Hi Steve,

I have only tested a single device.
But I think, it must work.
Also I have seen no jumps (missing codes) on slow rising or falling of the temperature. Means, it look true monotonous.


If you want to use more devices:

1.
use separate pins for every device.

2.
use an analog switch (74HC4051) to select a device.

3.
use the DS1820, which can be separate addressed on the same wire.
