- Sat Dec 05, 2015 8:11 pm #35775 I'm trying to use the SENDTS function to send ThingSpeak a floating point number (a temperature value actually)

When I do this: SENDTS("APIKEYHERE",1,tempF), the data doesn't get logged on ThingSpeak. But, when I use SENDTS("APIKEYHERE",1,"1"), the value does get logged (as it's a hard coded string). Is there a way to convert an integer to a string so this value can be sent? I also tried this: SENDTS("APIKEYHERE",1,"'" & tempF & "'"), but no dice.

- Sun Dec 06, 2015 1:38 pm #35819 Funny enough for me when i tried yesterday:

Code: Select alltemp 0 curr
    SENDTS(APIKEY,1,curr)

Worked perfectly but then

Code: Select allSENDTS(APIKEY,2,"1")


Did not. But i think in my case, as i tried to send them quickly eachother ThingSpeak api did not record it because there is time limit that you can only upload data every 15sec.

Doing stuff. Doing things. Most of that you'll find from my blog.

- Mon Dec 07, 2015 2:49 pm #35903 I'm using the Themometer example from the BASIC website, but here's my modification for the [refresh] subroutine with trying to send the data to ThingSpeak.


[refresh]
tempF = 0
temp 0 curr
let tempF = curr * 1.8
let tempF = tempF + 32
SERIALPRINTLN tempF
SENDTS("6DWOBDYDGIPQP4AC",1,tempF)
if tempF < setp then goto [on2] else goto [off2]
Wait


The result on the thingspeak side is NAN.

If I use:
bla = "api.thingspeak.com/update?key=6DWOBDYDGIPQP4AC&field1=" & tempF
print wget(bla)
cls

This works fine.
