Well, it's nearly a month now,  and I still cannot reply in the positive.

I have posted the command sequence to the development mailing list, but, 
when I tried to implement it in the weewx driver on a buffer 70 to 80% 
full, the console has ignored me.

Other bits I have since found:

   - the console will not clear the buffer (even for the Windows s/w) when 
   it is very low (I do not know the lower limit)
   - The windows s/w has cleared the buffer from completely full (0x7fe0) , 
   as well as the high byte being 0x33 and 0x6e

Now that I have used Windows s/w to clear the buffer, I am going to have to 
repeatedly test that until I know how small a buffer will clear.
Then I will have to wait for it to build up again to try with the weewx 
code.

Re: [weewx-user] Re: No data from station

[Ruben Navarro Huedo]

Hello wmr300 friends.
I want add a second wireless transmiter to my wmr300.
I will use :
One transmitter (Oregon *STC300)* using channel 1 for: Temp, Humid and Rain
Another transmitter (Also STC300) using channel 2 for: Wind
I need to read all this sensors like one only weather station.
WMR-300 console is reading it correctly (after adding channel 2), but 
wee_wx doesn't "read" wind information.
Can i do this with weewx?
How?

In another vein: Have we some more information about clearing console 
datalogger from weewx?

Thank's a lot.

if the logger is full, then you will 'lose' data.  apparently the wmr300 
logger must be cleared by punching buttons on the console.  if someone 
knows of software that can clear the logger, please let us know so we can 
implement this in weewx.

if the logger is not full, then it should continue to capture data during 
the 30 minutes that weewx is not running.  when you start weewx, it should 
read data from the logger.

of course, if the logger's archive interval is set to 30 minutes, then you 
might be 'losing' data because you sampled just less than 30 minutes.

in any case, the weewx log will tell you how many records it retrieved from 
the logger.

Running now fine with last driver.
I has readed data from the datalogger from the wmr-300 installation.
This is OK, but if i disconnect it some time (for example 30 minutes) after 
starting weewx it begins to log real time data but looses these 30 minutes.
Is this Ok?

"nos"? did you mean "now" or "not"?

What is the logging interval set on the WRM300 console?  at 1 minute you 
get fewer than 30 days storage then it stops recording.
If it is full, it does not discard old log data but stops recording new 
results.

view the monthly or yearly summary and see what is recorded.

40 days?

which version of the wmr300 driver are you running?

if the logger is full it could take a few hours.  the driver will update 
the log periodically as it reads from the logger.
 
set debug=1 in weewx.conf then post the log from just before you start 
weewx until after the first archive record.

My stations has been running 40 days and data has nos been transfered to PC.
It is connected to a raspberry pi3

Weewx has detected ok wmr300 but it is reading records.
I can only read on log: "reading records since *NA**

Is this ok?
how many time could it take?

Thank's a lot.

Hi m,

This last version works fine. Previous version as well.
I've found out the error is caused by a usb cable.
It is a usb 2.0 cable which works fine with other devices. 
Quite strange.

Thank you for your support.

Re: [weewx-user] Re: No data from station

[Cameron D]

Hi MWall,
The legacy pyusb interface used in the current wmr300 driver only talks to 
libusb0, as far as I can tell.
Using the pyusb 1.0 interface I can specify which version of libusb to use 
or tell which one is called by default.  I have put that code in my 
"wmr300c" driver. I mainly use libusb1 and it seems reasonably robust.

The only problem I have found since November was when I used the windows 
software to clear the history and restarted weewx with very few, if any, 
records in the history. I seem to have an off-by-one or two issue.

The firmware of the wmr300 leaves a lot to be desired. There seems to be 
only one way to do anything and if you deviate from the path you are in 
trouble.

