Yeah... only the 12-speed disc brake shifters support wireless shifting, but even then, the derailleurs are still wired to the battery.
I am in the process of writing a page on the two wiring options for rim brake handlebars (
https://goodshifting.com/installatio...fters-by-wire/ user: goodshifting pass: di2test), but it's not great.
For a fully wireless bike, SRAM is definitely the best option at this time.
(I'm not sure there are wireless SRAM rim brake shifters (?)).
My commuter bike is currently moving from 11-speed 6870 Di2 to 1x 105 Di2. Since it's a rim brake bike, it takes some messing around with wires and junctions. Especially since the frame isn't made with Di2 in mind.. there is no way to run two wires (shifters + RD) to the battery on this frame, and there are no openings between the BB shell and the down tube / seat stay.
I ended up putting a 4-port junction (JC304) in the down tube and connecting the shifters and RD to that.. and then I run a single wire into the frame to the battery.
