Hi. I have two AcuRite 5n1 weather stations (model #'s 01536 and 02064),
each connected to it's own host computer and successfully running weewx 5.
Additionally
they both are setup to upload data to Wunderground, and generate an MQTT
topic. One also uploads to CWOP.
The host computers obtain sensor data via the USB data on the AcuRite
display units.
I would prefer to have both weather stations connected to a single host
computer, so I attempted to do this via the 'How to run multiple instances
of WeeWX' instructions in the link:
https://github.com/weewx/weewx/wiki/weewx-multi
Per the instructions I was able to configure weewx to successfully run the
stations with the same functionality as when they are connected to
dedicated hosts, albeit only one station can be connected to the host
computer at a time or I have the issues described below.
One station's configuration is named 'yardA' (the AcuRite model# 01536
unit) and the other is named 'yardB' (the AcuRite model #02064 unit).
With both stations plugged into the host computers USB ports:
1. When running both 'yardA' and 'yardB' at the same time, both stations
report data, but the data that is reported for both stations is exactly the
same.
2. When starting only 'yardA', weewx cannot 'pick' the model# 01536 unit
versus 'picking' the model# 02064 unit.
3. Likewise when starting only 'yardB', weewx cannot 'pick' the model#
02064 unit versus 'picking' the model# 01536 unit.
I have some suspicion the issue is being caused by using two of the exact
same AcuRite sensor units and both connected via USB.
I unplugged/re-plugged both units to USB and ran 'dmesg' to see if there is
any distinguishing device information between the two units. Based on this
simple test I'm not seeing anything specific that would let weewx
distinguish between these two AcuRite's as different devices (although I am
far from being knowledgeable on most anything weewx/linux/python/etc.)

I'm grateful in advance for suggestions anyone has on how make my multiple
AcuRite station setup work on a single host computer.