I previously promised to check the rain counter filling, but, having seen 
how little control is available from the PC in other aspects, I an sure 
there will be no way to remotely clear it.
The fact that I broke my wind vane shaft while having the system 
temporarily mounted on the ground encouraged me to get it out of my reach 
and fixed up on the roof.

agreed - i have seen this behavior with many different usb devices, not 
just the wmr300.  instead of returning an empty buffer, libusb0 raises an 
'error' that simply says 'no data available'.  btw, 'no data available' is 
a localized string in libusb, and the pyusb bindings do not provide a code 
to distinguish the type.

i am pretty sure that not every version of libusb behaves this way.  even 
more problematic is that there is no way to know the libusb version from 
python (at least for older versions of pyusb), even if someone figured out 
exactly which versions of libusb have this behavior and which do not.

as i understand it, the algorithm for wmr300:

- must not fail on 'no data available' "errors",
- must not fail on the first usb timeout,
- must fail on any usb timeouts after communication has been established,
- must fail on other usb errors

it must do this with every libusb version, or we need to figure out which 
libusb version(s) are immune to this and only support those.

when the firmware is wedged, there is not much we can do.

it would be nice if there were a way to re-establish the communication with 
the wmr300 *without* having to unplug/replug the usb.  usb reset does not 
do it.  hubs with power control could be an option, but then the weather 
station must have no batteries, must be bus-powered, and must retain logger 
data through a power cycle.

This is  actually an error in libusb0.  From my testing, the error message 
 about "could not detach..." is never cleared from the error  string buffer 
because the condition "no data available" is not regarded as an error 
condition at some level.
The first time you run weewx after plugging the USB device in, the kernel 
automatically attaches it (at least it does on my system) and the weewx 
driver has to detach it to access it in a different mode.
The next time (and subsequent times) weewx is run, the detach operation 
fails because it is no longer attached. This is OK, except for the spurious 
error message. 

You *should* still be getting data occasionally - if not then the wmr300 
console has gotten itself tied up in knots and you need to disconnect the 
USB and start again.

Try: 

   1. stop weewx
   2. unplug USB, wait 5 sec, reconnect USB.
   3. restart weewx.
   
this should fix both the error message and the no data condition.

Hi m,

Don't have access to the station at weekdays. Hope I can do it next weekend.
Also on another computer to discard a raspi problem.

"""Driver for Oregon Scientific WMR300 weather stations.

Sensor data transmission frequencies:
  wind: 2.5 to 3 seconds
TH: 10 to 12 seconds
  rain: 20 to 24 seconds

The station supports 1 wind, 1 rain, 1 UV, and up to 8 temperature/humidity
sensors.

Sniffing USB traffic shows all communication is interrupt.  The endpoint
descriptors for the device show this as well.  Response timing is 1.

The station ships with "Weather OS PRO" software for windows.  This was used
for the USB sniffing.

Internal observation names use the convention name_with_specifier.  These are
mapped to the wview or other schema as needed with a configuration setting.
For example, for the wview schema, wind_speed maps to windSpeed, temperature_0
maps to inTemp, and humidity_1 maps to outHumidity.

Maximum value for rain counter is 400 in (10160 mm) (4 = 0x9c 0x40).  The
counter does not wrap; it must be reset when it hits maximum value otherwise
rain data will not be recorded.


Message types -

packet types from station:
57 - station type/model; history count
41 - ACK
D2 - history; 128 bytes
D3 - temperature/humidity/dewpoint; 61 bytes
D4 - wind; 54 bytes
D5 - rain; 40 bytes
D6 - pressure; 46 bytes
DB - forecast; 32 bytes
DC - temperature/humidity ranges; 62 bytes

packet types from host:
A6 - heartbeat
41 - ACK
65 - ? each of these is ack-ed by the station
cd - ? start history request? last two bytes are one after most recent read
35 - ? finish history request? last two bytes are latest record count
72 - ?
73 - ?

notes:
WOP sends A6 message every 20 seconds
WOP requests history at startup, then again every 120 minutes
each A6 is followed by a 57 from the station
each data packet D* from the station is followed by an ack packet 41 from host
D2 (history) records are recorded every minute
D6 (pressure) packets seem to come every 15 minutes (900 seconds)
4,5 of 7x match 12,13 of 57


Message field decodings ---

Values are stored in 1 to 3 bytes in big endian order.  Negative numbers are
stored as Two's Complement (if the first byte starts with F it is a negative
number).

