Boveda - Butler: Smart Hygrometer

The Boveda Butler (formerly Boveda Smart Sensor) is the first smart humidity management system for your humidor. It monitors your humidor and its precious contents, and sends you alerts about humidity and temperature right to your phone—no matter where you are. With the Boveda One-Step-Calibration Kit, you can easily calibrate the Boveda Butler for truly accurate readings.


• Continuously monitors humidity and temperature levels inside your humidor and allows you to access those readings from anywhere.

• Detects changes in real time as they happen and alerts you if readings are outside your customised humidity and temperature ranges.

• Keeps a history of hourly, daily, and monthly humidor readings and can use this data to adjust for seasonal changes.

• Alerts you if your humidor has been opened, moved, or dropped.

• Lets you know if you need to buy a new Boveda humidity pack right from your app.

• Professional-grade calibration for truly accurate readings.

• Allows remote monitoring of your humidor so you can access the data from anywhere in the world.

• Eliminates the need for a separate hygrometer and thermometer.


You can just place the Boveda Butler inside your humidor on top of your cigars, or you can put it on top of your humidor’s lid. It communicates with your iOS 8.0+ or Android 5.0+ mobile device via Bluetooth, so you can access the conditions in your humidor at all times with the free Boveda app.


The Boveda Butler is the world’s only humidor monitor that features the Boveda One-Step Calibration Kit. This way, the Boveda Butler can ensure that your humidor RH readings are truly accurate. The Boveda Butler uses the same type of professional “salt test” calibration that is used by professionals in labs to determine the accuracy of a hygrometer. In just 24 hours, you can perfectly calibrate your Boveda Butler’s digital hygrometer.


Want to check on your valuables while not at home? You can extend the reach of the Boveda Butler so you can access the real-time data from anywhere in the world by syncing up the Boveda Butler to a second compatible tablet or smartphone.

The Boveda Butler stores up to 10 days of data when out of Bluetooth range. If the period of no connectivity is longer than 10 days, the sensor can only download the last 10 days of data to the app when connectivity is re-established.

Before use, you must first calibrate the Boveda Butler with the Boveda One-Step Calibration Kit. After calibration, you’ll sync it to the Boveda app and can place your Boveda Butler inside your humidor.

    Accurate and simple to sure
    Come with instructions and calibration packet ( you put boveda 75% RH pack in a bag with sensor for 24h to calibrate). After calibration just put it where ever you want and track stuff on your phone =)
