there is also this one:

and you could always move root and everything to a usb hard drive to the

[weewx-user] Save reports to a temporary file system

[Janez Kranjski]

After SD card failure, my idea is to change the system to have less writes 
to SD card. 
Is this (https://github.com/weewx/weewx/wiki/Minimize-writes-on-SD-cards) 
still the simplest solution?

AFAIK, I will have to change path */home/weewx* to */etc/weewx* and use 
*systemctl 
restart weewx* for restart Weewx.
Something else?

[weewx-user] rtl_433 and acurite 5 n 1

[doug110144]

Hi,

I have a 5 n 1 and would like to access it by internet. I have an sdr 
receiver and raspberry pi. I have read I need  rtl_433 fto tune in the 5n1 
signal. I know little programming and looking for a compiled versionn of 
the 433. Some instruction on compiling the source code in cmake would also 
be useful.

Cheers, Doug

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

[vk3anz]

Mmmm - I'll have a look to see if there is an issue with the delay setting.

I've had a look at the log file and I can't see any reason why it should 
just stop like that. I fact, how do you know that it *has* stopped? Can you 
do a 'ps' or 'top' to se if the process is still running, or if you are 
using systemd, then do a status on weewx to see what has happened.

As far as I know (and in like with the original title of this thread) if 
there was an error then it should have displayed that and then continued. 
In my (limited) experience, Python code only stops when the program exits 
normally.

[weewx-user] Re: Pond.py multi senor watt and temp

[Andrew Milner]

1.  replace -max line length with -10 or whatever your max line length 
actually is ie set the amount to go back from the end of the file
2. replace f.readline()[-1] with f.readlines()[-1]

3. google for 'python read last line of text file' and there are several 
possible solutions similar to this one!!

[vigilancewx]

Thanks for your input Andrew

your additional comments have removed the indentation errors but for some 
reason weewx.sbd has stopped being populated by pond.py and the modified 
lines

but again thanks

Thank you. Solved :-)
Somehow I failed when I move/rename/copy archive file and "skin.conf" was 
an old one (which was changed by someone :-)).
Great support and super software.

1. make sure the skin is trying to create the .png file

I'm stuck at a bigger problem.

[weewx-user] Re: Pond.py multi senor watt and temp

[Andrew Milner]

indentation is significant in python

try:

try:
with open(self.filename) as f:
#  value = f.read()
#  line = f.readline()

f.seek(-max_line_length, os.SEEK_END)
line = f.readline()[-1]

value = line.split(',')
syslog.syslog(syslog.LOG_DEBUG, "pond: found value of %s" %

[weewx-user] Re: How can I find out why "Outside Humidity" isn't on graph?

[Andrew Milner]

the graph does not seem to have been generated since 27th March so I would 
check that it is still included in your skin and also check the log to see 
if any errors are being thrown

[weewx-user] Re: Lets see if I can get a response to this post. Installing new skins

[Greg from Oz]

Yes it is a great skin.
What are you running it on? What operating system?
I use that skin abut I have changed it 
slightly. https://weather.ubeaut.work/

I use mysql and not sqlite running on Ubuntu

You also have to add an extra column in the database.
Below is a script I did August 2017 so I could remember how to do it again:
#!/bin/bash
apt install python-dateutil python-ephem
echo this is to get Responsive skin to work.
wget https://github.com/dcapslock/weewx-responsive-skin/archive/master.zip
echo if you use responsive skin you have to add another column otherwise 
you get lots of errors
echo use mysql weewx database
echo alter table archive add column appTemp REAL;
echo copy aussearch.py to /usr/share/weewx/user
echo mkdir /var/lib/weewx/aussearch
echo uncomment  search_list_extensions = user.aussearch.ausutils in 
skin.conf

Don't know if that will help or not.

[weewx-user] How can I find out why "Outside Humidity" isn't on graph?

[Janez Kranjski]

I checked and I can see data for Outside Humidity in the database.




But as you can see on http://izo.amebis.si, there is something wrong on 
the graph. 

How can I find out what is wrong?

Hi Glenn


Yep did all of that. No sign of a swap file. I edited weewx.conf and all is 
fine

Re: [weewx-user] Re: Error reading lock file /etc/weewx/.weewx.conf.swp: Not enough data read

[Andrew Milner]

if you are working on a local network there should be no noticeable lag at 
all when editing a file - perhaps you should investigate the cause of the 
lag.

do ensure all your rpi sw is up to date though

i use putty to ssh into all my pis and pizeros - and have never had an 
issue with lag even when weewx is running together with web server and 
MySQL or a gui is running to display on a touchscreen - never any issues at 
all, although on two of the rpi's I do use a hard disk rather than the sd.
