you can use rs-232 to rs422 converters + rs232 to ow converter + many usb-serial converters
rs422 allow 1500meters of distance with 4 wires, add a rs232-rs422 converter near to usb serial converter near to onewire line, add a rs422-rs232 converter and the rs232-ow converter this should work without problem, but it's not wireless :P 2014-01-27 Colin Reese <colin.re...@gmail.com>: > Easiest, perhaps.