Hi m,

After that line, there is nothing else in the log related to weewx: No 
errors or any activity recorded.
At that moment, there was just 5 hours of data to read because, as I could 
not find any error message, I thought it was a station problem so I deleted 
the station's data log records.
A restart has not solved the problem.
Please, find attached full log since restart. It may help.

Thanks.

miguel,

the portion of the log that you posted looks fine - the last line shows 
that weewx is reading records from the logger.

if the 'running since' time can be trusted, then the driver only has to 
read about 5 hours of data.  even if the archive interval is 1 minute, that 
should not take too long, even on an old rpi.

what happens when you wait?

I believe that I had the same problem the first time I tested that driver.
I solved it simply restarting raspbian.

Re: [weewx-user] Re: No data from station

[mwall]

the 0.18rc3 driver *should* handle the 'no data available' and 'no error' 
conditions properly for english, italian, german, french, and spanish 
locales.

it does not yet handle timeouts properly.  ideally it would recognize and 
ignore timeouts on the initial communication, then recognize and fail on 
timeouts after communication has been established.

so if you experience timeout failures using the 0.18 driver, please post 
the exceptions!

hi alberto!

does weewx restart itself after any of these messages?

do these messages happen all the time, or just for short periods?

what is your hardware, operating system, libusb, and pyusb versions?

those are debug messages and in this case, they are not failures.  for some 
reason, some versions of libusb/pyusb report 'could not detach kernel 
driver' when there is simply no data on the usb.

to eliminate the messages, you could just set debug=0 in weewx conf then 
restart weewx.

or try wmr300 version 0.18rc3 - i made the driver less chatty:

Michael,
The code labelled wmr300c is my test driver to try to understand the
timeout issues.  It should work with the "A" model as well as the euro
model hardware wmr300.

You can copy it in alongside the normal wmr300 driver and switch between
them by manually editing the config file.  I have not given any thought
to whether the reconfigure program would work.

Cameron.

Re: [weewx-user] Re: No data from station

[Cameron D]

Hi Alberto,

OK - the comms errors would make sense to explain that.

If you are planning to erase and start again then a bottle of water
helps speed up the rainfall.
Or lift the raingauge top off and tip the rain buckets to and fro. That
way you can even count how much "rain" you have had.

Don't worry about packet capture - I intend to do that myself when I
have a bit of spare time.

Given Oregon's approach to control of the setup via PC (i.e. there is
none), I doubt there will be any software reset.  They do not even
correct the clock.

Re: [weewx-user] Re: No data from station

[Alberto Sánchez]

Hi Cameron,



I have had erroneous rain readings (9000mm or even more), I think due to
communication failures and in some cases I found cobwebs in the rain gauge.
Because of this I think I have reached the limit. At the moment I am in
tests, as soon as the weather station works correctly I will erase all the
data of wunderground and I will start again. The anticyclone we have in
Europe does not help me to speed up the tests xD



Many thanks to all for the help.



Mwall,



At the moment I do not have enough knowledge to help you capture packages
for the driver, but if you need me to do some test you can ask me.

Re: [weewx-user] Re: No data from station

[Cameron D]

Hi Alberto,
I have just checked my system after some rain and the database contents
look sensible.  I can see rain increments of 0.01 and 0.02 (inches) in
my 1-minute sample interval.

The web page shows total rain as 6.6mm since midnight, which agrees with
the console.

I am using Weewx 3.6.2, but with my test drivers. However I do not think
I changed anything in the drivers related to interpreting the data.

I noticed also on your weather underground page that you recorded 191mm
in 5 minutes on 12-Dec. That does not look right - you should see if the
weewx database shows the same set of values.

