D'Addario Guitar Humidifier Tracking - Humiditrak - Bluetooth Humidity and Temperature Sensor to Monitor Guitar Humidification, Temperature, Impact

I have 5 of these and they all work.I live near Austin, with radically changing humidity dry to wet. This units are in 5 of my most admired and loved acoustic guitars. The are accurate, and give me data on all my guitars. At first I placed small tracker units in my guitar. But I didn't have time to track the data for Humidity and temperature. Now I check at least twice a week and I used my old back units to track the Humiditrack data. The Humiditrack is way more accurate, and all I have to do is to check the printout once a week and I know what is going wrong.These units are fantastic and saved at least on of my old Gibson ES-335's from a refinish job.Anyone with Vintage Guitars in South Texas should get on ASAP !I'm buying another one tonight.Larry

Had a problem finding the app to then download. Classic Droid owners beware. You need to have version 5.0.1 to be able to use the Droid app. Pretty complicated to upgrade phone to do it. I tried and my pnoe wouldn't download the apps I needed to. Thankfully, I figured out how to get it downloaded to my wife's iPad. However, you have to hold the iPad sideways to get the display upright. It doesn't auto-tilt; only displays in Portrait view. Kind of clunky. But the tracking is pretty sweet. Doubled up with the D'Addario humidiyng system, and it's tracked 47-49% RH since installed a week ago. Nice to be able to track temperature and RH and have a record of it.

This is a review about the tracker, not the packs…(The packs work pretty good.) I’m a loyal DA’darrio customer. I’ve used their strings for years and just got into these packs. I thought the tracker would be a pretty good idea for my expensive guitars. So I got two of these. First of all the App is unbearably frustrating and clunky. Maybe it’s better on android? But Apple folks beware. Setting the information to link the sensor with a guitar might take 15-30 minutes because the design of the app is so terrible. So one of these sensors was defective right out of the box. I couldn’t get it to connect to the app, nor could I get a blinking red light. I think the terminals for the battery weren’t working or something…it seemed to have more play than the one they did word. For the one they worked, it didn’t alright…but after a month I went to the app to check on the humidity in my case and it had reset. The battery was already dead. I’m not changing a battery every month, nor am I going to mess around getting the app back running. I’m buying analog hydrometer…I have to bend down and open up a case every couple days to check the humidity? So be it. First world problem. I wouldn’t recommend these at all. A waste of time and money. DA’darrio, stick to strings!!!

[UPDATE]The good news: The sensors seem to be working as expected. I received a notice on my home screen that I had low humidity for one of my instruments (see photo). The photo shows that indeed-- my humidity had fallen below 40% for 24 hours. I replaced the Boveda humidity packs and within about a day's time, the humidity had gone up and has stayed above the 40% mark.The other news: In the app and under "What's New" you still see "Sensor Updates Coming Soon" which still indicates they'll arrive in a few weeks, same as before. The sensors and app have been in operation since end of November 2020. Nothing new to see. Not holding my breath.****[ORIGINAL REVIEW]Basically, this does as you'd want: monitors the humidity and temperature for your precious wood musical instrument. As a bonus, it will tell you if your instrument sustains some sort of physical shock.D'Addario does provide a quick start guide, which would lead one to believe there is more documentation to be found somewhere. Let me save you a load of time looking for it: there's not.You'll need to download an app. Under "What's New" the app trumpets "sensor updates coming soon!" within a few weeks. Not sure what that actually means. I will update if/when they arrive.So to begin, it's very easy to get it going, by just placing the item on your phone, where you've downloaded the app. (Follow the directions provided.) It did sync pretty quickly. Then the hard part comes. While you'd think it would be intuitive to populate your information, it really isn't. It took me nearly 45 minutes to insert the date I acquired my instrument, which I finally did by typing it in my notepad, copying it, and then pasting it into the app-- which didn't work anyway. If you look at the photo (with the red x's) that's what you get to somehow change the dates. I literally figured out today if I tap in the places indicated by each x, I can select the month, day, and year-- each one, one at a time. You'll feel the haptics when you 'scroll' in those spots.Similar problem to customize the brand-- no apparent way to insert something other than a typical brand (many listed as you scroll through). I eventually typed the brand in my notepad, copied it, selected one of the random brands available, and pasted my brand over it. (Which for reasons that are not clear, I THEN got a pop-out at that point asking me to supply the custom brand name. Sheesh.)How often does it update? well, about once an hour. How did I figure that out? just kept waiting until it did. Checked before I went to bed. Checked again in the morning. Checked later in the day. Indeed, it is getting a reading about every hour. (See photo with humidity being tracked.)When you open the app in range of your instruments (see discussion below), you get the welcome screen with the spinning gear (see photo). It then opens to the page that lists your instruments, and if you watch closely you'll observe the Bluetooth icon light up for a moment. You can then see an overview with current readings, and if you tap on the instrument, it will take you to a more detailed page where you can look at both temperature and humidity, either by the hour, day, or month. Both of those measurements appear to be relatively correct (they were kinda wonky when I first fired the up the device but have now settled down) and are more or less matching the larger room humidity/temp monitor I have in the room. It will theoretically notify me if the temp or humidity is out of the set range for a sustained period of time, but I have not found how "sustained" is being defined, and anyway (see discussion in paragraph below) it can't really do it unless I'm in the room.Because it is only Bluetooth (i.e. it does not connect to your WiFi network) you won't be able to be out of range and get updates, so if you think you can use this to monitor you instruments at home whilst you are on the other side of the world (or heck, even the coffee shop down the street) this is not the device for you. If you want a good way to make sure your instrument is being kept properly, and can be in the room to periodically check in, this should do the trick.You're welcome, D'Addario.

