Whoops, I hit send too early…
OWFS servers can import devices from other OWFS instances on other machines. I
have found this to be a bit problematic on unreliable links though (this was a
couple of years ago, things may have improved since).
Regarding battery power, you’re not going to get Wifi and pure battery power to
last a reasonable amount of time. You could however get solar + battery to run
indefinitely.
I’m not sure about the construction where you are, but here in Australia, we
would get a cable outside by running it through the roof cavity, and then drill
through the eaves (normally made from fibreboard) to drop the cable outside.

For my pool solar controller, I use an HLK-RM04 module running OpenWRT and a
USB9097 1 wire master. If I was doing it again, I would an Orange Pi Zero or
simlar to reduce the cost.

Subject: [Owfs-developers] Arduino yun as wifi 1wire master
Lets 's start new.
I want a 1wire net outdoors. I want to avoid drilling hole into my brick walls.
So here the options:
1. squeeze cable beween window an wall
2. build wireless 1wire thingy e.g. RF or optical to connect through window
3. have a 1wire master like linkhube [1] sitting outdoors and connect throgh
wifi into my inhouse lan
[1] https://www.ibuttonlink.com/products/linkhube
1 is what I am doing and its bullshit. 2 is what I tried to e.g. using the new
I2C chip etc. blabla - I do not see how this could ever work. So 3 is now what
I am trying. Any other better ideas are welcome. I want to use wifi for one
1wire master outdoors but not for every single sensor. As FHEM can use an
Arduino as 1wire Master I came up with the Yun idea. Raspi Zero is fine too,
but someone needs to tell me how to set the software up, how to build the stuff
together. I don't want to run another instance of owfs on those devices as they
should act as master and not owfs servers.
Basically I could write a sketch for Arduino that emulates linkhube master and
then should be able to connect this to owserver but that would be quite some
effort given FHEM has already a solution for this...
The power btw. is no concern, if needed I can use a car battery... ;))
