XTides Setup and Weewx

[Simon]

Hello.

Just curious as to the setup needed for xtides to work with Weewx.

I've installed Xtides on my debian system using 

apt-get install xtide.

xtide and xtide data were installed.  I have added

[Forecast]

[[XTide]]

        location = Bangor, Northern Ireland

is there anything else needed to get this working?  very little shown on both weewx and xtides site.

hello simon,

first make sure xtide is doing the right thing by testing the 'tide' command (part of the xtide package):

tide -l "Bangor, Northern Ireland"

if you installed only xtide-data you will get this:

XTide Error:  STATION_NOT_FOUND
The specified station was not found in any harmonics file.
Error details:
Could not find: Bangor, Northern Ireland

for uk data you need to install xtide-data-nonfree as well.

once you get a proper output from tide, then you can work on the weewx side of things.

be sure to specify the location properly:

[Forecast]
    [[XTide]]
        location = "Bangor, Northern Ireland"

any parameter that contains a comma will be interpreted as an array, and since you want "Bangor, Northern Ireland" not ["Bangor","Northern Ireland"], you need to enclose your location in quotes.

here is an example of how to use the tide data in your templates:

#if $varExists($forecast)
for $tide in $forecast.xtides
  $tide.event_ts $tide.hilo $tide.offset
#end for
#end if

the attributes for each tide prediction are (this should display all the attributes of the next tide):

$forecast.xtide(0).dateTime     ## date/time that the forecast was requested
$forecast.xtide(0).issued_ts    ## date/time that the forecast was created
$forecast.xtide(0).event_ts     ## date/time of the event
$forecast.xtide(0).hilo         ## H or L
$forecast.xtide(0).offset       ## depth above/below mean low tide
$forecast.xtide(0).location     ## where the tide is forecast

m

[Simon]

Matthew your a life saver!  Thanks, got the xtide-data-nonfree installed and is now working for the location.

Thanks Again!

simon,

the forecast.inc file will display a wu or nws forecast in tabular form, along with tides, if you have them.  if you are not collecting wu or nws forecasts, then you won't see anything - the tides are embedded within the other forecast data.

if you just want to see tides, then put the snippets i posted earlier in this thread into one of your .tmpl files.

if you want weather and tides, enable wu forecasting then include the forecast.inc file as per the instructions on the wiki.

[Simon]

Thanks Matthew, I am using forecast.inc to display all data from WU

yet the tides data is not even show let alone populating

if you take a look here:

http://darkmoon.org.uk/weather/

you'll see no tide data shown. yet xtides installed and working in command prompt and its own web gui along with UK data.

I just dont know why it is not putting the data and tides column into the forecast.

if you need me to attach my files let me know though forecasting is working, but not tide data,

there you have it:)  sorry for my bad, i just didnt see ANY mention of this in the wiki:)

Ok Matthew

I think the problem maybe that xtides forecast is trying to grab the data straigtht away from the command

tide -l "Bangor, Northern Ireland"

problem being the initial output is not tide data.

for example:

the data marked red is put into the syslog file and my guess is the forecast just terminates due to this initial output. is there anything that could be done about this?

simon,

the forecasting module simply parses the output from the xtide command.  it ignores the disclaimer.  however, it was looking for an exact match with the location, and the bit about 'READ flaterco.com/pol.html' gave it indigestion.

this has been fixed in forecast.py at r1855

https://sourceforge.net/p/weewx/code/HEAD/tree/trunk/bin/user/forecast.py
 

[Simon]

I think your right with the info. new forecast.py loaded (after removing forecast.pyc)  weewx loaded again, however the syslog shows a bit more info, but, xtides terminating again.

simon,

silly computers always do what you tell them to do, not what you want them to do :)

in the snippet you posted, the request is for tide events between '2014-01-07 00:00' and '2014-01-07 01:00'

there is nothing happening during that time period.  did you override the 'interval' for XTide in your weewx.conf?

