In reply to Skipper.

I will look into it. Let me know if you try it.

Hi.
Is ThingSpeak also compatible with the new “Arduino Uno Wifi” ABX00021 ?
Best regards Skippers

Hi Venkatesh,

Version 1.0.6 is really old, please update to a more recent version of the Arduino IDE.

The ThingSpeak library isn’t visible by default. You will first need to add it by going to Sketch -> Include Library -> Manage Libraries. Search for ThingSpeak and install the latest library from there.

Hi ,

I am a first time user of ThingSpeak. I use Arduino Mega 2560 with IDE version 1.0.6. It does not show ThingSpeak library. How do I update ?

Kindly suggest.

Regards.

Connection to ThingSpeak failed (1)

Connection to ThingSpeak failed (2)

Connection to ThingSpeak failed (3)

Connection to ThingSpeak failed (4)

Is there any way to check that writing data to TS was successful? I’ve got two ESP8266 based boards reporting temperatures to the same channel with a 180 second delay. Due to hardware timing inaccuracies they slowly drift until one is trying to write data within 15 seconds of the other causing it to fail with gaps in my data.

Hi,

I’m trying to install the library with an Arduino Mega and CC3000 wifi shield … but i get lots of errors if I put this in the code: #include “ThingSpeak.h” (I’ve not made any calls yet)

\Documents\Arduino\libraries\thingspeak\src/ThingSpeak.h:86:8: error: #error Only Arduino Yun, Uno/Mega/Due with either Wired or wi-fi Ethernet shield, ESP8266, and Spark Core/Photon/Electron are supported.

\Documents\Arduino\libraries\thingspeak\src/ThingSpeak.h:1469: error: integer constant is too large for ‘long’ type
\Documents\Arduino\libraries\thingspeak\src/ThingSpeak.h:1469: error: integer constant is too large for ‘long’ type

etc…

Is it just not compatible?

Hi,

I am trying to install the ThingSpeak arduino library, but it is not listed in the arduino IDE’s “manage libraries.” I am using arduino IDE version 1.6.7 under Windows. I searched for the “library_index.json” file, but there is not such file in my system. Is there any other way to install this library?
Thanks.

Thanks for the examples. My current project is to use ThingSpeak to log and visualize my residential water use. I’m stuck trying to find or create a Sketch that will enable my Ardunio with Ethernet to write a single byte Field1 representing my water use in gallon every 20 seconds.

I Attempted to use the Write Voltage example but I’m having a problem making ThingSpeak.writeField work with the output of my counter Sketch which is a Volatile Byte data type. I am using digital pin 2 as my sensor input and tried to success no but n I try to wheserialwrite to a serial

Hello,

I am wondering if there is a way to set the parameters for the time for seconds instead of minutes for more data points.

Thanks.

No, not compatible with ESP8266 client. Got this error:

This library is great. I only miss thinghttp support. Is there an easy way to extend this to cover thinghttp?

Hi all,

Version 1.1.0 of these libraries now supports ESP8226 devices, the Particle Electron (coming soon!).

You can use these libraries directly from within the Arduino and Particle IDEs.

All the best,

In the Particle Photon Library I can’t get the last two examples WriteMultipleVoltages and WriteVoltage (the ones I need) to compile. I get the following error:

In function `ThingSpeakClass::convertFloatToChar(float, char*)’: ThingSpeak/ThingSpeak.h:1444: undefined reference to `dtostrf(double, signed char, unsigned char, char*)’

The other examples compile fine. Can you fix this?

Thanks!

In reply to Stephen.

I’ve found that sometimes the Arduino IDE caches this info, and then doesn’t always update. Assuming you’re using windows, if you go to the AppData/Arduino15 directory, there’s a file called library_index.json. Quit the Arduino IDE, delete that file, and start it up again, and you should be all set.
On my computer, this file is at:

Hi all,

There some good conversations and common issues that people encounter over in the forums:

I have 1.6.5r5 installed and there is no ThingSpeak library when checking manage libraries.
