I don't know if it's related, but I also have two DS2760's (Hobby
Boards moisture meters) which owfs sometimes gets readi

Is it easy to add the reset in owserver as well? I'll gladly tr
Looking through the oww source code, it looks like they reset all the
parameters before every measurement. I wonder if the flaky sensors
have an intermittent connection and do unscheduled power-on-resets?

Hi,

Strange. I have one of those, too; it goes offline when the ambient
temperature rises beyond 25°C or so. :-/

I have similar problems with DS2450.
I have 3 DS2450S connected to my network (CO2-level, Barometric preasure
and a Light sensor). On two of the chips I measure the VDD level on my
network.
On one of the chips (always the same) I get 0V as a result when
measuring the VDD level (that is approx

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.
Kind regards

You mean DS2450? Both work in oww, but only one works in owfs. So it
looks like the adc stuff in owfs has a problem.

So one DS2405 works well, and the other not?

I have two AAG anemometers, both DS2450 based. Eight reed switches
are organised in such a way that each of the four inputs to the AD
converter either is (roughly) 0V, 2.5V or 5V and the combination of
the four levels will identify one of 16 bearings of the vane (whose
magnet will connect the swit
