Maybe you can try Buienradar lua script viewtopic.php?f=61&t=22010
I think that one is easier to configure.

Hi!!

I mentioned that the output of buienradar changed. When its going to rain the output is very light, like 0,1 mm but its raining hard outside, even like last night. So i checked the log and saw this:

It seems the output changed from xx.xx to xx,xx (comma) and the scrip takes the wrong position (see linetime).
How can i fix this ? :D

edit: found it already on this post: viewtopic.php?f=61&t=22010&start=80

Probably the same issue as I solved here: viewtopic.php?p=257405#p257405
Would have to see the script you use the give an exact solution.

edit:
Now it works maybe for a few minutes. Didnt change anything:

Maybe it has something to do with the first lines from the previous output.

As you see the rain value is 92 while the file contains 92,2678801510292.

... Ah i see the issue... you need to get rid of this line in the code as that screws up the just correct retrieved rain value.

Code: Select all

rain=tonumber(string.sub(tostring(line), 0, 3))
