There has always been a wireless version of the above-mentioned Kinesis Advantage 360, also running the ZMK firmware.
Before it, there were the open-source Dactyl variants that more or less copied the Kinesis. The original Dactyl [1] (2015) has a layout like the Kinesis but the more popular Dactyl Manuform variants have different thumb clusters. And people have been building them both with wired and wireless controllers.
The history is not complete without mentioning that Kinesis (Model 100 in 1992) in turn had copied the Maltron [2], designed by Lilian Malt in the 1970's.
