Yes, all the boards only probe the bus for sensor during power up. If you changed the 1-wire bus configuration, it is better recycle power, or power it off when changing sensors on 1-wire bus.
WC32 has Maxim made 1-wire bus master chip, that supposedly work for any sensor, even in parasite mode, if the sensor chip support that mode. However, in parasite mode, sensors work much slower, because during conversion, bus master must stop any activity on bus. WC8 does not support parasite mode, so that I can communicate with all sensors without waiting.
