Hi everyone,

I needed to change my network router as we have a new TP Link Deco mesh system.

This required me to set up my Sonos network again.

I set up my Playbar, Play 1 and Synfonisk speaker on the same Sonos system using the S1 app.

So far so good.

I then wanted to set up my Roam speaker. So I used the new Sonos app for this, and set up a new system as the S1 isn’t compatible with this speaker.

I then (foolishly) decided that I wanted to add my Play 1 speaker to the same system as the Roam, as the Play 1 is compatible with the S1 and new Sonos apps. So I went through the upgrade process for the Play 1 and added it to the system associated with the new Sonos app.

Then I realised this actually wasn’t what I really wanted after all.

I therefore followed the ‘downgrade’ process in the new Sonos app, and downgraded the Play 1 to be compatible with the S1 app again.

However, I can’t now add it into the S1 app as I keep getting the same ‘Sonos app needs updating’ message that other people have mentioned in other threads.

The S1 app is not ‘seeing’ my Play 1, even though I’ve downgraded it, and have factory reset it a number of times.

Anyone able to help me add the Play 1 back to the S1 system again, please?

I’m running the latest version of all the Sonos apps on my iPhone.

If you temporarily wire the Play:1 to your Deco, the S1 system should hopefully see it again for you to add it back to the system.


Hi Mr T,

Thanks for your answer.

However, the Play 1 is connected to the Deco system and it doesn’t ‘see it’.

I know that other people have suggested connecting Sonos speakers to the router or mesh ‘nodes’ to speed up the setting up of systems etc. But in my case, this doesn’t work.

If you’ve any other ideas, please share them.


Did the downgrade process to S1 complete successfully? Did you see any confirmation?

What is the status of the LED on the Play:1? It should be flashing green.


Hi Mr T,

Thanjs for your further reply

The downgrade process, as far as I could tell, completed successfully. The app indicated it was done and the light on the Play 1 was flashing green. 
 

The Play 1 is just not being ‘seen' by the S1 app. 
 

Very frustrating!
