A7s III:
USB connection works with live view, setting ISO, aperture and shutter speed. Shutter release also works and review with histogram is displayed even if you only shoot in RAW. This is probably thanks to the "Save PC image size" function (I'm not sure of the English name), which only sends a small JPG image (or original size) to the PC. With 1s interval, the releases are not exactly at the same time interval, with 1.5s it seems to be O.K.
The LRTimelapse mode does not work. Even if RAW+JPG is set in the camera, the app gives the error message that exactly this is not set and refuses further operation in the menu. Same with the next two models

A7 III:
USB connection works with live view, setting ISO, aperture and shutter speed. Shutter release also works and review with histogram is displayed with File RAW+JPG setting
WiFi working including LRTimelapse Mode
A7r III:
Same as A7 III but saving is obviously delayed by the USB connection. After the first release, the write LED lights up permanently and the indicator for the buffer also flashes permanently. Even without JPG transfer, I have to maintain a pause of at least 3.5s between shots with short exposure times. Without qdsrDashboard, 1 fps continuously is no problem with the 7r III. Interestingly, this is no longer a problem with longer exposure times - 10.5s Interval at 10s exposure time works fine.
