M5Stack Timer Camera F (Fisheye, OV3660, ESP32, PSRAM)

This is the first thoroughly disappointing product from M5Stack. After having used the M5Core2 - absolute gem, and M5Stick Plus C - superb tiny ESP32 unit with fantastic hat expandability. The main downfall of the M5 Timer Cam (Fisheye version) is the thorough lack of documentation. Using the M5 burner software, one of the modules that sends an image every 30 s to the M5 cloud kind of works OK, but cannot be adjusted in terms of its functionality. The other modules (e.g. the UIFlow modules) have no easily recognisable function as I could not get them to work. The more promising Samba push firmware did not work either - could not get past authorising log in to my samba share (error messages on Serial monitor did not help). The only thing that I got to work is an Arduino project that provides a mini server with Video stream. Again, documentation where to change image quality (?ISO sensitivity) is nowhere to be found. The images look much more noisy compared to (for example) the Raspberry Pi Zero cam. The instructions on the official M5 website detailing how to use the Timer Cam with UIFlow are non-sensical and this module cannot be added. I think on the older UIFlow interface, it is listed among the platforms but has a line crossed through it (not available for adding).... A pity really, as in theory this could be nice compact and highly functionable unit with the usual benefits of the ESP32 system, built in small battery, camera, etc....
