Bus 001 Device 004: ID 0fde:ca01

but recognized by the kernel in the following way:

usb 1-5.1: new low speed USB device using ehci_hcd and address 11

The WMRS 200 can be used under Linux with the open source software WeeWX ( This Python program can read out the data of the weather station, store them and create charts and HTML web pages out of them.
