Re: [weewx-user] Re: weewx crashes with error: unpack requires a string of len 104

[vk3anz]

First off, my apologies to all - given the subject line I completely missed 
that this question was related to my HP1000 driver.
Given the line number, you are using the latest version of the driver (I 
note that the driver that Bob provides above is based on the earlier 
version).
Is it possible to edit the HP1000.py file and change  line 524 from

interp_data = struct.unpack("8s8s16s8shbb14fbbh", rxData)

to

try:
interp_data = struct.unpack("8s8s16s8shbb14fbbh", rxData)
except:
loginf('Bad data: length = {0}', len(rxData))
loginf('Bad data: "{0}"', rxData)
continue

(Note the indenting of 4 spaces - Pythin is very sensitive to the indenting 
of the code.)
That should dump out to the system log file the bad data so that we can 
look at it and see what is wrong.

When I wrote the driver I only had my own weather station as a guide so if 
other firmware creates different sized (or formatted) records then there 
will be problems. It is hard to know the level of 'error protection' that 
is needed when yo don't know the sources of the possible errors (at least 
that is my excuse!).

I have an Actiontec C1900A and apparently I don't have the ssh enable 
option, only telnet.
I updated the firmware and gained two additional telnet options. I 
appreciate all your input.

[weewx-user] Re: Current wind graphic?

[RobbH]

Very nice! That's not exactly what I'm attempting right now, but I'll keep 
in mind for the future.

I hope you'll add it to the weewx wiki, so it'll be easy to find in the 
future.

I didn't find the realtime gauge data extension in the wiki, either, but 
found it here:

 It is possible to do darn near anything if you write an extension to do 
 so.assuming the account weewx runs as has privileges to do so.

[weewx-user] Re: rainstorm total rainfall SQL and demonstration python script

['Rich Altmaier' via weewx-user]

Hi Manuel, you and I have the same question!   How to create a weewx new 
tag!   I plan to study that over the next month or so.
Regarding the error below, in storm.py the intention is that you open your 
weewx database in line 42:  sqlite3.connect("your database filename")
For experimentation, assuming you are using weewx on Linux, copy your 
database file, which is probably at /var/lib/weewx, named weewx.sdb, to 
/tmp.  Then put the /tmp/weewx.sdb filename into the .connect line!  
Then you can try out my script.

Rich

Unfortunately, there is no support for a tag like that in weeWX. You would

[weewx-user] Customising reports: daily max and min temps over a month

[Richard Cain]

I was looking in the customising reports section of the wiki for how to 
draw a graph with just the highs and lows (temps) over a month. Now, of 
course, I can't find the specific section as the docs are so extensive!! 
Anyway, it wouldn't work for me so I had to do some tinkering. I think the 
main issue was to add the aggregate interval and also the marker_type = 
cross in order to see the values. Here is the relevant portion of my 
skin.conf:

 [[[monthhilow]]]
marker_type ='cross'
aggregate_interval = 86400
image_width  = 650
image_height = 360

hi
data_type = outTemp
aggregate_type = max
label = High
low
data_type = outTemp
aggregate_type = min
label = Low Temperature  

Hopefully it will be of help to some fellow newbies.
PS extensive docs+active forum = top quality product!!

Thanks
Richard

[Richard Cain]

As it happens I just had another lockup but weewx did pull the data since 
the lockup. I'm not sure whether this was luck or whatever. I did however 
have to restart weewx to get it going.

Once I realised no data was going to weewx, I activated the log before 
powercycling and restarting and have attached the file. Perhaps I am not 
suffering from lock up it could be something else. As a newbie, I have to 
admit a lot of the info means nothing to me.

NB I did try to use the device utility as instructed but I got the message: 
wee_device: error: --history option requires an argument

Regards

Richard

 Hi Graham,
Yes I did get a fix for the problem.  Thats the short answer.  The long 
answer is I hacked the driver and if I remember Weewx it self.  I'll post 
what I did, but I want you to know that I'm a (almost) 80 yr old truck 
driver not a programmer.
Maybe Susan will see this and chime in.  

Luck
Bob

[weewx-user] Re: weewx crashes with error: unpack requires a string of len 104

[Graham Seward]

Hi
Did you ever get a solution to this issue. I have weewx running with 
Susan's HP1000 driver connecting to a Maplin N23-dq (HP1000 clone). Took me 
a while to get it going in first place but eventually a firmware upgrade on 
the HP1000 resulted in success. However after a couple of hours of running 
weewx stops. Syslog throws up the same error as yours:

Weewex v3.8 on Raspberry Pi model B 
Short of shutting down and restarting I have not been able to resolve the 
issue

I've searched all the threads and can't find a solution - is there one?
Any help appreciated

[weewx-user] Re: Calculate the sum of a weekly energy production for a solar panel

[Marco Biner]

Hi Tom
I am again disturbing you.
As I said I managed it to summarize my energy production with your hint, 
but it is still not satisfiying my wish.
Here my code to summarize the production of a month:
#set $month_total=0
#for $day in $month.days
$day.dateTime.format("%A 
%d.%m.%y")$day.electric_ed.last
#if $day.electric_ed.last.raw is not None
#set $month_total  += $day.electric_ed.last.raw
#end if
#end for
#set $month_total = $month_total / 1000
#set $month_total = "%.2f" % $month_total
Total des Monats $month_total 
KWh

starting the sum with:
#for $day in $month.days
starts the first day of a month, what I need is to set the starting time 
one month back from today.
I tried to set the starting day with $month($months_ago=1)
 #for $day in $month($months_ago=1).days
gives an error:
TypeError: month() got an unexpected keyword argument 'months_ago'

As the graphic shows the values of the last week, rsp. the last month I 
would like to present in the table also the values of the last week, resp. 
the last month, not the values starting from monday or the the 1. of a 
month. So how do I set the correct start day for the summarisation?

Regards
Marco
