Retrieving Weather Info at any Longitude or Latitude

General
1

I’ve been using a weather API lately to get the weather. It gives a summary, humidity, temperature, precipitation probability and much more! I’ve already parsed few things, you can continue to parse more if you choose. If anyone was interested they can check out my code:
EDIT: Many new things added and if you get an error then no weather information is available at that location

-- Weather

-- Use this function to perform your initial setup
function setup()
    
    parameter.text("APIKey","")
    parameter.integer("Longitude",-180,180)
    parameter.integer("Latitude",-90,90)
    
    --I registered an API Key that is free to use
    APIKey = "7687f8ec79fcbe92cdd91a9589262a12"
    
   
    parameter.action("Request Weather",request)
    
   
end

function request()
     coord = string.format("%f,%f",Latitude,Longitude)
   http.request("https://api.forecast.io/forecast/"..APIKey.."/"..coord,success)

@austinmccoy Nice program. Lot of room for adding more display information.

3

Thanks!

@austinmccoy I changed your program a little to make it easy to read all the data that’s returned from the request. You can easily see what needs to be searched for to display other information.


-- Weather

function setup()
    parameter.text("APIKey","")
    parameter.integer("Longitude",-180,180,-82)
    parameter.integer("Latitude",-90,90,41)
    APIKey = "7687f8ec79fcbe92cdd91a9589262a12"
    parameter.action("Request Weather",request)
end

function request()
    coord = string.format("%f,%f",Latitude,Longitude)
    http.request("https://api.forecast.io/forecast/"..APIKey.."/"..coord,success)
end

function success(Data)
    Data=string.gsub(Data,",","\
")
    Data=string.gsub(Data,"{","\
{\
")
    Data=string.gsub(Data,"}","\
}\
")
    print(Data)
end

Here is a modified version of Dave’s version which uses your current location by default:

-- Weather

function setup()
    location.enable()
    parameter.text("APIKey","")
    parameter.integer("Longitude",-180,180,location.longitude)
    parameter.integer("Latitude",-90,90,location.longitude)
    APIKey = "7687f8ec79fcbe92cdd91a9589262a12"
    parameter.action("Request Weather",request)
end

function request()
    coord = string.format("%f,%f",Latitude,Longitude)
    http.request("https://api.forecast.io/forecast/"..APIKey.."/"..coord,success)
end

function success(Data)
    Data=string.gsub(Data,",","\
")
    Data=string.gsub(Data,"{","\
{\
")
    Data=string.gsub(Data,"}","\
}\
")
    print(Data)
end

@JakAttak Nice going. I totally forgot about the location functions.

7

Nice improvements! It looks a lot better now.

8

@erickyamato I’m sorry, I forgot to remove parameter.action. It’s not needed, so I removed it from the above code. The way the code above is set up, it will check the weather when the minutes is at 5, 10, 15, 20, etc. So you might have to wait for the first check.

9

@erickyamato I wasn’t sure what you wanted from the request. That’s why I was only printing the first 400 characters.

10

Is there any way to request automatic?

I’m doing a game that changes the background using the weather

11

tween.delay could be doing it.

12

@erickyamato You can set up a loop that checks the time of day and every 15, 30, or 60 minutes it checks the weather.

13

@erickyamato Here’s an example that checks the weather every 5 minutes. Just change the 5 in td.min%5 to how often you want to check. For instance, 15 for every 15 minutes, 30 for every 30 minutes, 60 for every hour.


function setup()
    checkWeather=true
    location.enable()
    APIKey = "7687f8ec79fcbe92cdd91a9589262a12"  
    request()  -- request weather at startup
end

function draw()
    checkTime()
end

function checkTime()
    td=os.date("*t")
    if td.min%5 == 0 then  -- check every 5 minutes
        if checkWeather then
            checkWeather=false
            request()
        end
    else
        checkWeather=true
    end
end

function request()
    coord = string.format("%f,%f",location.latitude,location.longitude)
    http.request("https://api.forecast.io/forecast/"..APIKey.."/"..coord,success)
end

function success(Data)
    Data=string.gsub(Data,",","\
")
    Data=string.gsub(Data,"{","\
{\
")
    Data=string.gsub(Data,"}","\
}\
")
    print(string.sub(Data,1,400))   -- print the first 400 characters
end

Thanks @dave1707 @Jmv38

15

@dave1707 is there any way to start requesting the weather wihout pressing the button?

16

@erickyamato Pressing what button. The above code will check the weather every 5 minutes as long as the code is running. There’s nothing to press.

17

@dave1707 “Request Weather”

Can I use anything like parameter.boolean?

18

Ok!

Thank you @dave1707 !

19

@erickyamato I added request() in setup() above, so it will check the weather as soon as you start the program, then it will check at the 5 minute marks.

20

Thank you @dave1707 ! I just need to request the “summary”, to change the background…
