Just read VAD or VDD.
Note that the DS2438 must be powered. It is possible to power off the data
line, but that needs an external capacitor.

Hello,
I'm a very satisfied user of owfs for temperature measurements. Yet, I would
need now to read voltages and DC currents (1-15A range). For the later I got a
DS2438 and a Devicecraft hall-effect sensor. The resulting ~1A@12V sensitivity
would be satisfactory for me.
So, I have attached the D
Thanks. I've tried append error_level & error_print parameter, it still
doesn't work. I will try compile newer owfs version later and report the
result here.
BTW, if there are some tutorials about how to make use of
/sys/bus/w1//rw file?

Oh no, I fully agree!
The only way working with OWFS and DS9490 are hacks: fall back to older
versions improves
