RTGD Zambretti Forecast Blank

[MikeQ]

I installed a SteelSeries page this weekend and installed RTGD to create and upload gauge-data.txt.  All that is working fine.  I also have the Forecast extension installed and that is working fine.  At this point, the only forecast I am trying to use on the SteelSeries page is Zambretti.  I have that configured in RTGD but when I look in gauge-data.txt it is blank so I must be missing something.

Here is the log info:

At weewx service start:

Jun 10 09:41:11 weatherpi weewx[973]: forecast: MainThread: Zambretti: forecast version 3.3.2
Jun 10 09:41:11 weatherpi weewx[973]: forecast: MainThread: Zambretti: interval=600 max_age=604800 winddir_period=1800 pressure_period=10800 hemisphere=NORTH lower_pressure=950.0 upper_pressure=1050.0

Jun 10 09:41:11 weatherpi weewx[973]: rtgd: RealTimeGaugeData scroller text will use Zambretti forecast data
Jun 10 09:41:11 weatherpi weewx[973]: rtgdthread: '/home/weewx/public_html/gauge-data.txt' wil be generated. min_interval is None

At regular report interval:

Jun 10 09:45:26 weatherpi weewx[973]: forecast: ZambrettiThread: Zambretti: generated 1 forecast record
Jun 10 09:45:28 weatherpi weewx[973]: forecast: ZambrettiThread: Zambretti: saved 1 forecast records
Jun 10 09:45:28 weatherpi weewx[973]: forecast: ZambrettiThread: Zambretti: deleted forecasts prior to 1559580328

From the forecast sample html page:

Zambretti

The forecast is Fairly fine, showers likely
Issued at 10-Jun-2019 09:45

And this is what I have in gauge-data.txt.  The ss page is reading this properly because the forecast is blank and not forecast missing:

"forecast":"",

I searched the group messages and I don't see anyone else having this same problem in the past. Thanks.

Hi,

Could you edit weewx.conf, set debug=2 and then restart WeeWX. There will be a lot of log entries but can you post a log extract from when WeeWX was restarted through until a couple of gauge-data.txt files have been generated.

I copied over forecast.sdb and here are the last few rows from SQLite Browser

[MikeQ]

I put a Dark Sky API Key into the RTGD config section and changed the scroller source to DS.  That works fine, so it looks like this is just a Zambretti forecast problem.  Using Dark Sky solves my problem since I just needed some kind of forecast in that box at the top of my SteelSeries page instead of an empty box.

[gjr80]

Thanks for the info. I could see nothing in the log extract that indicated an obvious error, what is missing though are any rtgd entries indicating that a (Zambretti) forecast data packet was received by rtgd. This leads me to think that the rtgd Zambretti thread is silently dying. The challenge now is to work out why. I guess you have solved the immediate problem by using the Darksky forecast, I'll try to get a VM running here over the next day or two and see if I can replicate the problem.

[Andrew Milner]

I dont know if this is relevant - but isnt the zambretti forecast only done once per day at 0900 I think - so there is likely to be no forecast initially available.

[gjr80]

I don’t know, I don’t think so. rtgd just pulls the last Zambretti forecast from the forecast database, so if there is no Zambretti forecast in the forecast database it would return nothing (None). This could have been the case with the first log extract but definitely not the case with the debug=2 log extract.
