Hi All,
I recently received a WMR89a and have been trying to get it to talk to
weewx. I have been reading through all the posts and discovered mwall's
driver in github.
I don't seem to have the unit talking to weewx as there are a lot of errors
in the syslog and was wondering if you could point me in the right
direction as to how to get it talking. I see from above that andr3id has
got it working in ubuntu so I'm hoping there is an easy fix.
I am running Ubuntu 16.04 on a VM hosted by ESXi 5.5. Having passed the USB
connection through to the VM I get the following when running lsusb:
root@weatherstation:/dev# lsusb
> Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
> Bus 002 Device 004: ID 0fde:ca0a Oregon Scientific
> Bus 002 Device 003: ID 0e0f:0002 VMware, Inc. Virtual USB Hub
> Bus 002 Device 002: ID 0e0f:0003 VMware, Inc. Virtual Mouse
> Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
However there was no /dev/ttyUSB0 automatically created. To do that I
followed the comments in mwalls code and andr3id's post:
sudo modprobe cp210x
> sudo sh -c 'echo 0fde ca0a > /sys/bus/usb-serial/drivers/cp210x/new_id'
I have then run the wee_config --reconfigure script setting the driver as
WMR89 with port /dev/ttyUSB0
I have then started weewx but get the following:
root@weatherstation:/dev# /etc/init.d/weewx start
> [ ok ] Starting weewx (via systemctl): weewx.service.
