buy smart plugs to program time when power can be cut off night and working hours). Considering the savings made it will take a few years to get the money back but at least, the little birds will love me...

Before totting up savings and little bird love, also factor in the cost in money and environment impact of faster equipment replacement arising from shorter service life arising from power cycling it. No one can say what this is, but arguably it may cancel out leaving the little birds in the same place as before.

On the other hand, not covering the whole house has a more definite impact on little birds.

This thread is 4 years old. The 5 watts thing is now under 3 watts for the Play:5 and One.

Wrong: my wattmeter on which my Play:1 is plugged says 5w, on idle status, after few hours of non use, not playing. I am in Europe with 230v power.
Si if Play:1 is above the listed specs from Sonos, I don't expect the Play:5 to be more accurate..

Kumar: I would be interested in statistics about the lifespan of PSU plug in all the time vs one being unplugged regularly.
Then we could compare the two and see if what is the less costly for the consumer between power savings + replacement vs plugged all the time...we are talking of years of ownership... so until my house is powered by solar panel, I will continue to care about power consumption of the devices which are always on.
Add up all the items in the house and all these tiny streams become rivers.

Add up all the items in the house and all these tiny streams become rivers.

See what I wrote earlier - this isn't available, but the phenomenon is known. So the only sure way to avoid rivers is to have less streams to start with. Or do something like what I do - turn off power to only those units that are not used on a daily basis and turn it on only when needed. Hopefully, this leaves me ahead on the equation with rooms where the music is needed once a week or less.
I also walk instead of using the car, as much as I can. Saves on doctor's bills as well that way. Isolated environmental gestures are usually not worth the trouble.

A simple switch can save the idle power use, this type is handy if the outlet isn't handy:

This type works well if the outlet is easy to reach:

Fancy and may well waste too much power you have ones like these:

Sonos may not have a lot of options to reduce idle power further - the processor, Ethernet and WiFi all need to be available so the system can be contacted and told to wake up when needed. That doesn't leave a lot that could be powered down on a connect, on a player or connect amp there are the amplifiers, but I believe they are already being powered down at idle from looking at my (Play 3 and 5) power measurements.

My bad: I tested again the power consumption of my Play:1 with another wattmeter and in idle mode it draws 2.7W. Much better. But still a few watts x times the speakers....
I am looking for remote controlled switch so that I can easily turn on and off the speakers according to the needs. So thks to Stanley for the links, I will have a look tonight!!

Ill do someThis thread is 4 years old. The 5 watts thing is now under 3 watts for the Play:5 and One.

Are you referring to updated software? Or because of new hardware (new Play One, new play 5). My devices are all the old models (3x play1, 2x play3 and 1x playbar). Was there an improvement from software and if yes, when did it happen?
