Cigar Oasis FAQ's

Cigar Oasis Humidifiers

Accurate sensor measures the humidity and when it is less than your desired set point, the fan is activated. It draws air from inside the humidor, runs it through the water cartridge, which humidifies the air and pushes it back into the humidor. When the humidity in the humidor reaches the desired set point, the fan stops. Typically the fan goes on every time you open the humidor and from loss of humidity to the outside ambient through to leaks in the seal of the humidor.
Cigar Oasis electronic humidifiers are active units that go on as soon as the humidity drops below the desired level and will shut off when it goes back up to that level. It requires minimum attention, just a refill of the cartridge occasionally. Whereas the passive devices require frequent attention, can't humidify in dry atmospheres, use chemicals and need replacement.
See our Humidifier Comparison page to choose the best Cigar Oasis for your humidor.
Yes. We set it at the factory, but you can adjust it from 40-90%. Recommended setting is at 70%, although, it should be at whatever you like best.
Only humidity, but it does read the temperature in Celsius and Fahrenheit.
No. Most of the time the fan is not running and when it runs it is ultra quiet (same type of fan as used in computers).
It draws less than 100 milliamps and does not create any heat in the humidor.
After 5 or 6 refills or about one time per year it is recommended that you get a new cartridge in order to have the advantage of the antifungal agent protection which gets depleted over time.
The best way to refill the cartridge is to submerge it in a bowl of distilled water for 4 minutes. When time's up, take it out and let it stand on the counter another minute. Then turn it over the sink and let any loose water drain out. Dry off the cartridge and put it back together. There must be no loose visible water in the holes.
The difference is the size humidor you will be humidifying. The Cigar Oasis EXCEL is made for desktop humidors up to 4 cu. ft. or approximately 400 cigars. The Cigar Oasis PLUS is made for larger capacity boxes over 4 cu. ft. and up to 10 cu. ft. Although physically the two models look the same from the outside, the PLUS has two additional air ports in the rear of the unit and an additional hole in the cartridge. They allow the PLUS unit to draw in more air and push out a large amount of moisture for larger spaces.
Excel & Plus take up about the space 8 cigars, 4 cigars for the Ultra 3.0.
The Cigar Oasis unit fit in virtually all humidors that store 50-1000 cigars and you do not need to drill a hole or make any other modification to your humidor. There is a ribbon cable, paper thin, that slips between the cover and the base of the humidor and connects to the Cigar Oasis unit. This ribbon cable avoids any drilling of holes in your humidor
There are a number of methods. We recommend checking out these videos below

All units are factory calibrated but you can always recalibrate to your own specifications/testing by +/- 9%
Excel & Plus: Lowest point possible with 1” minimum space for airflow throughout the humidor.

Ultra: Lid mount or upright, allow for 1” minimum space for air to flow.

Magna: Base should be as low as possible with vent flaps/fan facing the back or side of the humidor to promote airflow up, allow a minimum of 1” spacing in several shelves for air to flow. Place the remote inside the humidor approximately 9”-12” above the base for best regulation of Humidity.

Cigar Oasis for wineadors

The general principle for ideal cigar storage/aging is the 70/70 rule, 70°F and 70% RH. So long as you keep your humidor in a temperature-controlled environment there is really no benefit to a temperature-controlled humidor. In fact, trying to regulate temperature and humidity in a small space at the same time can be challenging. For this reason, we generally recommend sticking with the traditional wood, cedar-lined humidor. It is best for cigars for a number of other reasons, including: Breathability, exchange of air,full cedar interior is best for long term aging.

So, unless you’re keeping your humidor in say a vacation home or another location that isn’t temperature controlled, you’d be better off with an old-school wood humidor.
Regardless of the size of the Wineador, be it a 100 or 1000 cigar count Wineador, we always recommend The Excel 3.0.

All Cigar Oasis humidifiers are designed for the traditional and most commonly used wood humidors. These humidors both absorb and release moisture. Wineador’s, however, have an air-tight seal which can lead to a buildup and potential over-humidification.

While the Plus 3.0 may meet the Wineador’s dimension requirements/Cigar capacity, the Excel is still the best option because the Excel works with a sealed vent design as opposed to the open vented Plus. This means that the Plus can possibly over-humidify where the Excel wouldn’t.

Smart Humidor (Wi-Fi)

Smart Humidor is a subscription-based service that allows you to monitor and adjust your set point of your Cigar Oasis Humidifier(s) via app from anywhere. Smart humidor can also provide a “threshold alert”** and when there is “low water” in your cartridge/reservoir.
  • The smart humidor app is used to connect your Cigar Oasis 3.0 to your home, office, shop or other desired location Wi-Fi network.
  • Once the Oasis device is connected it transmits data once per hour to a secured server.
  • The app acts as a window, to display the hourly data readings in a vibrant graph.
  • If you feel your set point is too high/low and forgot to change it on the unit, you can change it from the app remotely.
Unlimited Devices – $3.99 p/m or $19.99 p/y
Cigar Oasis is designed first and foremost as a humidification device. The Wi-Fi Technology though integrated, is Optional. If you choose to use it a subscription will be charged.
The data is collected once per hour and dependent on the time of its first connected transmit.

Ex: if the first data point is for the 12:00p hour, and is pushed at 12:15p then the next data point should be visible for the 1:00p hour around 1:15p.
No. The Caliber Hygrometers cannot be preset because they do not add humidity to their surrounding environment. They measure the humidity in the environment, so the unit will read whatever the humidity is in its environment. Calibration may be required before use.
It is registering a humidity reading below 20% RH

Cigar Oasis Ultra, Excel, & Plus Humidifiers

There are only a few things that cause this problem. Most often, this is a water issue.

