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

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.

Matt,

 

Are you using Python2 or 3.

 

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

"""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

Hi Gary,

 

Yes to both questions.

 

Thanks for your help

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?

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

Finally, it's working. 

 

Thanks all for your help.

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.

 

 

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
