New User Setup issues - Raspberry Pi, Fine Offset HP1000 - weather reports show values being appended/summed

[Matt]

Hi All,

First post.

I got Weewx set up on a brand new Raspberry Pi 3 model B yesterday.  I saw that it was posting data but last night most of the data was incorrect (e.g. outside temp 0 degrees C when it was actually 10 degrees).  I decided to leave it and went to bed.  Today I am seeing better values but all readings appear to be summing/appending to the previous reading.  For example, the temperature has risen from 0 to around 21 degrees very uniformly.  The actual temperature is around 13 degrees.

I have an Aercus station, identical to Fine Offset HP1000.  I have set Weewx driver to both 'simulator' and 'Fine Offset' with no change in data.

I read somewhere about an HP1000 driver written by aussie susan but editing the daemon file was beyond my capabilities so I couldn't proceed with it.

My station can be seen at: https://www.pwsweather.com/obs/ILITTLEW9.html#

I appreciate that I will need to provide logs etc, but I am work at the moment and will upload logs later.  I just wanted to get the post up to see if anyone had experienced anything similar or has any advice for a newbie.

I love the functionality of weewx and look forward to using it.

Many thanks in advance.

Matt

the chances are that your uniform incrementing values are the simulator data whic I hthink looks like a sine wave!!

chances are that you are set on simulator and are not reading any data from the station.  

Only the log will provide the answer.  the simulator does exactly what it says, it simulates A weather station (Not a specific type) and generates data to be put in the database which can then be used to generate reports.  It is not simulating your specific station!!

when you post the log post from before starting weewx until at keast one archive interval has passed - the length of the interval is whatever you have specified in weewx.conf

[Matt]

Thank you, that makes perfect sense.  I'm sure I followed instructions which said to select 'Simulator'.  I'll change to Fine Offset when I get home, after I've retrieved the logs.  I'll also try to find out more about how to install the driver for HP1000 but google wasn't too helpful last night!

Matt,

You need to use the HP1000 driver or Interceptor driver for this device not the Fine Offset one. If my memory serves me correctly the FO driver is for a USB device where as the HP1000 is a wireless device.

Thank you. I think I realise that now however I'm unable to install the HP1000 driver as the instructions on its GitHub page aren't working for me.

Still investigating...

Matt,

Yes the syntax is incorrect. I can’t give you a full answer for an hour or so as I am rather occupied at the moment. Have a look at other driver install instructions and follow the same logic. Check back later if you are still having trouble and I will walk you through the installation.

Hi,

I'm making progress.  I managed to install the driver using a number of different sources and lots of trial and error.  For anyone else seeing problems, what I did was:

wget -P /var/tmp weewx-hp1000.zip https://github.com/AussieSusan/HP1000/archive/master.zip

cd var/tmp

unzip master.zip

sudo ./wee_extension --install=/var/tmp/HP1000-master/hp1000.tar.gz

sudo ./wee_config --reconfigure

Chose the number next to HP1000 then restarted weewx.

Now, next issue is that there appear to be some settings I've got to set.

The log says:

/home/weewx $ tail -f /var/log/syslog

I'm trying to find out where I need to specify the ip_address_mask now.

Cheers,

[Matt]

The ip_address_mask which is the IP address of the weather station, goes in the HP1000 section of the weewx.conf file as follows:

ip_address_mask = "192.168.1.255"

Finally, it's working. 

Thanks all for your help.

Apologies for resurrecting an old thread but I'm trying to do a fresh install using the commands listed above, using Weewx 4.1.1 and the HP1000 driver is not appearing in the list so it cannot be chosen.  Has anything fundamental changes between the previous and current weewx versions?

Thanks

Hi,

Would help to know what commands you entered and what output you received. Can you please try again and copy/post the exact commands entered and the resulting output to the console.

OK, let’s start with the obvious. Is HP1000.py in /home/weewx/bin/user and if you view the contents of the file is it legible code?

Gary

Hi Gary,

Yes to both questions.

Thanks for your help

"""hp1000 driver for the weewx weather system

This driver communicates with the HP1000/WS1001/XC0422 and whatever other clone

weather stations respond over the LAN to the 'easyweather' protocol.

Communication starts with a UDP IP broadcast on the local subnet to port 6000 to

see if the weather station responds. The broadcast packet is structured as:

Offset  Value           Structure       Comment

0x00    PC2000          8 byte string   Identifies the calling station

0x08    SEARCH          8 byte string   Command

[steeple ian]

Matt,

Are you using Python2 or 3.

The driver was last updated 11months ok and may not be compatible with Python3

It's not been updated and should not be used with Python 3.

This is something I have on my 'to do' list but I must admit it is not the top priority.

On the other hand, the source is there if anyone else wants to have a go.

Ok, thank you for confirming.  I shall wait patiently.
