Oregon Scientific WMR100 client for Linux/BSD/etc.

Supports

• Oregon Scientific WMR100
• Oregon Scientific WMR200
• Oregon Scientific RMS300A

Introduction

The WMR100/200 use a proprietary protocol for their USB connection.

It's very useful for enthusiasts running a headless Linux box to collect and analyze data from this link, but unfortunately the protocol isn't openly documented, nor are clients provided for this platform.

This simple C program handles the USB protocol of the WMR100, and translates to a JSON format, easy for parsing/analysing.

You can output to:

• stdout
• a file
• a zeromq socket

You'll need to setup the udev rules (see udev/README) if you want to run this not as root. This is due to how libhid accesses the USB ports.

Requisites

Packages:

• libhid-dev
• pkg-config
• libusb-dev
• libzmq-dev

Building

Run 'make'.

To install, copy wmr100 to your path.

One time install for osx

To keep the default HIDManager from taking the wmr100, run this once:

make setup_osx

If you want to use different software to read the wmr100 device, you should undo this by running make unsetup_osx and then reboot so that the HIDManager will take control of the device again.

Raspberry pi

To install on raspberry pi use this script:

https://github.com/think-free/pi-scripts/raw/master/InstallWmr100OnPi.sh

sudo apt-get install libusb-dev
# libzmq-dev
wget --no-check-certificate https://github.com/think-free/pi-packages/raw/master/libhid-0.2.16-rpi.tar.gz
tar xvf libhid-0.2.16-rpi.tar.gz
cd libhid-0.2.16
# ./configure --prefix=/
./configure --prefix=/usr
make
sudo make install
cd ..

# git clone https://github.com/barnybug/wmr100.git
cd wmr100
make


gcc wmr100.c -l hid

apt-get install fping

# /etc/crontab
#
# */20 *  * *  *  root  fping -q 8.8.8.8 || /sbin/reboot
#
#.

Usage

Run: ./wmr100

This will dump data to stdout. Each data lines begins with '*'.
