Cayenne issue on Adafruit Huzzah with luminosity sensor TSL2561

Community Help With My Project

Adafruit Huzzah + TSL2561. No data displayed on Cayenne dashboard.

Log:

[xxxxx] <msg xx,xxx,xx
<vw3lum,lux=%.3f - reply form Cayenne.luxWrite?
127.00 lux - this is read actual data from sensor

Where is issue ?

Hi there @viktoras,

It would be most helpful if you could post your code, since I’m not sure what the issue is yet.

Thanks!

Hi There,

I have the exact same issue. Not sure what is happening here. Do you know of any solution.

Thanks

@viktoras @soubir wanted to follow up here.

Perhaps you can reference these posts to help get the TSL2561 sensor working?

Hi @bestes,

I couldn’t get it to work on esp but got it working on a raspberry pi.
