Boveda Smart Hygrometer for Humidors, Herbal & Music | Measures RH and Temperature With Auto Alerts to Your Phone | Easy-to-Use Calibration Kit Included | App for iOS/Android | 1-Count

Simply the best product I’ve bought for my cigar collection. Accurate, easy to use, fun. Since I’ve switched over to the Boveda packs, and the Smart Butler, cigars are always fresh. So much so I’ve added a number f expensive cigars to my humidor, +$90 a stick. I’m in the process of upgrading a second humidor and will add a second Butler. The iPhone app will see two Butlers and provide notifications for each. Great product, you will love it.

Bought it a month ago for my 250-cigar humidor. Works great and as advertised. When I calibrated it using the included calibration pack, it read 76% rather than 75%, but the app adjusted for that and it’s within the 2.4% accuracy range. I’ve been spot checking it and it’s been reliably tracking humidity and reporting it to the app on my phone. Gives me peace of mind.

does a good job but the bluetooth does not always work. Sometime you have to reset it to work.

I’m rewriting this review... I had several issues with my first Boveda Butler... horrible connectivity, terrible calibration and unstable readings 24/7...Bob from Boveda reached out to me and offered to send me a replacement unit... It was perfectly calibrated out of the box... stable readings... turns out I got a defective unit the first time...Regarding the connectivity... I own a Newair CC-300H for my CC... Boveda reps told me that the connectivity issues could be due to the wineador metal construction... I was advised to set up a second device and keep it close to the humidor... So I just used an old phone as a bridge and as a plus I get WiFi capabilities not just the Bluetooth...The ease of use and being able to monitor my temps anywhere is a huge plus... however it does require a spare device that not everyone has...Great customer service from Boveda!! I’ll be ordering another one for my NC humidor...

There are a lot of features to like about this. It's accurate, it keeps an hourly log of temperature and humidity readings that makes it easy to troubleshoot your humidor, if it spikes or drops at a certain time of the day or at the changing of the seasons. And most importantly, it does all this without you having to constantly open the box to check on things (thus degrading the equilibrium of your humidor).The only downside is minor and to be expected--because it's bluetooth, it'll eat through batteries (relative to other digital hygrometers). Where a Diamond Crown or Digital Oasis or what have you will last for years on a single battery, you're looking at about six months or maybe a little longer for the Boveda. If you buy this, also buy a handful of CR2032 batteries--you'll need them sooner or later.Overall, this is a little more expensive to buy and operate than a lot of other hygrometers, but you've got hundreds or thousands of dollars worth of cigars in your humidor. This hygrometer will take the guesswork out of trying to maintain them.

Great tool so great you never want to wait for the 24hour period to calibrate. I stopped 20 hours in and found out the hard way that I had to calibrate for another 24 hour period. Working well now and I like the ability for the app to notify you. Instructions on being able to remotely monitor are a bit confusing. By the sound of it, you need a device to stay home then you need to have that devise on wifi then have your remote devise talk to the at home device that’s talking to the unit. So many layers.

These little gems work as advertised. I have 5 and I calibrated each and none were off more than 1-2% on the humidity. You cannot calibrate the temperature but mine read 70, 70, 69, 70 & 69 in my study. I’m fairly confident my actual temp is between 69-70 and that’s plenty close for cigars.At $34/ea I think they are a little pricey, but they do use Bluetooth and the app is outstanding.

I like Boveda for what it is and it's products tend to not disappoint. However, this one isn't up to that standard. The app that it is paired with has some odd glitches. The temperature and humidity is different than eachother when viewing quickview versus viewing the chart. What I mean by this is you have a list of all of your boveda products or butlers and it quickly displays a temp. and humidity, tap on a specific butler and it pulls up a chart. The second thing that bothered me was the accuracy. During the 24 hour calibration the bags seal, on the bottom, had a slit in it or came unsealed. Since I was having problems with humidity readings I figured sealing it myself would fix it. It fixed nothing overnight during the acclimation process and the temperature was innacurate as well. Putting this thing in one of the colder parts of my house so the temp would read in the range it should, it didn't do a damn bit of difference. I'm starting to think I wasted my money on this which really sucks because I've never disliked a boveda product.Update (mar 25): The Boveda Hygrometer simply won't update at all anymore. The only way it will update is if I open my humidor and shake the crap out of it.

Lo calibre con su Boveda que trae para poder usarlo, lo puse como referencia en mi humidor pero estoy super confuso:-Los primeros 5 meses lo deje como mi única referencia para tener mis puros a 72% de humedad pero noté que los puros estaban perdiendo humedad y poniéndose cada mes más secos y duros en lugar de ese punto de "corcho" en el que deben de estar.-Noté que el higrómetro del humidor al principio coincidía con la boveda pero con los meses me marcaba que había menos humedad pero la Boveda marcaba entre 70-75.-Recalibre ambos para ver si pasaba lo mismo y seguía con discrepancias en las lecturas cuando Boveda me marcaba 72% el higrómetro me marcaba 60% y cuando ponía el higrómetro a 72% Boveda me marcaba la humedad en 84%-Compare con otro humidor más pequeño que tengo y aunque aunque no era tanta las diferencias daba lecturas distintas.-Decidí mejor comprar un higrómetro digital para una tercera lectura y obtuve igual lecturas diferentes el higrómetro digital me marcaba 70% el del humidor 72% pero Boveda 84%No lo recomendaría porque algunos meses mis puros estuvieron con menor humedad y la verdad estaban y están en mejor condición cuando uso el digital y el del humidor.

I gave it 5-stars as it works and does what it says... but since it uses bluetooth technology, you have to be in close proximity... If I am close, I might as well just open the box and look at my hygrometer.Also, the battery life is oddly short for a device that is really not doing much.Like I said, it's doing what its designed to, so 5-stars for that... Am I glad I bought? Meh..

After careful consideration,I wanted to review the butler. If you smoke cigars then BUY this.After seasoning my humidor with the seasoning kit from Boveda the butler is like an alarm system for your cigars in Canada our humidity is up and down,Boveda will ensure your humidor is running at optimal performance giving you warnings so you can correct any humidity or temperature problems instantly. After seasoning give it at least seven days to acclimate to your humidor. Nothing better than checking your app to see consistent temperatures!! I see some complaints about the battery, the cost of replacing the battery every three months is nothing compared to losing or drying out your cigars.

Una vez calibrado, cumple perfectamente. Es muy práctico y el margen de error muy bajo. Lo recomiendo.

Product is discontinued since April 2021 by manufacturer, Boveda doesn't sell it on their own website anymore.I found this out after buying.The idea is great and I needed this, but unfortunately the humidity is 6 to 8% off. I found it already strange that during the calibration phase it showed 85% the whole time(24hrs) and at the last minute it changed to 72%. (yes I removed the front sticker).I have tested this against a Cigar Oasis Caliber IV which I tested in a bag of 69% and in a bag with 75% boveda packs. The Cigar Oasis was for me 100% correct.I can understand and ignored complaints about the app, because everyone has a different brand of phone. For me the app was great. Hell.. I was even checking the app more than my crypto stocks heheApparently it was to difficult to produce, but I would expect from Boveda to have a decent research budget before they bring it to the market. I forgive Boveda because they make such awesome packs. But I do not recommend this product. I uses it for temperature now and just rely on the Boveda packs, which I can highly recommend.
