Weekly page not showing wind gust max data in table

[Phil Green]

Hello,

I have just spotted and issue with the reporting of the max wind gust on the weekly setting in the table at the left of my webpage.

I have altered the skin to show when the gust occurred.

The table is correct for month & year.

The graphical data is correct on the right hand side.

Can I check the data manually in the data base?

See attached screen shots.

Regards

Phil

NB: The weekly statistics start Sunday. It is not the same as "last 7 days."

The week started early Sunday morning at 0000, 30 August. From your graph, the wind speed was zero all Sunday morning. So, max gust this week would be zero.

Or, am I misunderstanding your problem?

Hello Tom,

Thanks for the clarification, I thought the Weekly stats were a rolling 7 days not from Sunday. 

Thanks for great software & support.

→ see $span($day_delta=7) for rolling 7 days (vs $week for since start of week)

[Phil Green]

Thanks for the info.

Where would I change the 

$week to $span($day_delta=7)

In the actual report file, in my case hilo.inc or in some definition elsewhere to set the aggravation period?

I have tried it in hilo.inc 

changing:-

#set $archive_data = [('day', $day), ('week', $week), ('month', $month), ('year', $year), ('rainyear', $rainyear)]

to:

#set $archive_data = [('day', $day), ('week', $span($day_delta=7)), ('month', $month), ('year', $year), ('rainyear', $rainyear)]

but it causes syntax errors.

So where would I change the definition of $week to a rolling 7 day period?

Regards

Phil

You didn't post what the "syntax errors" are, so it's hard to evaluate what went wrong. I suspect the problem is a technical one: precisely seven days earlier from the time may or may not lie on the start of a day. If it does not lie on the start of a day, then the daily summaries cannot be used to calculate 'wind' statistics. But, without seeing the "syntax error", I'm just guessing.

Why not just use the search list extension example that comes with WeeWX? It creates a tag $seven_day, which does what you want.

See the section Extending the list in the Customization Guide.

Hello Tom,

I will try $seven_day rather than $week.

When I tried $span($day_delta=7) instead of $week I got the errors.

I have looked back in my log at the error messages and they are shown below, I have since gone back to using $week

In hilo.ic

The section showing when the max wind occurred, I copied the variable from the tooltip for that section as tooltips don't work on my iPad in Safari?

      <tr>

        <td class="label">Wind Max</td>

        #for $archive in $archive_data

        <td class="data new_row hilo_$archive[0]">

          <span title="$archive[1].wind.maxtime">

            $archive[1].wind.max.format(add_label=False) ($archive[1].wind.maxtime)</span><br/>

          $archive[1].wind.gustdir.format(add_label=False)

        </td>

        #end for

        <td class="units">

          $unit.label.wind<br/>

          $unit.label.windDir

        </td>

      </tr>

Will let you know how I get on using $seven_day

[Tom Keffer]

Yes, that would be the error I outlined earlier. Type 'wind' appears only in the daily summaries. Seven days prior to a moment does not necessarily start at the beginning of a day, so the daily summaries are not always available.

But, it makes me think: perhaps tag $span should have an argument that forces the start time to be the beginning of the day...? Something like

$span($day_delta=7, $bod=True)

If 'bod' (aka, 'beginning of day') is True, then the start time is rounded to the start of the day.

Or, am I being too clever?

it sounds like a useful generalisation if it covers cases such as official rain start time each day being 9am - rather than $bod, make it $hour or $offset or similar e.g. $span($day_delta=1, $hour=9) for previous day’s rain and $span($day_delta=0, $hour=9) for today’s rain.

i guess it would imply a $span($week_delta=1, $day=2) and perhaps even $span($week_delta=2, $day=3, $hour=9)

[Phil Green]

Hello Tom,

I have implemented the tag $seven_day.

The report is working fine for the past seven days now, although one thing I spotted for the pressure low for the past seven days occurred at 0345 last Friday morning, not at 0345 today Friday, but it is clear on the plotted data on the graph what's happening.

So will leave it be for now.

First time I have implemented a change to my Weewx system in a while.

This is my station page hosted on a Raspberry Pi3 at home.

https://g0elm.dynalias.com/weewx/index.html

I am a professional electronic engineer/firmware developer  using 'C' so need all the help I can get with Python, it has another level of complexity, plus I never got on with C++!

Thanks again for your help.

Regards

Phil

[Phil Green]

Just realised that the report may not have updated as the graphs for Weekly were updated at 1500 and I have made the changes since.
