Need help with getting info from a string with live rain website

[kooy 5]

Hope you guys can help me.

 

I found a website that can give you realtime rain info on a specific lat and long values.

 

It can predict rain in your area upto 2 hours upfront.

 

now my only trouble is how to get the right info from the website.

 

As it stand now im getting info like this

 

000|20:50 000|20:55 000|21:00 000|21:05 000|21:10 000|21:15 000|21:20 000|21:25 000|21:30 000|21:35 000|21:40 000|21:45 000|21:50 000|21:55 000|22:00 000|22:05 000|22:10 000|22:15 000|22:20 000|22:25 000|22:30 000|22:35 000|22:40 000|22:45 000|22:50

 

where 000 is the amount of rain and timestamp (lucky me no rain at least till 22:50)

 

What i would like is to get the info only for the next 15 minutes.

so if my local time 21:15 i would like to get the info for 21:30 which looks like 000|21:30

 

How to get the 000 part out of the string at 21:30?

 

i tried

str = string.match(response, "21:10")

fibaro:debug(str)

but that only get the me right time and i need the 3 chars before that.

All, (draft note)

 

I think I got it working again (very beta code) , it is a combination of old buienradar (thanks to

!) and the code from 

Please login or register to see this link.

  (thanks guys !)

 

Working progress / tot do:

- generalise the the scene as I have added soms "persona extensions" / modifications.

- rebuild the -> function latlon() -> (for now hard coded in scene)

- restore error messages -> disabled most of them

- cleane code _> code is still a mess, was not the first priority

- implement the self-run so it will refresh's every e.a 5 min -> for me not a prio as I use Sankotronic FTBE v 1.3.0 to schedule a refresh run every 5 min.

 

If people are interested or if we can find a way to work on this as a group I can share my (bata) work

Hi Twannie, this is a separate scene, and you need to "delete or disable" the code in the VD and I added the following code to the "refresh button" in the VD -> fibaro:startScene(442); -- start: Buienradar (refresh) Scene and replace 442 with the right scene number,

Thanks Patrick for sharing.

 

I copied your code into a new scene and adapted the VD number. The data is correctly fetched from the web-site after I added the global variable "Rain".

 

At this moment I got a fatal error at:

[DEBUG] 21:59:18: 000|23:55
[DEBUG] 21:59:18: nil
[DEBUG] 21:59:18: Check 01
[DEBUG] 21:59:18: 2020-08-18 21:59:18.018986 [ fatal] LUA error: /opt/fibaro/scenes/31.lua:164: attempt to call method 'sub' (a nil value)

 

Line 164:  rainT = responseTable:sub(1,3)

 

Any idea why the code at my side is not working?

 

Thanks, Quino

 

BTW which VD did you use?

Think I have solved most of them ..and everything is working fine (since this morning) 

[Twannie 33]

can you share the right code with vd at once to avoid mistakes?

[Patrick 11]

done, I have updated my code in earlier post (see above)

Hi Thanks and very interesting as I do not have this error myself 

[Twannie 33]

My mistake

 

I get this

23-Aug 13:08:13 : Selfrun activated (1212)
23-Aug 13:08:13 : update: latlon()
23-Aug 13:08:13 : 2020-08-23 13:08:13.913450 [ fatal] Unknown exception: /opt/fibaro/scenes/830.lua:99: attempt to concatenate a nil value

Edited August 23, 2020 by Twannie

[Twannie 33]

I noticed it is this line:

logbug("grey", "Rain: " ..fibaro:getGlobal("Rain")) 

I noticed the global variabele "Rain" is not created by the scene

So I created "Rain"

Edited August 23, 2020 by Twannie

[Twannie 33]

So now I get:

 

23-Aug 13:21:06 : 20200823 vBeta 0.2
23-Aug 13:21:06 : Status buienradar: 0
23-Aug 13:21:06 : Status Rain: 0
23-Aug 13:22:06 : Selfrun activated (1212)
23-Aug 13:22:06 : update: latlon()
23-Aug 13:22:06 : Rain: No
23-Aug 13:22:06 : End

 

But the VD stays empty so now updatetime or anything

You did create "Rain" too?

[Patrick 11]

Think I found the problem as some of the code gets disrupted when I copy this to this forum .. l have added a txt file with the full code
