I presume one would need a usb/1wire adaptor with that.

There are several options
- real usb 1wire host - pretty expensive
- usb serial+serial host
- use the internally available serial port (the console of the machine,
like with rpi) and use a serial 1wire host
- use some available gpio lines and do bit-banging
I went for the first because this

You do need some 1wire host for the AVR too.
If not, that means you plan for bit banging and a passive interface. Same
is possible with openwrt and a cheap router.
An other option is the arduino YUN, which is an arduino and a wifi module.
But the wifi module in there is a complete cheap home
I've no problem using a host chip like the ds2483, which I use all over the
place. I'd strongly prefer this to bitbanging.

I think serial host and bitbanging uc over xbee would work, but not for

What about a ds2480 into an atmega running owserver code 'emulation' over wifi
with an xbee or other wifi module?

I already use a Pi for the main gateway. It's big with enclosure and
necessitates a PS.
Think about having a sensor gateway at one point with remote modules in each
room. It would be crazy to have a Pi in each room. Ideally the remotes could be
battery powered.

Sure, wasn't sure what the driver was for wireless.
I think it's safe to say that things like
Yun, TP-Link, Pi, and BBB all play in the same arena so can be ruled out.

Silly me; atmega328 has i2c. I can use the 2483, but need to get data out.
Per the earlier conversation, can I mount the xbee serial /dev/AMA0 as a bus if
running in transparent? I believe this us possible, but limited to one bus.
This may have been previously discussed, but an API-mode

Yes! This is the 'glue' aspect I wrote of. If I know how to present data to
owfs, I can write my serial listener or API poller to configure it as owfs
would like.

it's up to you. a wifi xbee module is about twice as much as the tplink
router I have linked.
wifi, and tcpip are pretty complex protocols. to handle encryption, data
rates and the protocols, you must have some real cpu with some real
operating system. and once we have that, it will likely be
But the xbee is smaller and doesn't require hacking a router OS, which I'm not
interested in doing. It also doesn't scale for production. It's just not
designed for the job at all. With the openwrt router, what's the interface ?
Bitbanging gpio? Usb chip?
I have not seen reasonably priced
Neither me has seen reasonable hw for 6lowpan.
Production is all different, I admit. Have to consider mid/long term
availability of the components.
