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.
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'.
root@weather:~# tide -l "Bangor, Northern Ireland"
Bangor, Northern Ireland - READ flaterco.com/pol.html

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....
