WiFi Temperature Humidity Sensor for use with AWS stops send data after an hour


We recently purchased WiFi Temperature Humidity Sensor for use with AWS (WiFi Temperature Humidity Sensor for use with AWS®) and set it up using the official guide.

But the sensor works unstable: it stops sending data to our AWS account after an hour.

It will continue to send the data if we unplug it from the external power and then turn it on again. But next, we will see the same issue: just about an hour - and it will stop sending data.

Here is the screenshot from AWS IoT Monitor:

Could you please help?


I checked another sensor - it works the same way.

Note: when the sensor stops sending the data, the onboard RGB LED indicator starts to glow green constantly. Instead of blinking green.

Could you advise?


I will setup a test and look into this today.

I was able to replicate the issue you are seeing. Looking into it now. Once resolved I will provide instructions to update firmware on your devices.

Thank you, Travis! Will wait for the update


I just did some testing with some firmware changes and the connection appears to now be stable. Try updating the firmware on your devices using these instructions:

Let me know what you find.

Thanks, Travis!

I’ve just updated the firmware. Will let you know about the results
