Nothing has been announced but Sonos promises a minimum of five years once they quit selling a device. Not sure when that was but it wasn’t too long ago.

Play:1s were discontinued upon the announcement of the One SL in September 2019.

Thanks much. 5 years it is then :-P

At the least.  Some of the legacy products that were listed haven’t been sold in over a decade.

I just want to use my play 5’s for the purpose I bought them. I really could care less for voice integration or airplay. 
 

that said true to form and bang on cue one has ceased to power up. 

Contact Sonos support, they can usually help with out of warranty failures, maybe get it put in the trade-up pool even if it is too dead to do it directly.
