ThingSpeak and Things Stack for LoRaWan Connected Devices
ThingSpeak includes an integration with The Things Stack to support collection of data over a long range network. I made a short presentation for this upcoming conference that shows you how to add the ThingSpeak integration to your Things Stack project. The agenda seems to be filled with other useful IoT talks. Here is the information on the conference:
Discover the next-generation #LoRaWAN deployments at The Things Stack Conference. Explore advanced LoRaWAN features, cloud integrations and the next-generation #IoT devices at #TheThingsConference - TheThings Stack Edition, online on 28 May 2021!

Hi Christopher,
Thanks for the video.
I'm modifying from the sample shown in your video (3:53) to upload battery data to ThingSpeak channel.
function decodeUplink(input) {
var b = input.bytes;
var battery = (b[0] << 8) | b[1];
return {
field1: battery
};
}
Did I get it wrong? Seems like I'm unable to send anything over, and the Test Decoder tool shows this "{}".
After changing to the following (reference to documentation):
function decodeUplink(input) {
var data = {}
var b = input.bytes;
data.field1 = (b[0] << 8) | b[1];
return {
data: data
};
}
I got this from the Test Decoder tool:
{
"field1": 3876
}
I do see entries in ThingSpeak channel, but the data field appears to be empty or invalid.
Could you advise?
Thanks.

Thanks for sharing your code. I'm not totally clear what the issue is. I know the code I show in the video works for my channel. Ill try sending data from the functions you shared to my channel and see what is happening.
Hi Christopher,
Thanks for your response. Your video is really helpful. I've managed to get it working using this code:
function decodeUplink(input) {
var data = {}
var b = input.bytes;
data.field1 = (b[0] << 8) | b[1];
return {
data: data
};
}

Ill have to fix the video. It seems my working decoder is coming from an old v2 application. Thanks for sharing and helping me get it right!
The conference is over, but you can still see the video I created. All the other interesting talks at the conference are also available.
Excellent video!
