Re: [weewx-user] Re: automatic reload of weewx.conf

Get a power pack with "pass through charging". Cheap  and easy battery
backup. If your card is ~yr old you are on borrowed time IMHO. SSD would
save a lot of headaches.

You're going to want to replace that SD card sooner rather than later, 
if you found some files corrupted after a power hit.

I went to SSD. They are so cheap now at the size we use. That SD card
will bite you and it is painful.

expensive but will last much longer.

Well, does it?
Pi's are power managed in that they draw what they need based on what 
they're doing.
Sure, the Pi 4 is capable of drawing more, but will it do so for the 
workload needs of WeeWx and related SW?


For one thing the Pi 4's new SoC is on paper 2-3x as efficient as a Pi 
3, so things may either run ~2x as fast or waste fewer cycles getting 
the job done.
Only way to know is to run exact same OS version and software stack on 
two different units side-by-side, and measure how many watts they're 
actually pulling nominally and during peak times and actually compare 
the two.   YMMV.  =D


I'm holding out for the 4 GB Pi 4, which is out of stock already, 
where I live.
Not needed for WeeWx, but as my main development platform, while a 
slower Pi Zero runs the code developed and unit tested on the Pi 4.


I sure do like having a faster box so compile times are faster.  =D
And to that end, eventually there will be a 64-bit Raspbian on the 
official support train, in which case the additional memory will get 
me past some hurdles where the 2 GB virtual memory per process 
currently has me shutting off SW features that gcc/ gplusplus can't 
manage to build with only 2 GB VM.

But I digress.  ;-)

Re: [weewx-user] Total newbie - WeeWx not uploading at all after being great on Raspberry Pi

[Robert Lorenzini]

Here is what I do. Someone please correct any errors.
stop weewx   sudo /etc/init.d/weewx stop
remove power to  Van2
restart and set time on Van2
check time on Pi is correct or reboot and wait until it is correct.
restart weewx   sudo /etc/init.d/weewx start
watch syslog for Pi d/l from Van2 sudo tail -f /var/log/syslog

sometimes the data has to be cleared from Van2  ( search doc)

I recommend using a power pack with "pass through charging"
for a cheap UPS and a SSD for the Pi. Those cards all die
at some point and a cheap drive will save a lot of time and
frustration. A hardware realtime clock would have saved you
all this trouble. After an interuption the Pi and Van2 will
not have the same time and will be unable to d/l.

any of it.


My friend emailed me this:

Try   sudo /etc/init.d/weewx start

I did try that using my VNC Viewer to connect to the Pi and Weewx said 
it started.  But it's not uploading.  So ...?  I don't even know where 
to begin.  Any and all ideas are very welcome.  Thanks!

[weewx-user] Clock

I would like to add a clock module to my Pi but that port is taken by

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

After my first failure I switched to a SSD.

Is this

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?

Re: [weewx-user] Re: Most reliable mini computer for weeWX?

You must have a good card, mine did not last near that long. I'm on SSD now.

I should probably back up the micro SD card, since it's been in use 
for a year.


This thing has not stopped working.  No outages.  Uptime runs from 
whenever I do an apt-get update to the next time (I always reboot 
after doing an upgrade because that's one of the times weewx crapped 
out, when I updated some system stuff).


I have no experience with other systems.

Re: [weewx-user] Experience installing WeeWX on a Raspberry Pi

[Robert Lorenzini]

I would like to warn you about running on an SD card. I ran Weatherview 
for 5 yrs + on
a Linksys NSLU2 with an old laptop hard drive that must have been 4 
years old at that
time. I got worried and switched to a Pi with a recommened SD card. That 
lasted 6 mo.
I'm now here on Weewx with the Pi and a SSHD. I renamed my old DB and 
all was

good to go. Thanks folks.
