The one thing I see missing is if you run it on a PIE and send it to another device over wifi then you eliminate any chance of thunder crashing a whole system and I mean everything in your home! Of course I live on the beach and we do have lot of storms! I just remember when I had a bolt land 200ft from the home and it still nocked everything and started from scratch again. since that time I do not have outdoor sensors! If power is a issue panels and a small battery is cheap and helps isolates one system from everything else! Why would you not want to isolate this system from other problems.... Seems the Pie is the cheapest way to do that! Why reinvent the wheel when that works and it is cheap.
Thanks for the numerous replies and suggestions to this topic! To make a long story short; I decided to not insist in a free/open solution for now and ordered a ethernet2wifi converter as I have an unused ethernet master around. For later I consider using a Raspi Zero W + level-shifting transistor + pull-up as this is an intressting option. Or may be an commercial master (USB, I2C, etc.) on the raspi.
For power, a solar panel was the solution I considered and still do. DC/DC converters are amazingly efficient nowadays... ;)
Drilling any hole - also in the proximity of the roof is not an option, as I currently live in an apartment block. Otherwise this can be a very nice solution. Actually I would prefer it, but then go outside with ethernet for a 1wire master as the 1wire could become verrry long otherwise (even though it might work).
owserver-deamon that would be needed to run on the Raspi Zero W e.g., means running 'owserver' binary, right?
The reason why I wanted to avoid running another instance of owserver in the first place, was power consumption and the fact that importing owfs instances from other machines might be a bit problematic (or connecting to other instances using the -s option). I read a few comments about this, don't know. Regarding power, I assumed the processors consumption (avr vs. arm, yun vs. raspi) and the number of processes running does matter, but if wifi dominates that might be wrong here. (And thus even an uno with wifi shield consumes the same.)
Thanks for all your comments and greetings

Its about 1 year since I played with Arduino 1wire slaves last. I have the impression a lot has happened on that field since (moat, etc.). Where should I start?
I would tend to go for moat onewirehub (instead of owslave), does that make sense? Is it supported by owfs as moat device or as the emulated devices are anyways? Can I implement more than 1 chip per Arduino, is that correct?
Any hints and experience shared would be helpful. Thanks and greetings!
