Oregon Scientific WMR100, WMR200 and RMS300 USB Protocol

Posted by Paul S at 19:15

Finally someone has published a detailed explanation of the Oregon Scientific USB weather station protocol used by the WMR-100, WMR-200, RMS-300 and others. Oregon Scientific does not share the information and is has been reverse engineered by a couple of people. Here are the definitions in German. Much easier to follow in English is the work of this guy. He also describes the WMR100N and WMRS200 driver for Mac OS X he is working on. The USB interface is a HID (device).

Prior to finding these links, the only option available was to run Windows XP software in a VMware instance and move the data into Mac OS X. Now there is hope for a native application to capture the data from the Oregon Scientific RMS-300.

Update: I use WeatherSnoop now on Mac OS X. I also found this open source package wfrog.
