I need some help.......

I'm trying to get the info from Wunderground to show on a weather station I'm building
I can get it to work fine using openweathermap.org but I can't get Wunderground to work and Wunderground has a lot more data available

Anyone able to help?

This is what works with openweathermap
[code]timesetup(1)
print time()
delay 1000
print time()
timer 10 * 1000, [RUNPROGRAM]
wait
[RUNPROGRAM]
cls
PRINT "TIME" & "," & time()
serialprintln "TIME" & "," & time()
let query = "api.openweathermap.org/data/2.5/weather?q=Denton,uk&lang=en&units=metric&appid=API_KEY_HERE"
delay 500
let ret = wget(query)
let temp = json(ret,"main.temp")
let press = json(ret,"main.pressure")
let humid = json(ret,"main.humidity")
let speed = json(ret,"main.speed")
speed1 = int(main.speed + 0.5)
let dir = json(ret,"main.deg")
let icon = json(ret,"main.icon")
let desc = json(ret,"description")
println "Today," & desc & "," & icon & "," & temp & "," & press &"," & speed1 & "," & dir & "," & humid[/code]

This is my code for Wunderground but it fails on LINE 22

[code]timesetup(1)
print time()
delay 1000
print time()
timer 10 * 1000, [RUNPROGRAM]
wait
[RUNPROGRAM]
cls
PRINT "TIME" & "," & time()
'println "TIME" & "," & time()
let query = "api.wunderground.com/api/API_KEY_HERE/conditions/q/UK/Audenshaw.json"
delay 10
let ret = wget(query)
let temp = json(ret,"temp_c")
let press = json(ret,"pressure_mb")
let humid = json(ret,"relative_humidity")
let speed = json(ret,"main.speed")
speed1 = int(wind_mph)
let dir = json(ret,"wind_degrees")
let icon = json(ret,"icon")
let desc = json(ret,"wind_string")
println "Today," & desc & "," & icon & "," & temp & "," & press &"," & speed1 & "," & dir & "," & humid
[/code]

This is the actual full return from the API call that I'm trying to parse

I'd like to get this working so I can then work on the forecast which again works fine in openweathermap*
Thanks in advance

I've hardly used it but I don't think it has println. Just print.

Haven't used it myself either
but just looking at it
10 has 'printin
22 has printin

9 has a print statement with 10 having the same worded 'printin after it

22 doesnt have a print statement before it anywhere I noticed

could either of these be the issue?Edited by Boppa 2017-04-09

The println just means it prints to the console and puts a line return after printing
Print prints with no new line

whats with the ' in front of it?- does that have any special meaning
(its been years since I played with this stuff- about 30 in fact)

the ' means ignore that line, It was there in a previous version I forgot to remove
' instead of REM (not sure rem works)

ok that explains that then (sorry its been a while and I started on applebasic, then commodore basic, then microbee, back to commodore, then various gw/ms/tandy basics- all had their own little quirks)

one other thing I just noticed, in 22 in the middle is this bit

press &","

in the middle of this

temp & "," & press &"," & speed1 & ","

??? maybe this

(no spc between & and ")
ie press &"," should be press & ","
???

Lew I think the clue to the problem is the in the error line

I suspect that there is too much data comming back from WeatherUnderground for ESPbasic to handle, its a bit flakey handling large streams of web data i think, thats why the Openweather command has arguments to parse portions of data.

Ah... I never actually considered that, it makes sense actually as there is a lot more data than Openweather
Shame as it would have been a better option for those who don't have an actual weather station to get the live conditions from
Thanks Mike
