1. now 1 gpio only use for 1 sensor. maybe in future we will update it.
2. now can't use by GPIO39, GPIO40, GPIO41, but i think next update, we can enable to use it.
Interesting question! You're right, limited GPIOs are a pain. For the KC868-A16v3, check if multiplexing options exist in the software/firmware to utilize GPIO 39, 40, 41. Alternatively, consider a different sensor like the DHT22 for better accuracy, or explore addressable sensors on a single data line for future projects, a bit like navigating a challenging level in Moto X3M. No, you cannot connect DHT11 to same GPIO
