! OWW-OpenWrt



This page is for information on getting oww to work on openwrt.

!! Background

OWW stands for one wire weather and is a weather monitoring system based around the Dallas one-wire protocol and the Dallas example weather station kit available from aag

The oww software allows for remote monitoring of the device over tcp so you can get the wind speed & temp at your poor freezing remote wireless node on the hill !



! OS version used

openwrt RC5 (2.4 kernel)



! Hardware used

wl-500gP with dallas one wire weather station kit and rs232 adaptor

but any ap with 3.3v serial, openwrt support and enough flash space can be used.

[melb_ap] 8/7/08 : I'm currently working on this project to get the dallas weather sensors running at various node locations.



THE NLSU2 unslung site has the oww software available compiled for openwrt and the wl-500gP but I haven't quite got it to work just yet.



I have a max232 and the dallas rs232 interface connected to the wl-500gP

but running ./owwnogui -i in /opt/bin just hangs the router at present.



I've verified it works ok on a pc with the AAG software which was also handy to get the sensor serials required for oww's devices config.

Trying a usb to serial adaptor atm, note serial is /dev/usb/tts/0



Yah we have data 



01/01/00 , 00:08:29 ,    20.1,���¯���¿���½C   ,    0.00,  MPH,       WNW   ,292.5  , 13    , 0.00, inches



After much work and some help from some other members I have a working configuration.



If your looking at this project , use the RS232 to one wire adaptor and the A-Ten USB to serial converter.



I'm not aware of openwrt support for the USB to one wire device.





And for time sync , just use rdate once you've set the correct time zone.