Purchased the Planet Waves Humiditrak - Bluetooth Humidity and Temperature Sensor - PW-HTK-01 and received it in January 2021. After 3 months of usages, the sensor stopped working and gives an inaccurate reading. Disappointed. What is the warranty period?

È riuscito ad aumentare il tasso di umidità dal 38 al 45% in poche ore! Ottimo prodotto!!

El Humiditrak es un sensor que transmite vía Bluetooth a tu smartphone dos datos críticos en tiempo real: humedad y temperatura dentro del estuche (o funda) de tu guitarra. Simplemente establece los rangos de tolerancia y en cuanto detecta que se rebasan manda las alertas correspondientes. Las lecturas se hacen con la App Humiditrak al estar cerca y también se actualizan los datos históricos para tener un control de temperatura y humedad en el tiempo (admite hasta 8 transmisores a la vez). Es simplemente genial y para el clima de la Cd. de México se vuelve indispensable para evitar que tus guitarras acústicas (mucho más sensibles a esos cambios) sufran en temporada de lluvias con humedades superiores al 60% o en época de calor con el clima seco que perjudica las maderas. Los rangos de fábrica son 40-60% de humedad, que me va bien y deja como un 5% de tolerancia antes de que se vuelva crítico, y de 4-30 grados Centígrados para temperatura, que para nuestro caso considero que 5-25 funciona mejor y da tiempo para reaccionar y alejar tu guitarra del calor. Yo lo uso junto con los Humidipacks de D’Addario y me sirven para monitorear su desempeño. También sin humidificador para controlar la humedad y temperatura dependiente del ambiente.Además ofrece la opción de transmitir una alarma de impacto cuando se exceden las g’s preestablecidas, aunque esta opción consume mucha pila y es mejor activarla cuando viajas y no cuando tienes guardadas y estacionarias tus guitarras. Simple y efectivo, sirve para cualquier guitarra, incluso de cuerpo semi-hueco o sólido que atesores y quieras cuidar como la niña de tus ojos. Indispensable cuando sales de viaje o gira con tus guitarras.

Ich habe 7 Humiditraks im Einsatz.Die Humiditraks sind gut verarbeitet und die Idee die Humiditraks per Velcro an eine Metallspange zu befestigen, die dann im bzw. am Gitarrenkoffer angebracht wird, ist sehr gut.Relative Feuchtigkeit zu messen ist nicht einfach und wer sich näher damit beschäftigt weiss, dass Messgeräte regelmässig unterschiedliche Werte auswerfen. Daher habe ich gar nicht erwartet, dass die Humiditraks genau funktionieren, allerdings weichen die von mir erworbenen Traks bis zu 8% untereinander ab. Von 7 Traks haben 4 Abweichungen bis zu 8%. Das ist mehr als vom Hersteller als Abweichung vorgeben und wenig hilfreich wenn die ideale Feuchtigkeit in einem Korridor von 10% liegen soll.Wie habe ich gemessen: Mit der sog. Salzmethode - Feuchtenormale. Unter Laborbedingungen habe ich 75% rel. LFK erzeugt und sowohl TFA Dostmann Präzisionshygrometer und die Humiditraks 'quasi' geeicht, sprich die Abweichung pro Gerät ermittelt. Wo die TFAs durch die Bank weg bis auf 1% Abweichungen ergaben, wichen die Humiditraks deutlicher ab (bis zu 8%).Ich habe aber die Traks dennoch im Einsatz um überhaupt Daten zu haben. Ich habe in der iPhone App hinter jedem Instrument die Korrekturwerte vermerkt, z.B. Gitarre 1 (-4), so kann ich sofort erkennen, auf welchen wirklichen Wert ich achten muss.Ferner funktioniert die Idee, ein iPhone/iPad zuhause per App mit den Instrumenten verknüpft zu haben und aus der Ferne über die Cloud auf die Daten zuzugreifen nicht. Die Humiditraks senden wann sie wollen, nicht wann ich es will.Ergo - tolle Idee, nur für die sehr ungenauen Werte und die Abweichungen max 3 Sterne, eigentlich nur 2,5 !Wenn D'Addario/Planet Waves eine gleichmässigere Genauigkeit und den Zugang via Cloud hinbekommt, dann ist das System 5 Sterne wert, vorher nicht. Da sind 3 Sterne vor dem Hintergrund der Kosten bereits eine großzügige Bewertung.

This device is very simple to use. I downloaded the IOS app to my iPad, removed the plastic battery protector tab and placed the device on the screen. Within a minute or so I had connected and it immediately gave me the first reading of temperature and humidity.As someone who has spent a lot of money on guitars and travels frequently, this unit is going to be invaluable to ensure that I or anyone else causes damage during transit or storage. Of course it isn't just limited to guitars, you can customise the limits and warnings depending upon your needs so I guess this could be used for anything which needs a controlled environment.The impact sensor uses more batteries so it is suggested that it is turned off when not in use, and the sensor will store readings for up to 21 days if you are out of Bluetooth range.It is a lot smaller than I expected (see photos) but this is ultimately a good thing.
