If you are looking for an advanced wireless hygrometer system that allows you to view the humidity and temperature of your humidors from anywhere in the world, the SensorPush HT1 is the best option, but it's a bit expensive.
Also the boveda has a accelerometer Which is nice for planes or driving it detects g force like if your luggage carrying your precious cigars was mistreated. I wish sensor push had that ability. Still love the sensor push.
