Thanks all - the suggested config changes appear to be working well. Much appreciated. Cheers Andrew -- You received this message because you are subscribed to the Google Groups "weewx-user" group.

Thanks Matt... I made the suggested change but still get essentially the same error: Mar 30 21:57:59 raspberrypi weewx[7145]: File "/usr/share/weewx/user/swb.py", line 52, in Mar 30 21:57:59 raspberrypi weewx[7145]: weewx.accum.extract_dict['grid_energy'] = weewx.accum.Accum.extract_sum Mar 30 21:57:59 raspberrypi weewx[7145]: TypeError: 'NoneType' object does not support item assignment Mar 30 21:57:59 raspberrypi weewx[7145]: Exiting. ...any other ideas? Is there a way to drop this out of swb.py and add to the config file as Tom suggests?

[weewx-user] Problem with weewx-swb 0.4 under 3.7.0 and 3.7.1
Hi I'm running weewx installed from the .deb, and since upgrading from 3.6.2 (initially to 3.7.0 and now 3.7.1) I've had problems getting weewx-swb to run. I'm running 2 instances of weewx (one for my OWFS-based weather station, and the second running SWB v0.4), with separate config files. My weewx-swb config file has been upgraded. This setup has performed well through previous upgrades, but when I upgraded to 3.7.0 I began seeing errors. These have persisted now that I've upgraded to 3.7.1. My log shows the following errors: Mar 29 20:04:00 raspberrypi weewx[6163]: engine: Initializing weewx version 3.7.1 Mar 29 20:04:00 raspberrypi weewx[6163]: engine: Using Python 2.7.3 (default, Jun 22 2016, 03:14:32) #012[GCC 4.6.3] Mar 29 20:04:00 raspberrypi weewx[6163]: engine: Platform Linux-4.4.38+-armv6l-with-debian-7.11 Mar 29 20:04:00 raspberrypi weewx[6163]: engine: Locale is 'en_AU.UTF-8' Mar 29 20:04:00 raspberrypi weewx[6163]: engine: pid file is /var/run/weewx-swb.pid Mar 29 20:04:01 raspberrypi weewx[6167]: engine: Using configuration file /etc/weewx/weewx-swb.conf Mar 29 20:04:01 raspberrypi weewx[6167]: engine: Loading station type SunnyWebBox (user.swb) Mar 29 20:04:01 raspberrypi weewx[6167]: engine: Caught unrecoverable exception in engine: Mar 29 20:04:01 raspberrypi weewx[6167]: type object 'Accum' has no attribute 'sum_extract' Mar 29 20:04:01 raspberrypi weewx[6167]: Traceback (most recent call last): Mar 29 20:04:01 raspberrypi weewx[6167]: File "/usr/share/weewx/weewx/engine.py", line 865, in main Mar 29 20:04:01 raspberrypi weewx[6167]: engine = engine_class(config_dict) Mar 29 20:04:01 raspberrypi weewx[6167]: File "/usr/share/weewx/weewx/engine.py", line 71, in __init__ Mar 29 20:04:01 raspberrypi weewx[6167]: self.setupStation(config_dict) Mar 29 20:04:01 raspberrypi weewx[6167]: File "/usr/share/weewx/weewx/engine.py", line 95, in setupStation Mar 29 20:04:01 raspberrypi weewx[6167]: __import__(driver) Mar 29 20:04:01 raspberrypi weewx[6167]: File "/usr/share/weewx/user/swb.py", line 52, in Mar 29 20:04:01 raspberrypi weewx[6167]: weewx.accum.extract_dict['grid_energy'] = weewx.accum.Accum.sum_extract Mar 29 20:04:01 raspberrypi weewx[6167]: AttributeError: type object 'Accum' has no attribute 'sum_extract' Mar 29 20:04:01 raspberrypi weewx[6167]: Exiting.

[weewx-user] Re: Extract maximum value of an observation from loop packet
Thanks Tom and Matt for your prompt responses.
Apologies - I probably didn't quite make my intention clear.
I'm reading a sensor via OWFS, and am hoping to get weewx to only use the
maximum value measured during any 5-minute archive interval.
Going on from Tom's post, I want to make sure the value of
'$current.foo.max' is what goes into the database, rather than an average
or anything else.
I figure one way is to create/write a new data type in the owfs driver to
return the max value, or work on Matthew's suggestion above, but I'm hoping
there's an easy way to do it...
Thanks
Andrew

[weewx-user] Extract maximum value of an observation from loop packet
Hi I'm hoping to extract and log the maximum value of a sensor from any given loop (instead of the average by default). Is there a way to do this? (I've had a look at accum.py but my Python obviously isn't up to scratch to figure it out). I'm comfortable with needing to add to extensions.py but looking for the appropriate accumulator to use.
