Hi!!!
Before some days i bought 3 witty pi 3 mini. When i power it on from the usb port the white led flashing not the red one, so far so good but it can turn on the raspberry even if i press the button on it. I check it with an other one and everything works perfect. What Can i do???

If you are testing it with USB port on your PC, better not to do so, because the USB port on PC may not deliver enough current to boot your Pi.
Witty Pi use MOSFET to control Pi's power, MOSFET has internal resistor, which may vary from unit to unit. Also the connecting resistor between Witty Pi and Raspberry Pi may vary from case to case. When the power source is not competent, it is possible to see different behavior on different unit.
If you are already using a good power supply for such testing, and one unit can boot up while the other can not, then it is indeed possible that one is faulty/damaged. In such case it is no longer a topic in this forum. Btw, considering Witty Pi 3 Mini has been discontinued for almost 2 years, I don't think it can be replaced now.
