Idle power consumption getting more concerning

It’s a reasonable question to ask.  Where do we find the official Bluesound figures for comparison?  I have been unable to track them down (although I haven’t spent much time trying).

I would like to second this!

It should be obvious that saving power is not just a feature request like any other.

The impact that Sonos can have here - on a global scale - would be gigantic!

So besides all ecological reasoning (which I also personally second) it would also have a significant marketing value for Sonos. On the other hand, missing out on this topic will very shortly turn into  no-go for an increasing number of customers.
 

From a technical perspective, I am pretty sure a bunch of skilled Sonos HW and SW engineers will be able to squeeze out a few watts from any existing designs standby power.

But even more important - make <1W standby power a design goal for every new generation device.

Sonos Management, anyone accepting the challenge?

The price of electricity is of course high now, but 52 US $ is right now the annual price in Denmark for having one single Beam 2 on idle standby without playing.

Most homes have many more Sonos products, so you can multiply this price.

Sonos is very expensive in standby power consumption.

I have written to Sonos several times over the years suggesting that they should introduce a deep sleep function on their products, but nothing has happened.

Personally, I also know people who do not want to buy a Beam 2 because of the high standby power consumption.

I switch the speakers off (using smart switches} when they aren't in use. 

Of course that is possible.

But that does not change anything wrt to this topic, because:

• how many people are aware?
• how many are willing to do it?
• how many use-case do not allow for completely switching power off?
• etc etc…

Bottom line: this feature is something Sonos should be implementing, it is worth it. Worth for the customers, worth for Sonos, worth for the environment.

Also, trying a calculate a rough estimate to show the impact Sonos could have.

The combined standby power of all Sonos product (and derived, like Ikea) in the field, also counting power used during delayed going into standby, is in the order of magnitude of a complete nuclear power plant!

Meaning, Sonos does the optimization and we can switch one power plant off, completely.

Wow.

There are probably technical reasons for the fact Sonos can not further lower power usage on their current models. They have however vowed to cut down the use on future models: https://www.digitaltrends.com/home-theater/sonos-net-zero-2040/

I do the same, without using smart switches:-).

I am pretty sure there are no technical reasons. There may be challenges, but that what engineering is all about, pushing boundaries.

I mean, just look at standby power of your cellphone, also „instant on“ multimedia, <<0.5watts, easily!

Look at competitors of Sonos,<<half of Sonos, easily!

I have been designing and developing embedded devices myself for many years, I am very confident significant reduction is possible for Sonos, if they want it.

Leave aside any third party verification for this, but does Bluesound publish the idle power used, in its spec the way typical audio kit does these days?
