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. 

I understand that I don't 'need' 1wire for many purposes, but I like the 
flexibility, and am convinced that without too much pain I can get an attiny85 
to do the legwork and make it happen. The price point is about $17, which 
(given other options) I find quite reasonable. 

I'll let you know how I get on. Please do the same.
