Thanks for your comments Matthias. It happened again today, same
channels I think. Could it be temperature related? The Pi etc is in
the loft and it was around 40C in there today, so the Pi would be
somewhat above that.

But do you really need 3.1p5 as you can easily get 3.1p4 from the repro

* Perform logic operations, setting outputs to devices based upon
temperatures read, etc
* Log values to database
* repeat.

I am trying to test out some code using the tester facility in owfs.conf
If I add

I can see that fake device. Looking at the documentation there is a way

Hi,
I build the owserver with following options:
./bootstrap
./configure --enable-usb
following messages showed up:
checking if usb support is enabled... yes
checking for LIBUSB... no

I just added a new page and it seems pretty easy to me to do that, but I
don't see any way to create a page hierarchy, is that possible? I think
we would need to group information to make it easily accessible.
btw I think this discussion is a fantastic move in the right direction,
currently
as well.
Now that I know about it I can work around it.
Thanks

Stefano,
I took your ex.py and modified it slightly to use a variable as the base
device name -

I am playing around with changing aliases via pyownet. I have had
instances where it all looks OK in python, but the httpd web page shows
it hasn't changed, but now I am seeing that it has changed on the top
level display but when I try to open a sensor the web page disappears
and httpd has
ent('sens%d' % j)
if __name__ == '__main__':
main()
