tides forecasting can't find London

[Cycle London]

Hi.
I have my weather station running nicely, and decided to go ahead and install the 'forecast' extension.  I also grabbed the 'nonfree' data as I'm located near London in the UK...

  root@weather:~# history | grep apt
  505  apt-get install xtide
  506  apt-get install xtide-data
  507  apt-get install xtide-data-nonfree

I have an API key from the UK Met Office, and am ready to rock.   First, I decide to test xtide...

root@weather:~# tide -l London

XTide Error:  STATION_NOT_FOUND
The specified station was not found in any harmonics file.

Error details:
Could not find: London

OK, so there's a problem.  No luck with 'London, UK' either.  Or 'London, England'.  I google and find a thread on this group from 2014, and one of the responses in there is to test with 'Bangor'.

Yep, that works.  So I look for 'weewx predict tides' in google and get this site: http://tides.mobilegeographics.com/

I search in there for London, and get several responses (see screenshot).  I tried the first three of them, but get an error with each.  I even tried 'harmonics.world    51.5000° N, 0.0833° W', and the coordinates.  Every time, I try with double quotes and single quotes.  Nothing seems to work.

This is going to be really easy, and I'll kick myself when someone points it out to me....

Thanks.

perhaps try a more recent harmonics file?  dwf no longer dos the world harmonics, but this one is more recent than the one you tried:

ftp://ftp.flaterco.com/xtide/harmonics-dwf-20111230-nonfree.tar.bz2

Hi.

I grabbed that file, unzipped it and put it into /usr/share/xtide.

XTide Fatal Error:  BAD_OR_AMBIGUOUS_COMMAND_LINE
The command line could not be rationalized.  Probably you have provided an
unrecognized switch or invalid argument.  However, you can also get this
error by using ambiguous syntax.  For example, the shorthand -lw5 could mean
"set the line width to 5" (-lw 5) or it could mean "load the location
named w5" (-l w5).

Still no luck.  Tried with 'UK', 'England' and with no country.

it looks to me as though xtide no longer supports locations outside usa since ukho took offence

http://www.flaterco.com/xtide/faq.html#60

maybe u need a different source for the data??

[Cycle London]

I was aware of that, but the wiki (https://github.com/weewx/weewx/wiki/forecasting) says..

"Tide data for Canada, Germany, and the UK are in a separate package:

sudo apt-get install xtide-data-nonfree"

I thought that by installing that, it would work.

Oh well.  i'll have to dtop the ride part.

Thanks for the help.  I'll try to get 'regular' predictions working.

As a citizen of the most corrupt, greediest and sickest country on the face of the planet, allow me to apologise for the behaviour of the greedy MFs over at the UKHO.
