Dear All,
i just read the wohle thread, well there are of course thousand ways to
make sensors wireless ;)
According to 6lowpan, i would like to mention the Open Source Domotics
Group where i am member ;)
Basically the OSD-Groups aims to provide open and standards compliant
domotic solutions.

Well,
I made some progress on this.
I'd not yet used an arduino, programmed an avr or an xbee and got this
up in an evening and an afternoon. This is still not technically
relevant for the listserv as it's not on owfs, but if there is a way to
do that I'm game.
I used the following:

If I remember correctly it didn't choke on the writing itself. It'
Good info. I'm not sure why it should choke on that. There are examples of
sqlite for huge implementations, but I'd probably journal a log long before it
got to that size.
I'm fine with only one writer, and besides the database only locks for a few ms
when that happens.
I prefer the small, l

I started with sqlite and had to change it for a real database when it
became too slow after I had a few million readings in the dat
Looks like I wrote essentially the same thing, except using python except ruby
and sqlite instead in MySQL.

My current approach is to separate client/database and server/database
interactions. A client can still force a read if they wish. It's essentially a
cache, but I use it generally for all io, not just owfs. Logging just
automagically works using the read daemon that updates the database. It also

Great questions.
The simple way would be to bring the node up for a time long enough for the
owfs to see it and the polling/logging control script to read it. If the script
runs every 15 seconds, bring the node up for 30s and optimize from there.
The more intelligent way would be to bring it

A couple of questions
1 - How are you going to handle sleeping nodes, OWFS by its nature polls the
1-wire bus.
2 - You may want to consider sample frequencies, obvious I know the faster you
sample, the shorter the battery life.
Based on my own work with a combined atmega328 and RF module, and
From what I've read, the series 2 are capable of mesh networking and low power
mode, provided the unit is not a router or coordinator. I believe anything in a
mesh that is not an end node cannot go down to a low-power state, by virtue of
it needing to listen and relay from other nodes.

This project begs the question -- is it trivial to set up an ATTiny as a
1Wire UART bridge? I've a bunch of ATTiny85s on the Adafruit trinkets in
the mail along with some Xbees from Digikey (far cheaper). I'd love to
combine the two to wirelessly extend my 1Wire network.

Colin,
I've looked at Xbee as well, and indeed the feature set is rich, with meshing
being of interest.
Maybe I'll revisit it in the future using some of the lessons learned from my
SRF, XRF, RFu work.
Cheers

Thanks Stuart! Great, useful write-up.
I definitely looked at the XRF line, especially considering the pricepoint.
Ultimately the reason I chose XBee was that I anticipated users would want
to connect to their other Zigbee devices, and would therefore find an
on-board receiver useful for other thi
I've just documented my initial adventures into wireless sensor developments,
not using 1-wire based sensor yet but no reason why it couldn't.

Just my 2ct: Zigbee is closed and proprietary (but, well: it works here
and now!)

Hello all,
I've seen fragments here and there about wireless 1wire networks, but
nothing that sticks out as developed and/or inexpensive. Anybody have
success with IO over wireless, be it zigbee, sdr, or otherwise, to
something like an RPi?
Regards,
Colin
