Thanks but can you provide the corresponding log entries as well please, it should show a lot of hex characters, I need to marry up the raw data from the GW1000 with what is being observed and what comes through when decided as per the GW1000. The logs have the raw data.

lemuba commented 4 years ago

Puhh, where do I find those logs? Could it be in /var/log/syslog, which is currently empty on my system...?

http://weewx.com/docs/usersguide.htm#Nothing_in_the_log_file

gjr80 commented 4 years ago

That is a good question, it depends on your system. What operating system and version?

lemuba commented 4 years ago

Dietpi Debian System on a Virtual Machine (Synology Diskstation Virtual Machine Manager). I´m currently installing rsyslog and will check again...

Thanks, exactly what I was after.

lemuba commented 4 years ago

Ok, just as info - after installing rsyslog, I recognized that all my logs as syslog and user.log are mouted by standard to a 50Mbyte RAM partition and deleted hourly. So not poluting my system;-) If you need anything else, let me know and I will initiate - beeing happy and thankful that you develop this driver!

The best way to convert Lux to W/m2 is to divide by 126.7 https://help.ambientweather.net/help/why-is-the-lux-to-w-m-2-conversion-factor-126-7/

gary-hammer commented 4 years ago

Here's where I get lost. To my eye, it seem that 'light' is being found and parsed by the driver. Yet, weewx fails to use 'light'

gjr80 commented 4 years ago

I have looked at the raw data coming from the GW1000 and what the API defines as light (I will refer to it as refer to it as illuminance) is the only 'solar radiation' related observation being emitted by the GW1000. Given this and the linear relationship between the radiation values observed on the console and illuminance values from the API included in some posts on weewx-user, it is fairly clear that the GW1000 is dividing illuminance by 126.7 to produce radiation for uploads to the likes of WU and other weather sites.

Unfortunately this radiation value is not available via the GW1000 API. The GW1000 driver could calculate and emit it, but that is not the approach used by WeeWX drivers. WeeWX drivers take what data they can obtain from the station, decode and convert units if necessary, and emit that data for WeeWX to process. The driver does not derive observations. WeeWX has the StdWXCalculate service for calculating derived observations plus the StdCalibrate service can also be used to derive observations that are simple in nature. In this case radiation is a derived observation and needs to be derived by WeeWX. Given the debate over whether you can accurately derive radiation from an illuminance value, I am not sure we will see StdWXCalculate deriving radiation from illuminance. That leaves StdCalibrate, fortunately StdCalibrate can easily be configured by the user to calculate radiation from illuminance. Something like the following should produce a field named radiation from the GW1000 light field:

Correct.

Yet, weewx fails to use 'light'

What makes you think that? The log extract posted plus the --live-data output all show driver emitted data only, they do not show actual loop packets/archive records emitted by a running WeeWX instance. I suggest you run WeeWX directly and observe the contents of the loop packets and archive records. Do they contain light and radiation? If they contain light and not radiation then we have a problem and further investigation is required.

gus70 commented 4 years ago

The way that the Lux sensor is intended to be used is to divide by 126.7 and then the user can adjust the gain on the console for their location. Just take in Lux and divide by 126.7 and slap W/m² units on it and call it a day. There is your solar radiation. Yeah it isn't perfect...but the idea of the driver should be to replicate what the console does. You want the numbers to match. It is what it is. A Lux sensor is no substitute for a proper solar radiation sensor but that is what we have to work with.

They do not contain light nor radiation. They do contain luminosity

Understand what is happening, but the role of the driver is not to replicate what is on the console but rather to take what data the station provides and provide that data to WeeWX. The WeeWX services can then synthesise whatever derived data may be required. The decision was made some time ago, for a number of reasons, that WeeWX drivers would not derive observations.

They do not contain light nor radiation. They do contain luminosity

Ah, my mistake, the wview_extended schema shipped with WeeWX includes field luminosity so the default field map maps the 'light' value from the GW1000 to luminosity. The StdCalibrate stanza needs to be adjusted accordingly:

[StdCalibrate]
    ....
    [[Corrections]]
        ....
        radiation = luminosity/126.7 if luminosity is not None else None

Bingo! That was it. Now, if we just get some rain, I can finish testing all sensors.

gus70 commented 4 years ago

Excellent! Good work finding radiation = luminosity/126.7 code. Understood about the driver not deriving values. Glad this functionality was already in the wview_extended.

Many thanks, also working for me. Now with the fixed and today counted rain and corrected wind direction, back there where I was before with the interceptor driver. :-)
