To my Oregon WMR928 I have a USB-to-COM-port converter. That one seems to change device for unknown reason. It can happen during reboot or spontaneously. If it changes from /dev/ttyUSB0 to /dev/ttyUSB1 then Weewx stops. So I need to have a fixed device to use in weewx.conf
This page describes how to do it: http://hintshop.ludvig.co.nz/show/persistent-names-usb-serial-devices/ What I did was check the settings using "lsusb": [email protected]:~# lsusb Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 003: ID 1781:0c31 Multiple Vendors Bus 001 Device 004: ID 051d:0002 American Power Conversion Uninterruptible Power Supply *Bus 001 Device 005: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port* Bus 001 Device 002: ID 1a40:0101 TERMINUS TECHNOLOGY INC. Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub I created the file* /etc/udev/rules.d/99-usb-serial.rules* with the content: SUBSYSTEM=="tty", ATTRS{idVendor}=="067b", ATTRS{idProduct}=="2303", SYMLINK+="wmr928" (In the description they have "serial" too but I could not get that to work so I skipped it and it seems to do the trick anyway) The new device (link) will be */dev/wmr928* so change */etc/weewx/weewx.conf* for your station. Reboot Check that the new device is created and that Weewx works.. Reboot. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
