[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.
