The Things Network - odd data in Cayenne Dashboard

LoRa The Things Network
1

Hi,

I have a microchip lora mote, successfully transmitting payloads to a TTN gateway (which I have set up). The TTN end of things looks Ok to me. The mote collects luminosity and temperature. Here is what the mote LCD shows …

This is what appears at the TTN Gateway

This is what is on the Cayenne dashboard …

737×1355 58.9 KB

I see a lumonisty of 107 and temp of 29 being transmitted and received (encoded as 31 30 37 20 30 32 39 00) - so not at all sure what is ending up in the dashboard !

DevEUI is 0004A30B00197747
Cayenne Username is pat.molloy@outlook.com

Any ideas ?

Thanks,

Pat

Hi @pat.molloy, welcome to the Cayenne Community.

I want you to know that we saw this and haven’t forgotten you, I just need to get ahold of our LoRa expert for some questions about the decoder before I can properly respond here. If I can’t grab him today, I should have a chance tomorrow during the US workday.

Ok! Found him quicker than I expected. :grinning:

Long story short, you helped us find a bug in our decoder for this device. We’ve already corrected it on our production site, and now see the data that matches what you were expecting:

[
    {
        "channel": 0,
        "type": "lum",
        "unit": "lux",
        "value": 107,
        "name": "Luminosity"
    },
    {
        "channel": 1,
        "type": "temp",
        "unit": "c",
        "value": 29,
        "name": "Temperature"
    }
]

So I humbly ask if you could try again, and see if you’re now seeing expected values in your Cayenne Dashboard.

What can I say. Genius !!

It works a treat now …

Frankly, it is nothing short of miraculous that this all works with so little pain … good job :slight_smile:

Thanks a million for super support !
