number of raindays in a period. **solved**

[Gyvate]

I am looking for retrieving the number of raindays (respectively the reverse: the number of days without rain) in a period with Meteobridge:
all time, year, month, weewx, from - to - but I could find anything in the Template section of the WiKi which touches this point.
Also, searching in the forum didn't produce anything useable ...

I know that technically I would have to count the days when the daily rain sum was bigger than a defined threshold (>0.00, >0.1 --> dew, ...),
but how to formulate it ...?

two questions:
1. for determining the number of raindays in a given period (from - to):
Does anyone have ideas what the expression [sensor-selector ...] has to look like ? Maybe in combination with a conditional expression #if ...#fi

2. Is there a possibility to create a loop with a break condition (e.g. loop while condition is fulfilled or loop until condition fulfilled with the template language) ?

[Gyvate]

is the solution to this question so trivial that noone of the experts minds to answer ?
I would at least expect from @admin a statement like
a) can be done e.g. this way or that way
or
b) not possible with MB means ...
or
c) a respective variable will be created to be used in the template language.

I hear that under Meteohub this is possible ...

Hello,
yes, you are right. Meteohub had this function.
I don't understand why Meteobridge, as the successor, can do less than its predecessor.
I would also like to have these raindays.

[admin]

Meteobridge has a completely different handling and storing of data compared to Meteohub. This is to get rid of delays in finding min/max values and ineffective data handling. To believe that a completely new designed follow-on product does clone every single feature of the former one is not realisitic. Nevertheless, I will think if/how to support wishes like "count all years/months/days/hours that meet a certain sensor condition".

[Empire24]

Thank you very much for the feedback, which is absolutely understandable. I appreciate your willingness to consider implementing this through an update. Ultimately, the end customer is only interested in the result and does not understand the process behind it.

[admin]

I implemented a light version of this, which hopefully lowers your pain a bit. Please read here: https://meteobridge.com/wiki/index.php/Forum

[Empire24]

Thank you! Works wonderfully
The only thing missing is that "@" works.

[admin]

Just did a rework of the solution. New syntax and function can be found here: https://meteobridge.com/wiki/index.php/Forum
I will check tomorrow how to make this available in exports as well.

[admin]

I also added support of day counts in exports via "rain0total-count" template variable. Please have a look at the modified "NOAA" template below, which adds number of rain days as a last column:
