[Solved] Netatmo rainsensor amout during the day

Hi
I have one problem to get the amount of rain during the day using the Netatmo binding. When I get the data for the day from database the value will differ from the value shown in the Netatmo app (0.7 in OH vs. 1.1 in Netatmo). I currently do persistance for every change. Is there any problem with this strategy for this usecase?

Edit: After reading the doku again I’ve found the solution myself… So the correct response should have been RTFM.

Thanks & Regards
Dieter

Hi Dieter,

Did you see the latest additions I made to the Netatmo binding? The following should give you the sum for the day as provided by Netatmo:

Number Netatmo_Rain_Today “Rain Today [%.02f mm]” (Netatmo) {netatmo=“00:00:00:00:00:00#05:00:00:00:00:be#sum_rain”}

Hi Rob

Yes, I did. But only after I’ve posted the message.
But one question, as you are already here: The day values, go they to today until now or for the last 24 hrs?

Thanks & Regards
Dieter

It appears to be for the current day (00:00 - 23:59) in your current timezone. The documentation doesn’t provide much help. The specific calls to Netatmo are at: https://dev.netatmo.com/doc/methods/getmeasure

2015-11-17 07:21:01 - nRainToday state updated to 0.5910

Depending on the timing, the first reading of the day still might contain the results from the previous day. But I don’t think this will be a problem if you always use the latest value returned from the binding.

Hi Rob
Thank you for your help, this will solve my problem.
Even if I really want to know the last 24hrs, it shouldn’t be a problem to calculate them using persistance (especially when I don’t need 100% accurate values :wink: )

Regards
Dieter

Does this also work in openHAB2?

8

Good question. I would ask the same.

Did you get any answer on this?

I have no other idea how to show the amount of rain per day…

9

Unfortunately not. I didn’t find any solution for OH2.
@ranielsen: Is there any plan to implement this in the new binding?

Thx
Michael

Sorry, I can’t answer that.
