I have several Sonos speakers amps, all of the older generation (Play 3, Play 1, AMP).

They are all integrated into our domotics and power is automatically cut to the speakers when not in use.

This saves about 10 kWh of stand-by energy/year for the Sonos speakers alone (all our devices with stand-by current use are as far as possible automatically cut from power when not in use). 

 

I never had an issue with Sonos stuff with this configuration until I bought a set of Era 100’s to replace some Play 1’s.

When they are cut from the power, they loose their configuration.

They start up after resuming power with a blinking green LED and I have to add them to the app again, every time.

It looks like the configuration in the Era 100 is stored in volatile memory instead of non-volatile memory and can only survive a short power interruption.

 

It’s not a network issue (I’m into IT and run a professional Wifi network in my home with a seperate 2.4 GHz SSID for the Sonos stuff). I never have issues with the older Sonos speakers, only with the Era 100’s.

 

Everything runs on the latest firmware.

 

Does anybody experience similar issues? If yes, any solution?

If I can’t get this sorted out, I’ll return them and stick to my old Play 1’s.

 

No idea why they would lose configurations, but these devices, like all network devices, are designed to be left on 24/7.

Easy for me to say as where I live electricity is the cheapest on the planet (thanks to the hydro down the road).

Rebooting the Sonos device every day is going to hasten the deterioration of the internal storage due to the forced read/write.  SD storage has a limited number of read/write cycles, and once it hits that limit, you start losing the deteriorated areas of the card.  Just another reason why Sonos should be kept on whenever possible.

Sorry, but I’m running this kind of configuration for many many years on my older Sonos equipment.

Never had any issue whatsover.

As far as I know, flash storage is not sensitive concerning wear when only reading it. The speaker boots up and just needs to read it’s configuration.

By the way, these Era 100”s are new out of the box. So the flash memory (if Sonos uses flash) can’t be end of life due to to many read/write cycles.

 

And I’m energy conscious. When a device is not in use, I just cut the power. You would be surprised how many kWh/year are being used by sleeping devices when you monitor energy consumption of electrical devices in sleep state.

That’s one of the reasons I invested heavliy in domotics and energy management in my home.

If I want to play Sonos, I just hit the button in my domotics dashboard, which enables power to Sonos in the room I want, waits a specified amount of time to get it started up and starts playing my favorite radio station.

I’d get everything working and submit a diagnostic, note the number, get the Eras to drop their config again and do a second diagnostic.

Call support to get it looked into. You can try Chat but expect to go round a few times and get told to call in.