I thought the rain accumulator capacity was 40 metres of rain - that
should last 4 years even for the wettest place on earth. Unless you have
been supplying an extra source of water it should not need clearing just
yet.  It will be interesting if that does fix it.

Cameron.

this is typical behavior when the rain counter of the wmr300 has reached 
its maximum value.

once it reaches maximum value, it will no longer record any rain.

it will continue to record rain rate. (since the hardware emits rainRate, 
weewx does not calculate rainRate)

afaik, the only way to reset the rain counter is to punch the buttons on 
the console.

if you can find somewhere in the oregon scientific software that will reset 
the rain counter, please let us know!  even better, do a usb capture of the 
reset-from-software so we can do it in the wmr300 driver.

|Alberto

It is POSSIBLE that WU reports the time since the last reading change - but 
I still do not see what is happening because you do NOT have rapid fire 
enabled in the weewx.conf you posted.

Do you have multiple instances of weewx running by any chance - can you do 
ps -A and check that weewxd appears only ONCE in the list of processes

double check

Matthew needs to comment on how we have rainrate but not rain!!

mwall,

In the rain counter of the console appeared "HHH mm". I just reset and has

when was the last time you reset the rain counter? you can get this 
information from the wmr300 console.

Re: [weewx-user] Re: No data from station

[Andrew Milner]

Alberto - I do not fully understand your weather underground station.  If I 
watch your station for a while it looks as though there are two stations 
reporting - the last reported time keeps jumping between two sequences eg 
it can report last reported 10 secs ago, 15 secs ago, 8 minutes ago, 20 
secs ago, 8 minutes ago, 25 secs ago, 8 minutes ago, 30 secs ago, 9 minutes 
ago, 35 secs ago ... etc etc etc.

Is there anything in the log at/around the time of the rain?

What data is stored in the database between say 04:30:00 and 06:30:00 ??  
You can find this by
SELECT dateTime, rain, rainRate from archive where dateTime > 1482204600 
and dateTime < 1482211800;

Hi mwall,

It has rained tonight. The console has registered the rain and weewx has 
recorded the rain rate well but has not calculated the total rain. Example: 
Today's Rain 0.0 mm
High Rain Rate 1.3 mm / hr at 05:19:22 AM

Weewx 3.6.1
Driver 0,15RC3

I wanted to say that "I no longer lose data" with the new location of the
console.

alberto, roland, and others,

please try the latest wmr300 driver (0.15rc1).  it uses the usb 
initialization logic from 0.10, but it has the pressure/barometer and wind 
direction fixex that came later.

https://github.com/weewx/weewx/blob/master/bin/weewx/drivers/wmr300.py

it turns out that the wmr300 stations do not default to spewing data to the 
usb - the driver must invoke an interruptWrite periodically to keep the 
data flowing.

['Roland Ehle' via weewx-user]

Thank you Matthew. After some more digging and testing I came to the 
conclusion: It is not weewx itself that causes the issue, but the WMR300 
driver for some reason. I downgraded to weewx 3.5.0 and everything worked 
fine. After copying the WMR300 driver files I upgraded again to the latest 
version and the issue was present again until I copied the driver version 
0.10 to the location /usr/share/weewx/weewx/drivers.

So, after all, I have a working configuration :-) Thanks for your support

Regards,
Roland

At this point it's unclear to me if it's software or hardware, so I'd 
suggest a clean Raspbian with weewx 3.5.0 on it to try to recreate the same

Downgrade to python-usb 0.4.3 did not change the behavior. Clean install of 
Ubuntu 14.04.5 followed by a clean install of weewx 3.6.1 did not change 
the behavior. No I took a brand new Raspberry, put weewx on it, but I have 
exactly the same issue. In the past I was running my station on a Raspberry 
with weewx 3.5.0 successfully.

Station was reset using the reset button

roland,

before you try a different version of ubuntu, please try downgrading 
python-usb (to 0.4.3)
