New evapoTransp block ( evapotranspiration )

[davidefa]

I converted the et plugin in a block.
It uses the local recorded data ( temperature, humidity... ) to calculate evapotranspiration ETo for current date, current location ( see the plugin documentation for more info ).
If you don't have a solar sensor you have to define the solar radiation in the block setup.

Thanks for the conversion to a block.

I think there is something wrong with the SQL statement.
Because in the statement there are these lines:

Code: Select all

GROUP BY Year(DateTime), Month(DateTime), Day(DateTime)
			ORDER BY DateTime Desc
			LIMIT 1

So, whatever period you specify it will always select the data from the last day and not the average from the complete period.

I think that the complete SQL query should look something like this:

Code: Select all

SELECT avg(T), avg(H), avg(P), avg(S), avg(W)
		FROM alldata " .
		$span

Hi Asobig, thanks for the hint. I corrected what you reported and added a few option.
As shown in the image the block shows the evotranspiration:
- of a few 'periods' in the past ( using the data recorded by the weather station in the past periods ), ETo(-n day) in the image
- of 'today, last 24h' ( using the data recorded by the weather station in the past 24h ), ETo(24h) in the image
- of 'today, forecast' ( using the data recorded by the weather station from past midnight till now and forecast from yr.no from now till next midnight ), ETo(f) in the image
- a couple days in the future ( using the forecast from yr.no ), ETo(f+n day) in the image
This to help having an overview of the evolution of the evapotranspiration, and a better evaluation of today's value
