Hi @blaisemail, welcome to the Sonos Community!
From what I can see on my end, we don’t have any ETA for Google Assistant (GA) being supported on the Era 100s: I can’t say when or if GA will come to these speakers.
You can still control the Era 100 with another Sonos speaker that support GA or if you have a Google device, such as a Google Home, you can use that to send commands to the Era. This support article explains how to use a Google device to control Sonos.
I hope this information helps!
