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.

Can you let the full code. It should be working with vatlriables for any functions parameter.

Funny enough for me when i tried yesterday:

Worked perfectly but then


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.

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.
