[weewx-user] Re: rapidfire work on usb conected acurite display and 5-1 sensor?

[Jimmy r]

Thanks for the info, looks like using the bridge instead of USB has the 
same issue. I was using a windows computer for a few years with the kevin 
key's Acu-Link to Weather 
Underground 
http://kevin-key.blogspot.com/2013/11/app-that-reads-data-from-acu-link.html 
using this it was sending rapid fire, don't know how he had it dealing with 
the partial packets though but it worked. we had a bad lightening strike 
that took out a bunch of stuff in the house so i rebuilt using the 
raspberry instead of fixing the pc.

hi jimmy,

the acurite stations send partial packets.  unfortunately, wu rapidfire 
does not work with partial packets.

a solution has been discussed: make the wu restful service cache data.  see 
this issue for details:

https://github.com/weewx/weewx/issues/31

however, this solution has not yet been implemented.

Here is the URL http://munro.homeip.net:8080/ss or http://munro.homeip.net

It also looks like the max average wind speed and max gust values are 
interchanged when I compare with weewx Standard skin.

don't see any data returned. However when I connect the logger to a

you must specify the serial port in weewx.conf

every operating system has its own way of referring to serial ports.
on windows it is something like COM1

on linux systems with a serial-usb converter it is typically
/dev/ttyUSB0 or /dev/ttyUSB1

on some systems serial ports are /dev/ttyS0 or /dev/ttyS1

on some raspberry pi operating systems it is /dev/ttyAMA0

on odroid you might try /dev/ttySAC0 or /dev/ttySAC1

you can confirm it by looking at the output of dmesg

Thanks, Matthew,
There is still something that puzzles me as the original installation 
correctly gave /dev/ttyUSB0 as the correct serial port but it didn't 
work I changed it but that didn't work either and this morning, 
following your suggestion I looked in dmesg and saw USB0, reinstalled 
that and suddenly it works. (It may be the faulty connection that I had 
earlier).
The Windows software is also working but that is much too difficult to 
me (I have never worked with Windows) but now weewx works. I have 
changed the interval to 300 sec. (was 3000) so now I have to explore 
what is possible with a station that's much different from the TFA.
But thanks for all the help to get it working. Next step is to add a 
solar sensor as I have solar cells on my roof so measuring the solar 
intensity is useful.
