Then I'm happy to go on the bug-hunt.
Anyway, for my project I need an automation framework (not a GUI, just a
library) for 1-wire devices and Linux, with some things owfs itself doesn't
address, e.g. timers or grouping of 1-wire chips to "devices" - the goal here
is to uniquely identify "devices" instead of single chips and thus, allow
plug'n'work. I want to develop this in Tcl (that's why I'm after the
binding).
I don't know if you are interested in such a framework - it's a little off the
scope.

Great. I'll try out as soon the hardware arrives.

I'd expect the owtcl client to throw an error if the server is not reachable.
Am I correct? In that case, the automation framework could try to reconnect
every 10s or the like.

^^; I thought you already have that data, as this is the first question I'd
expect about any automation system. But Ok, I can measure it myself, too, no
hassle.

Ok, I will ask him on Tcl issues. The first thing on my nails is:
BUGS
Simultaneous work of several connections is not supported.
I really need multiple simultaneous connections for my application - who
doesn't? Is this a limitation of owlib (global data structures) or simply a
limitation in the owtcl wrapper? I would start with this bug if someone
guides me.
Kind regards
