Musical instruments can be easily damaged by large and rapid changes in humidity and temperature. Now you can protect your investment by simply placing D’Addario’s Humiditrak or TKL's Safe & Sound with Blustream Technology inside your instrument or case.

Humiditrak and Safe & Sound use a patent-pending Bluetooth sensor to provide a constant stream of temperature, humidity, and impact data to the free smart phone app to alert you of hazardous conditions that can lead to diminished playability, costly repairs, and lost value of your instrument. When Humiditrak detects dangerous conditions, notifications are sent to all your devices allowing you to take corrective action before damage occurs.

Cataloging and monitoring a collection of instruments is so easy and convenient, you’ll want one for every instrument you own! D'Addario is known for innovative, problem-solving, quality musical accessories. D'Addario accessories offer a complete line of award-winning accessories including cables, picks, tuners, capos, straps, humidifiers, maintenance tools and more.

It forgot who I was

UPDATE. I have never had a developer respond to a review before. I am very impressed with their desire to address my comments and my problem. Consequently, I have up upgraded my rating. The app does work quite well and I am still very pleased with the data it collects and the ease of use. Other than the hiccup I encountered with logging on, the app has performed perfectly. I have every intention of continuing to use my Humiditrak and this application. Thanks!

After nearly 2 years of use, my app stopped recognizing me. It required me to log in then wouldn’t accept my password. Then all I got were error messages when I tried to reset my password. I could find no way to contact any form of customer support. I even tried to uninstall and reinstall the app.

The only way I could get my device working again was to set up a new account with a different email. Now I lost all my historic data but I was able to get the Humiditrak working.

While I still like and still use the device I was disappointed of the process I had to go through to restore my device to working order and the inability to contact any type of customer support when the automated password restart failed.

Turned into brick

When you buy a device like this you expect it to work.

—update just received reply from the Dev team at big D. Was it 90+ days later. That may sum up the support the give to clients.

— if you love you instruments get something that is reliable and easy to use. Sensor push has been working flawlessly and works on Wifi give constant updates.

I found this device has limited Bluetooth range . Also device stopped working after 4 months. Support said unit had issue during upgrade and did not complete software load. Support sent a set of instructions for potential error. Instructions do not fit my issue since it does not light nor connect to Bluetooth. In hind site should not have wasted my money.

On the other hand My SensorPush device has worked flawlessly with better range(WiFi) remote alarms etc... very useful vs Humiditrak extremely limited offering

Developer Response

We apologize that we were not clear on the purpose of the instructions that were sent. One of the symptoms of a failed sensor update is that it will not connect or blink. The instructions sent included a link to reset the sensor that would allow the update to proceed.

In addition, the latest release of Humiditrak, version 1.4.2, provides improved connectivity.

If you have any questions or issues, please contact us at support@blustreamcorp.com.


Working Great!

It was very easy to get set up. I did have to look at a lot of the website pics to see where they installed the device at in the case. Would like a suggested install in the user manual. The app loads great and is tracking everything! Thanks for making this device!
