Hi Guys,

I have been trying to upgrade to version 4 since my Pi decided to throw a strop.

Anyway, it's been fairly hardwork.

I have this message continuous in the logs:

DEBUG weewx.drivers.ultimeter: Decode failed for '----': invalid literal for int() with base 16: '----'

just coming every 1s or so.

I also have some other issue which I can't seem to find:

ERROR weewx.cheetahgenerator: Generate failed with exception '<class 'TypeError'>'

Apr 9 14:45:16 weewx weewx[868] ERROR weewx.cheetahgenerator: **** Ignoring template /home/weewx/skins/Standard/index.html.tmpl

Apr 9 14:45:16 weewx weewx[868] ERROR weewx.cheetahgenerator: **** TypeError: '>' not supported between instances of 'NoneType' and 'float'

My wind vein has blown off the roof, so wind direction and speed are probably both None.

Whether this is something to do with it I don't know, but I can't get the index template generated.

Thanks

Chris

Looks like you switched to Python 3 from Python 2.7 and the driver isn't compatible, based on the error message.

Oh, the ultimeter isn't supported on Python 3 and ver 4 weewx ?

Is that what your saying?

Oh, had not planned on that.

I found some sort of error in my template, which I've kind of resolved.

But the Ultimeter driver... not sure on this one.

Thanks

The driver should work fine with Python 3.

However, the driver has a small, non-functional bug that causes it to emit that error message when it encounters a "dash" value. It's non-functional because it emits the right value ("None"). It just shouldn't log an error.

Try this version. I've taken the occasion of having a real, live Ultimeter user to also fix some ambiguities around byte array types. Let me know if it works.

Don't worry, I think I may have patched it. I'm not really much of a coder (although can do some stuff)...

Modded your file. see line 345 onwards.

See attached

You had the right idea, but we have to be careful about values that are encoded in only two bytes.

Try this version.

Sorry it doesn't like that one:

it prefers mine, lol

Also why when ftp happens 1 of the files gives this:

Apr 10 08:45:37 weewx weewx[5576] ERROR weewx.reportengine: ftpgenerator: Upload failed

the file seems to be on the ftp server (I tried deleting everything on the ftp to see if it uploads it)

only happens for this 1 file.

I notice that all my files in /var/www that upload are set with root permissions, does that have anything to do with it?

Not sure how to make weewx change set these to www-data permissions

So I manually deleted all the files from the remote ftp server to make it upload a fresh.

it tries to ftp ALL files twice, but fails on the first NOAA txt file, the partial file from 2014-10 when station started up.

because this fails (although I can see it on the ftp server), it tries a 2nd time to upload everything, then quits on this file again.

the whole process takes 3 minutes to upload as it tries to upload everything (twice on every 5min cycle) because that 1 file fails.

any ideas on a fix for this?

Too many years using Python 2, not enough on Python 3. Try this version of ultimeter.py.

Thanks, driver seems good, (no complains at the logger anyway)