you can verify with these:

tide -fc -df"%Y.%m.%d" -tf"%H:%M" -l'Bangor, Northern Ireland' -b'2014-01-07 00:00' -e'2014-01-07 01:00'

tide -fc -df"%Y.%m.%d" -tf"%H:%M" -l'Bangor, Northern Ireland' -b'2014-01-07 00:00' -e'2014-01-08 01:00'

i will fix forecast.py so it does not report 'generate tide failed' when there are simply no results.

as you see the second one done what it was suppose to, but my forecast for the next 5 days shows nothing some maybe i am missing something here.  I was expecting xtides to populate the 5 day forecast on my site with tide data as well.

my weewx.conf forecast is like so:

    save_failed = True

    

    

    [[Zambretti]]

        # hemisphere can be NORTH or SOUTH

        hemisphere = NORTH

        

        # The interval determines how often the trend is calculated

        interval = 600

        

        # The lower and upper pressure define the range to which the forecaster

        # should be calibrated, in units of millibar (hPa).  The 'barometer'

        # pressure (not station pressure) is used to calculate the forecast.

        upper_pressure = 1050.0

what does your log report as the xtide interval?  there should be a log entry something like this soon after weewx starts up:

Jan  7 10:36:41 saga weewx[30389]: forecast: MainThread: XTide: interval=1209600 max_age=None location='Boston'

[Simon]

hmmm

Jan  7 14:59:47 localhost weewx[10810]: forecast: MainThread: XTide: interval=1800 max_age=86400 location='Bangor, Northern Ireland'

must be from the start of [Forecast] 

 # How often to calculate/download the forecast, in seconds

    interval = 1800

i'll add the following into [[XTide]]

# How often to generate the tide forecast, in seconds

interval = 1209600

yes indeed.  the forecast configuration is analogous to the ImageGenerator configuration - when you specify something at a higher level it is applied to each lower level section.

fwiw, this is the minimal configuration to do all four forecasts:

[Forecast]
    database = forecast_sqlite
    [[NWS]]
        lid = MAZ014
        foid = BOX
    [[WU]]
        location = 02141
        api_key = xxxxxxxxxxxxxxxx
    [[XTide]]
        location = Boston

there is no need to specify an option unless you have a reason to override it.

simon,

typically each forecast runs at a different interval.  for example, the zambretti forecast should be run about every hour, possibly every half hour for some locations.  the weather underground forecast is only good for 1 hour intervals, and the forecast itself is only updated every 4 to 6 hours, so no reason to download more often that that.  the tide forecasts never change, so the default is to generate those about once per week.

congratulations!  you found another bug!  the xtide forecast module was detecting the fact that your tides are reported in meters, but it was failing to do the conversion.  my fault for not testing on more test data.

fixed at r1857

Hi

I am also trying to get xtide to run in weewx only the tides no weather forecast from WU or similar                                              

The tides for Liverpool can be generated from xtides command line

So following on from the snippets in this thread

[Forecast]
    [[XTide]]
        location = "Liverpool"

I have added the above to weewx.conf                                        

 

As Matthew said

“if you just want to see tides, then put the snippets i posted earlier in this thread into one of your .tmpl files.”

 

To my index.html.tmpl added

#if $varExists($forecast)

for $tide in $forecast.xtides

  $tide.event_ts $tide.hilo $tide.offset

#end for

#end if

 

 

$forecast.xtide(0).dateTime     ## date/time that the forecast was requested

$forecast.xtide(0).issued_ts    ## date/time that the forecast was created

$forecast.xtide(0).event_ts     ## date/time of the event

$forecast.xtide(0).hilo         ## H or L

$forecast.xtide(0).offset       ## depth above/below mean low tide

$forecast.xtide(0).location     ## where the tide is forecast

Checking the Wiki If you wish to use WU and using the forecast.py for displaying the tide data things start to get a wee bit complicated

To display only tide data on the index page what additional  mods do I need to make

 

Thanks for your help

Hello.

