Hi guys,
For quite some time I had been running weewx version 2.3.6 with my FineOffset weather station.. I have a USB hub with PPPS and had added a small cludge in wxengine.py to power cycle the base station whenever the USB locked up, and it did this when needed, sometimes it would go 10 or more days without a reset. I have just in the last few days upgraded everything, Pi firmware, apt-get upgrade etc ... And upgraded weewx. I read through the change log and found that weewx had built in support now to switch the PPPS usb hub, so I configured it for that.. Didn't work.. Everything runs until suddenly I get spurious records that do not trigger weewx to reset the USB port though. I have the following in my /etc/weewx/weewx.conf:
[FineOffsetUSB]
# This section is for the Fine Offset series of weather stations.
# The station model, e.g., WH1080, WS1090, WS2080, WH3081
model = WH1080
# The polling mode can be PERIODIC or ADAPTIVE
polling_mode = ADAPTIVE
# How often to poll the station for data, in seconds
polling_interval = 60
# The pressure calibration offset, in hPa (millibars)
pressure_offset = 0
# The driver to use
driver = weewx.drivers.fousb
station_interval = 60
power_cycle_hub = 001:005
power_cycle_port = 1
I don't have debug mode turned on at this point, but will for the next time it happens, but here is the log of whats happening as far as I have seen it as you will see weewx is crashing without even issuing traceback output the first time around and it's restarted by my restart script I use:

Hope this helps... Thanks in advance for any suggestions..

the usb communication is failing before weewx can even get the archive interval from the station.
power cycle the station. be sure that your batteries are fresh. if you are powering the console only via usb, be sure that the usb hub provides sufficient power.
also, you should not use ADAPTIVE mode - that will increase greatly the chance of a usb lockup. use PERIODIC instead.

Hi mwall,
It's powered just by USB specifically so the USB hub can power cycle it, and unless something in the hub has died at the exact same time I upgraded the Pi firmware then yeah, something fishy... I am pretty sure I switched from PERIODIC to ADAPTIVE back in the earlier versions because ADAPTIVE was meant to be nicer to the USB bus etc... Or maybe at the time I changed, found it worse on PERIODIC and switched back? Cannot remember, that was a couple of years ago... I have tossed in another os.system call to the usb power switching program I have always used at the error message it failed at, hopefully that will clear things up... Funnily enough it hasn't locked up since I started this thread :/ I am going to stop using the base station pretty soon, I have a 433MHz receiver which I will soon attach to the Pi and do things that way... Thanks m for getting back to me with your suggestion! I shall change to PERIODIC and see how that goes :)

Also just remembered, I am getting spurious readings, seems to almost be at the same time of day, will look at that tomorrow, which is something I never had before... Really wishing I didn't do a firmware upgrade now.... At least I would have a better idea what was going wrong...

After burning a few SD cards on my B+, I've switched to a USB hard drive and started to notice similar problems to those listed in this thread below.
Namely: "TypeError: unsupported operand type(s) for *: 'NoneType' and 'int"
I invariably get the problem after powerup but I've discovered that rebooting sorts the problem out, latest occurance took 2 reboots after I moved from ethernet cable to USB wifi. I now have fully populated USB ports on the B+ so I suppose it's not too surprising that I get some conflicts. It may well be the Fine Offset that causes the problem, but I have 3 other devices on USB that work fine so thought it best to note it. I thought that I'd mention this as there was a comment in another thread about the Fine Offest USB driver being re-written.

can you post the actual log of the error to help identify the cause? Are you using nick's gauges by any chance - there used to be errors in the gauges when things like windspeed or wind direction were None - the condition was not handled correctly.

Sorry, I'm not sure how / if you can post code blocks here so I've listed the Weewx startup lines from syslog. For me the problem only exists at powerup, rebooting normally clears it:

The log snippet should give matthew something to work with!

Sorry, I'm not sure how / if you can post code blocks here so I've listed the Weewx startup lines from syslog. For me the problem only exists at powerup, rebooting normally clears it:
cameron,
the log was what we needed - everyone already has the code :)
change the station's archive interval to 5 minutes instead of 60 minutes. with weewx *not* running, do this:
sudo wee_config_device --set-interval 5
change the record generation to software. do this at the appropriate place in weewx.conf:
[StdArchive]
record_generation = software
those two changes will significantly reduce the amount of usb communication and make your setup less prone to failure.
also, try using a powered hub. try running the fine offset station when nothing else is connected to the pi. if it works better in either of those configurations, then you know you have a hardware issue.

Thanks for the pointers, I've implemented the changes as suggested and also changed weewx.conf so that "polling_interval = 300", I'm assuming that this will match the set interval of 5 mins. By coincidence it all started fine on powerup this time before I'd made the software changes! One thing that I had done was to use different USB ports for each device as part of a general cable tidy up.

leave polling interval at 60 seconds.
it was the hardware record generation, especially with archive interval of 60 seconds, that was causing most of the usb chatter.
