WMR300 driver update

[Cameron D]

I have attached an updated WMR300 driver, based on v19rc6 from v3.8.2

The history clear has been reinstated, and an issue with the console stopping data transmission has been fixed.

This is done simply by identifying when no data has been received for a minute and issuing an instruction to restart sending data.

To install:

Either:

  A. you could rename it and overwrite the wmr300.py file in weewx/drivers (having first made a backup)

or

  B. (safer)

  1. copy the file into the "user" folder of the installation folder.

  2. edit the weewx.conf file to point to the new driver: in the [WMR300] section, change

    "driver = weewx.drivers.wmr300"

    to "driver = user.wmr300-v19rc6+fix"

    

the driver has extra options that you can enable if necessary:

    debug_history = 1

    debug_timing = 1

    

This code has been working continuously under weewx 3.8.0 for 6 months with no hangs and many instances where it needed to restart the console.

I have a 1 minute history interval and clear at 6%, which means the history clear runs approx every 32 hours.

Thank you very much Cameron,

I will try to test it as soon as possible.

A lot of thank's Cameron.

I will test it in some minutes.

I have some log of 3.8.2 standard driver version when stops receiving data:

[Ruben Navarro Huedo]

Running your version.

I can see debug is enabled by default.

Is this ok?

I will tell you in some hours the result.

[Cameron D]

Hello Ruben,

On the new code, I have deliberately left in the listing of bogus history records, as I am interested in their occurrence. I was worried that there was something about my history clearing that was creating them, however your system still has them even before the history clear begins.

They are only printed during startup or clearing history and I have never seen more than 30, so they should not full the logs. However they do accumulate so they might need to be examined in more detail in the future.

On the log that you posted from 3.8.2, the messages are simply saying the console is not giving any data, but there is no indication as to why.

If you enable the debug_timing option in my code then it should reveal issues that could have caused the hang-ups.

Cameron.

[Ruben Navarro Huedo]

Oks.

Now is running with your code.

If i have more problems i will enable it and we will study the problem.

Thank's a lot.

[Leo De Geer]

HI

I'm now running the new driver on 3.8.1 and all are running ok for the first day new record

Good work Cameron

Regards Leo

Hi Cameron and all other users of WMR300. I switched today to the last version of WMR 300 driver and up to now looks ok

Paul

[Ruben Navarro Huedo]

Same here.... Now 12 hours uptime.

Record with 3.8.2.

With 3.8.2 original driver no more than 4 - 5 hours.

[Juan Antonio Mosquera]

It seems that with the new driver everything is OK. I will inform you. Thank you!

I have detected a problem that I do not know if it is the driver or the skin (Belchertown). There are spaces in time that I do not have wind data, it can be seen in the capture that I attach.

Thank you.

Hola,

Curiosamente desde que he publicado el mensaje tengo datos continuamente... 

Gracias, saludos.

[Juan Antonio Mosquera]

I have problems again, at a certain moment weewx stops receiving wind data. You can see it at www.meteomontaos.es

Greetings and thanks

OK, I can see you have recorded zero wind reading for today. What does the WMR300 console display?

Do you have wind chill and heat index configured for hardware or software?

If you have not changed the default from "prefer_hardware" then it suggests that the console is also seeing zero wind speed, because (if I translate the Spanish OK) then these values are tracking the temperature exactly.

Can you see the anemometer rotating?

Cameron.

[Ruben Navarro Huedo]

I have tested your driver some days.

All is very stable with 2.4.* Kernel but now with 2.9.*

With 2.9 systems hangs up randomly and after boot again i can't see anything on logs.

[Cameron D]

If you post the logs anyway, there might be something meaningful to me.

I am not aware of any kernel version sensitivity.

When you say "hangs up", is it just the same symptom of simply failing to collect any data, or does weewx stop or hang totally?

[Ruben Navarro Huedo]

It hang raspberry totally

[Cameron D]

Sounds bad.  I guess the most likely issue is that they have changed the USB kernel code in some way.

I doubt that there is much I can do by way of debugging, as it seems specifically tied to your kernel. Have you checked for other people reporting USB issues with this version?

All I can offer is you could try my experimental driver based on libusb1, since that is the library that interacts most directly with the kernel usb code.

It will stay experimental, as Matthew has reasons for not complicating the main driver.

I have an updated version from what I posted last year, which is keeping parallel with Matthew's changes.

Same here:

4.4.* is stable.

I have the same problem with other Raspberry running a WMR200 weather station.

The latest Raspbian kernel is 4.14.70-v7+ for the pi3plus, based on doing an upgrade a few minutes ago.

Are you compiling your own kernel and perhaps getting some settings wrong ?    I'd also expect (untested) that the Raspbian folks might have some patches in their kernels perhaps (?) 

[Ruben Navarro Huedo]

NO

I don't compile kernel.

I run raspbian distributed stable kernels and also i have tested with latests rpi-update kernels with same result.

[Ruben Navarro Huedo]

Cameron: Yes... i can test your experimental driver.

I don't know what has changed from 4.4 to the nexts kernels, but with 4.4 all is stable.

[Ruben Navarro Huedo]

Juan Antonio: Con el fin de intentar ver la causa del problema.

¿Sería posible ponerme en contacto contigo por privado?

The panel shows wind data, the anemometer moves, I have tried unplugging and plugging, everything works correctly. I have disabled Belchertown extension and it does not work either. Everything points to a bug in the driver.

Thank you.

the problem with the kernel happens to me with previous versions of weewx and the wmr300 driver.

[Ruben Navarro Huedo]

And the same with wmr200 driver

[Thomas Keffer]

I hesitate to wade into this, but are you running as a privileged user (i.e., 'root')? What happens if you run unprivileged (with appropriate /dev permissions, of course)?

There are multiple issues being posted here, neither of which are likely to be from the changes I made in the original thread post.

I will create two new threads - one for each of what seem to be the major issues, and see if we can concentrate the discussion.

Cameron.

[Ruben Navarro Huedo]

I haven't tested it with non-root .
How can I give privileges to /dev ?

It's in the Wiki.