Just curious as to the setup needed for xtides to work with Weewx.

I've installed Xtides on my debian system using 

apt-get install xtide.

xtide and xtide data were installed.  I have added

[Forecast]

[[XTide]]

        location = Bangor, Northern Ireland

is there anything else needed to get this working?  very little shown on both weewx and xtides site.

the # made a big difference in the syslog

but it now produces other errors

any ideas

Hi,

I am sure Matthew will hit both errors in one go just by looking at the logs :) but the rest of us might need a bit more like index.html.tmpl (or the relevant portion of), weewx.conf less any user names/passwords and a log snippet from when weewx starts up until the error(s) occur.

Gary

I think the tide error you are seeing is due to not having XTideForecast in your service list at the bottom of weewx.conf. You will need to add

, user.forecast.XTideForecas

to the end of the service_list setting in weewx.conf. If you look through the preamble of forecast.py (which is located in the user folder wherever your weewx binaries may be located on your system) you will find details on what settings/changes need to be made to get the various elements of the forecasting services to work.

Hope this helps.

you need to tell the cheetahgenerator about forecast variables.  put this in your weewx.conf then restart weewx:

[StdReport]
    ...
    [[StandardReport]]
        ...
        [[[CheetahGenerator]]]
            search_list_extensions = user.forecast.ForecastVariables

this is another network failure, but this time when trying to contact weewx.com.

this is a bug in restful.py.  it should be %s not %e.  fixed at r1861.

if the bug were not there, weewx would continue trying to upload instead of terminating the restful thread.

it looks like you have network problems.  try some pings and dns lookups from your pi to figure out where the problem is.

one more thing.  try this:

[StdReport]
    ...
    [[StandardReport]]
        ...
        [[[FileGenerator]]]
            search_list_extensions = user.forecast.ForecastVariables

instead of this:

[StdReport]
    ...
    [[StandardReport]]
        ...
        [[[CheetahGenerator]]]
            search_list_extensions = user.forecast.ForecastVariables

that could be the source of your "cannot find 'forecast'" problem.  it is caused by a bug that was fixed in 2.5.1.

the dns/network problems are independent of any weewx version.

I have tides!  Thank you.  just need to sort out formatting, but that should not be a problem.

hey simon,

the formatting is kind of a pain.  the forecast table was designed without any external constraints.  when you embed it in a div such as the 'content' div in the Standard skin index.html page, the forecast table widths are ignored.

the reason is beyond my css mojo...

one approach to fixing it is to punt the disclosure triangles and make the dates clickable instead like Marten Oosterhoff has done here:

any ideas what I could be missing?

[mwall]

hi mark,

there have been some fixes applied to forecast.py so that it will handle the additional output emitted when you use the xtide non-free data.

replace your bin/user/forecast.py with this one from the repository:

https://sourceforge.net/p/weewx/code/HEAD/tree/trunk/bin/user/forecast.py

it should work in the 2.6 alpha release as well as the 2.5.x releases.

m

[mwall]

sorry, it looks like you already did that.

the other problem is that you need to put your location in quotes if it contains a comma, otherwise configobj treats it as an array.

location = "Bangor, Northern Ireland"

not

location = Bangor, Northern Ireland

m

[Mark Kerr]

Ahhh, D'oh I had even read about this and still somehow managed to miss quotes in the conf file. Fingers crossed that was all it needed

Jan 11 15:54:30 blackadder weewx[13004]: forecast: XTideThread: XTide: saved 109 forecast records

Jan 11 15:54:30 blackadder weewx[13004]: forecast: XTideThread: XTide: deleted forecasts prior to 1387036470

looks good to me :)

it should have told you by spitting out an error message about not finding "['Bangor','Northern Ireland']".  i'll have to write a unit test for that.

its all working now for mark. ;)
