Under MODULES there is a setting forPyETO Solrad behavior. It estimates either from temperature or sun hours or doesn’t estimate.
Under MAPPINGS I have set my sensor for Solar radiation. Could this be used instead?
if you set PyETO to not estimate, it will look for a solar radiation sensor in the mapping and will use that value. If there is none, it will use OWMs value (assuming you have OWM configured).
If you let PyETO to estimate from temperature or sun hours, it will not ask OWM for a solar radiation value nor will it ask a sensor for a solar radiation value, even if you configured it in the mapping.

I determine the weather data every hour, first update at 4:00 am The calculation of the watering duration is done at 11:00 pm.
How are the sensor measurements taken into account?
- Are the values collected over the day used (average, minimum, maximum, first last, etc.)?
- Or are the current measured values at the time of calculation
- or the last measured values before the calculation used?
It’s complitly gone. I don’t know know and why.
This is what you can configure in the mapping aggregates…
Not sure I understand
My wiki gots lost. 
But which values will be taken, the last updated value, or of all collected during the day?
When weather data like temperature are collected e.g. at 4:00 am it’s colder than during the day normally.
It’s simple really. Any values in weather data are taking. The aggregate is applied to them, so if you set the aggregate to max you will get the highest value, etc. After a successful calculate the data is wiped.

So a good practice would be to collect data over the day maybe every hour and not a single value e.g. at 4:00 am.
Next question regarding First Update. If calculation start at 23:00 and first update is 4:00 are there no value measured between 23:00 and 4:00?
That is correct
What sensor should be best for precipitation?
- event rain rate = last rain event
- daily rain rate = accumulated per day, reset at 00:00
- hourly rain rate = some peaks during the day
I guess daily rain rate would be best, if the calculation happens before 23:59 or taking the maximum.
I’d use daily and then set aggregate to max or last. You could also use hourly, collect every hour and set aggregate to sum.
Something for the wiki.
