Hello,

regardless which timeouts I set, and how.

DS9097U I tried recently. Odd. Any idea what's different with DS2482-800?

A 4m pole made of wood will without much doubt *never* been hit by

is very unlikely)

Great, the alarm bug is away, too. The problem with reading uncached through

Simultaneous conversion is not possible when on parasitic power. That's a
limitation of the hardware. If OWW works, it just doesn't use simultaneous
conversion.

Sampling 19 temperature sensors one-by-one takes up to 19 seconds. This
is due to the lengthy A/D conversion process.

No, but it's the only way you can do a simultaneous conversion for all
chips, and this 19 times faster if you have 19 chips.
You cannot do a simultaneous conversion
