Hi,
I already own a Sonos One, which I mostly play in the living room.
I was considering to buy another Sonos speaker for another room (terrace) and I was hesitant as to whether I should choose another Sonos One or a more recent Sonos Era 100.
The key new feature of the Sonos Era 100 for me is the ability to connect via Bluetooth, feature which was truly lacking with the Sonos One.
Ideally, I would buy a Sonos Era 100, connect to it via bluetooth, and play on all the house speakers (including the older non-bluetooth Sonos One) in a properly synchronised multiroom way. Are the speakers compatible enough, i.e.: is that supported?
Note that I would not need them to play as a stereo pair, as they will always be located in different rooms. If ever I wanted to benefit from single room stereo, I would then buy a second Sonos Era 100 to play both in stereo, together with the Sonos One in mono mode in a different room (would that work?).
Thanks for your support,
