Sleep Timer doesn't work with Google Assistant

I think there’s likely a structural problem involved with how Google hands over streaming to Sonos, which is why it’s not a simple fix and why Sonos hasn’t done anything about it.

Many small problems like this provide clues that GA on Sonos does not directly play the source stream you requested like it would on a Google Home speaker or other Google Assistant speakers. Instead it passes that request to Sonos to fulfill.

That’s why GA on your Sonos speaker sometimes can’t find or play a stream that your Google Home speaker handles just fine, and why you need to separately authorize each streaming service on Sonos. I suspect that it’s also why Google can’t set a sleep timer on Sonos streaming, because Google washes its hands of the stream once it has passed to Sonos. 

Hi Doug

That seems like a sensible suggestion, only I don’t experience the other issues you report. This seems to be the only command that GA / Sonos struggles with. My surprise is that (a) reports suggest that Alexa doesn’t have the same problem; (b) the problem has been there for some time.

I wondered if this might provide a workaround?

You will encounter those issues - I guess you just haven’t gotten to them yet. It’s a Sonos requirement that you register music services in the Sonos app separately from Google Home before you can use them. And it’s well-documented here in these forums that GA on Sonos often produces different results from a Google Home speaker when asked to play a song title or stream. Experiment a little, and you’ll find examples.  

IFTTT won’t help with the missing sleep timer because it doesn’t have timers. However I use Olisto to set a fixed sleep timer for Sonos by voice command, since it does have timers as well as links to Sonos and Google Assistant. So I can say “Hey Google, sleep timer”, and it gives me a fixed 30-minute timer and then sends a Stop command to my Sonos speakers.

Doug, thanks, useful,  I was thinking of setting up a third party app as a work around. But Olisto doesn’t have links to Sonos or Google in its Channels now? 
Maybe it’s lost access to them since your post? Or maybe I am stupidly missing something obvious - not unknown!! 
(I’ve used Yonomi to successfully shuffle playlists via GA and Sonos but it doesn’t have sleep timer as an option for Sonos unfortunately) 

Still not working, and still no response from Sonos support. Way to go guys

Having the same issue on my new and freshly updated Sonos Move. Sad to see this critical voice feature still not working after a year of posts about it :(

I luckily received a One G2 and One SL for Christmas to use in my bedroom.  Now I find that the Sleep timer doesn’t work on Google Assistant.  I guess these will now be returned.  Not sure why Sonos doesn’t get this fixed.

Apparently, Sonos doesn’t care about what users post on this community forum. By the way, one possible solution is to use an app called Olisto. In is not easy to set up, but you can create workflows that does exactly what a sleep timer does.

I cannot believe a 3 year old thread has no reply from Sonos on such a critical failure.

I have 3 Sonos devices, and every few months I switch everything from Alexa to Google and vice versa.

Nothing works perfectly on this expensive system, and Sonos doesnt seem to care or even acknowledge anything.

I used to think Sonos was great, now I actively discourage anyone to buy it, its not production ready imo, far too many bugs that dont get fixed.
