What’s the logic behind not having a turn off button?

There is one thing - that comparing the standby status for a TV may not be apples to apples when compared to that of a networked player like Sonos. There is far less to be done in a TV to move from standby to ON in the time expected by users of today compared to what has to be done for Sonos, because of which more things need to remain ON in Sonos even when in standby mode.

Sonos is a wireless audio system. If you have to turn it on every time you enter the room, it would just defeat the purpose of the system, especially if you like to use voice control to start playing music, like I do.

I’m not following you, can you explain more?

Sonos speakers do not have a standby mode.  They have a low power mode.  A speaker may not be playing but still participating in SonosNet.  And of course, if you powered off your wired device in a SonosNet setup then the whole system would disappear.  

Even in WiFi mode, Sonos uses direct routing between devices where that would optimise performance.

I have already mentioned that every complete power off and on gives your router a chance to screw up IP addresses.  As a multi-device system Sonos is more vulnerable to IP address conflicts than single devices.

Controller devices latch onto a particular speaker (called the ‘associated product’) with which to communicate.  The system is designed to operate as a unified entity, not to have bits regularly removed and added back in, forcing reconfiguration and potentially sub-optimal performance..

The comparison with a standalone device like a television seems to me totally inappropriate.

@Bumper Can you tell me how my post is unclear to you? I like to have music start without hesitation when I enter the room and group speakers that are in a different part of the house. This is impossible if you have to start up the system manually every time you want to use it. Very 1995 in my opinion....

And I would seriously consider not turning off the lights when I left a room if it was going to take more than 3 seconds to put them on again when I returned.

The answer is for Sonos to find ways to minimise standby power consumption while still remaining available for play as it does today; perhaps all radios in each unit except one can be turned off. 0.5 watts in standby mode may not be possible but something better than today ought to be.

Hopefully these aspects get as much attention as the controller eye candy changes.

Lol. Fair point. But it would also depend on the time I was to be away. Even if it took 15 seconds, I would turn them off for a long absence or even just overnight. Except perhaps for the one in the bathroom in such a case:-).

The TV standby is easy, power down all but the remote control circuitry and put up with long slow boot times. Which is why many brands offer a much higher power quick boot mode that keeps the CPU alive.

On Sonos there ins’t a remote control circuit as such, so all they can do is switch to low power mode.

You can duplicate the TV low power mode by simply adding a remote controlled smart power switch. Boot time will be a PITA but you’ll save all but a fraction of a watt for the smart switch. Old school you could just use a power strip. :-)
