SO SO disappointed with SONOS, APPS absolutely useless, which makes the system useless

You should be using the S1 software. It sounds like the Playbar somehow got updated to S2. I suggest you:

• factory reset the Playbar
• remove any S2 controller apps, and reinstall the S1 app
• when the app starts tell it to connect to an existing system
• check that the Play:5s and ZP90 are visible
• add the Playbar to the system and, hopefully, it should downgrade itself to S1

Unless you sit there as a personal DHCP server waiting to respond to requests I don’t see how. Sonos units cannot be configured with static addresses. Or did you simply mean that you reserve IPs for all your devices?

Ratty,

I do use reserve addressing, as you are right, it is not possible to assign an address to a sonos device any other way. I have several sonos devices, bridge cr200, zp90, 2 x play 5, and soundbar. The play 5 are switched off, as they don’t work, and the cr200 is sat trying to update itself, as it has been for the last year, but out of sight, out of mind. It’s in a cupboard along with my music server. 

On christmas day wife wanted music whilst having dinner, so I thought, well better try a play 5, and switched it on. when it came up, it appeared in the S1 app on iphone, and wanted to update. Unable to use until it updated, so gave it a try. After this update completed, previous ones had not, then it was available and ready to use. To my surprise it worked. I then switched on other play 5 and after update that also worked. I have not been able to use the play 5 for over a year as they were borked by an update that was unasked for.

I’m a happy bunny, but still would like to be able to refuse updates and still have my kit working. None of the IT OS manufacturers force updates on you, so why does sonos?

Too right. My working system no longer works because it kept nagging to update to S2 and someone in the building presses that button to do so. Now all our Crestron touch panels won’t control Sonos. So much for us choosing the system because of the Crestron/Sonos partnership.

Downgrade to S1? The documented method of factory reset doesn’t downgrade the OS from S2 to S1 on any of my devices. And even if it did, how am I going to stop someone random pressing that nagging update button & having this problem occur again?

Upgrade the Crestron controller to S2? No, Crestron doesn’t support that despite its partnership with Sonos.

It doesn’t. You can disable the regular check that the system makes for firmware updates, via Settings/System/System Updates.

However you’d also have to take parallel steps to prevent automatic controller app updates. By default iOS and Android devices autoupdate their installed apps. Since controllers and player firmware have to be matched the update of one may require the update of the other before the system will work.

As an aside, most cases of “borking by an update” are typically caused by a duplicated IP after the units reboot post update. 

So, the system was able to update entirely to S2. And because a third party external controller, about which the system had no knowledge, is unable to stay in step it’s somehow Sonos’ fault?

The system may not have had knowledge of it, but the company certainly did. Crestron & Sonos had a working partnership, which was openly advertised as a selling point for both their systems. And it was on this basis that we invested in Sonos. So why didn’t Sonos the company make sure that Sonos the system know about this partnership?

The problem would not have been a problem if the Sonos system didn’t keep nagging to update. The user should be given the options of Upgrade, Remind Me Later or Don’t Remind Me Again. 

Systems are never constrained by controllers. Controllers are entirely optional; they can come and go at any time.

It strikes me that your complaint ought to be levelled at Crestron as you’re their customer.

Mine doesn’t disable the regular check. I only have an option for automatic update or not. It still checks and it still nags even if you disable the automatic update. 

That was in response to the previous poster’s

None of the IT OS manufacturers force updates on you, so why does sonos?

I don’t quite understand this. I as the customer shouldn’t be thinking Controllers come and go. Before I used Sonos, I didn’t even know what a Sonos Controller was. Sonos advertised themselves as compatible with Crestron. Crestron advertised themselves as compatible with Sonos. Now they don’t work. Crestron didn’t change. Sonos changed. I don’t see how that’s a Crestron problem.

I have another thread where I’ve asked for advice, but one problem I have is that should I actually manage to downgrade my system to S1, what’s going to stop a random “helpful” user in the building from pressing the nagging Update button on the Sonos Controller app on a Crestron screen? Why can’t I (as the system admin) turn that nagging notification off?