If there is any loose water in the cartridge, the water blocks the air flow and the unit thinks it's empty. It cannot draw the moisture from the cartridge and into your humidor. That would cause the low water alert and the unit to constantly run. If this is the case, please refill the cartridge according to the instructions here.

If your humidor is new or hasn’t been used for a while, it may need to be seasoned. If the wood is dry, the unit runs and the moisture is going into the wood. You may use the Cigar Oasis to season the humidor, but to season it faster you should also wipe down the wood in the humidor with distilled water.

If all of the above don't fit, then the only other reason this symptom happens is if there is a poor seal or leak somewhere in the humidor. A simple test to help determine if a leak is present, would be to place the humidifier in a sealed bin/container. If the behavior in question stops and the device performs as expected the humidor itself may be cause of issue. If that's the case you need to address that problem before you can go any further.
The Cigar Oasis is factory calibrated to 70%. Some environments and preferences may require slight adjustment. A calibration can be adjusted +/- 9 %

1. Press the circle & Up arrow at the same time. The Temperature will change to U 0.
2. Use the up or down arrow to make desired adjustment.
3. Once adjusted to desired offset, repeat step 1 to lock the adjustment. Reading will display from U X (x representing the +/- adjustment) to temperature. Allowing the screen to revert to temperature on its own will not lock the adjustment.

* You can confirm the locked adjustment by performing step 1. If the temperature changes to reflect U - X (x representing the +/- adjustment) then you’re all set. The adjustment was locked correctly and you can blow temperature to revert on its own at this point.

Cigar Oasis Magna

The proper placement for the MAGNA in the cabinet is key in ensuring that the desired humidity can be reached throughout the entire cabinet.
  1. Position the MAGNA so that the”flaps” (where the humidity is released from) are facing a direction which promotes the most wherever the most open space for air flow.
  2. There should be at least two inces of open space for the air travel throughout the humidor. Be careful not to place cigar boxes flush against the inner walls as that can block the airflow.
  3. The unit should ideally be placed in the lower portion or just under middle of the cabinet.
  4. The best remote placement varies on humidor size and style. While it has an 18” stretch, you do not want to place on top or very close to the base. Alternatively do not place the remote at the full length of the cable.
MAGNA 2.0: The Auxiliary Fans are designed to only turn on once the unit reaches the desired set point.

MAGNA 3.0: The (optional) Auxiliary Fans are designed to stay on at all times.
The sensor is located on the remote, so if the remote is positioned a few shelves higher the base a lower reading would be normal until there has been sufficient time of the cabinet being closed for the humidity to travel upward. However, if the remote is on a lower shelf and or the humidity does not rise to Set Point even after a few hours of the humidor being completely closed, please check the following:
  1. The water base has water, but is not more than 3/4 full. There should be about 1 inch of space between the fill level and vents so the humidity can properly escape.
  2. The unit is properly positioned so the vents are facing an area where the air can travel straight up uninterrupted by any boxes or obstacles. The seal on the humidor is tight and Auxiliary Fans may be necessary.

‘Wineador’ (Temperature controlled Humidors)

Unlike the traditional wood humidor which both absorbs and releases moisture, the Wineador has a very tight seal and the partial cedar interior absorbs very little of the humidity.

In addition, cold air can interact and prevent proper humidification. This is especially the case for smaller and tighter spaces. At times the humidity may go too high or too low. Below are some common troubleshooting questions and solutions.
The cooling may be negatively interacting with the humidifier. Here are a few solutions:
  1. Ensure the oasis is at the furthest point possible from the cooling element within the humidor
  2. Adjust the temperature to 68 or 70 degrees this can help the humidifier reach the desired humidity. In some instances, if the temperature cannot be raised or if the above suggestions have still not worked, we recommend turning off the temperature control or unplugging (Unless of course it is located in a non-temperature-controlled environment that requires the cooling)
For the various reasons mentioned above, the Wineador can at times have an excess of humidity trapped inside. In addition, over-humidification can be caused by the humidifier working overtime to combat the cooler air being produced by the humidor. Here are a few solutions:
  1. Release the excess humidity by opening the door of the humidor until the reading is below the setpoint. This technique is referred to as “burping”
  2. Adjust the temperature to 68 or 70 degrees this can help the humidifier reach the desired humidity. In some instances, if the temperature cannot be raised or if the above suggestions have still not worked, we recommend turning off the temperature control or unplugging (Unless of course it is located in a non-temperature-controlled environment that requires the cooling)
Example: My calibrated digital hygrometer is reading 67% RH while the Cigar Oasis reads 75%

The Cigar Oasis sensor is designed to remain constantly active and release humidity at the moment it detects even 1% dip in humidity. In addition, the Cigar Oasis sensor reads is in real-time while most hygrometers can take minutes if not more to adjust. And again, with the tight seal, the humidity can make even a short burst of humidity settle on the Oasis sensor and take some time before it can adjust.

Here are a few solutions:
  1. Make a habit of routinely “Burping” the Wineador as explained above
  2. Re-calibrate the Cigar Oasis +/- up to 9% to balance out this difference

Smart Humidor (Wi-Fi)

  1. The Cigar Oasis 3.0 unit, links to your phone utilizing a Wi-Fi connection for a self-generated Access Point.
  2. Easy to follow prompts in our app will ask you to choose your Oasis product and guide you to enabling the Wi-Fi on the unit.
A “manual setup” page asks you to enter the following:
  • Wi-Fi network name (for the 2.4ghz Network, exactly as it would appear when joining a computer or other device *note, spaces in the network name have prevented successful connections in the past. Do not Omit spaces if they exist. Suggested work around is the creation of a 2.4ghz guest network without spaces in the name.)
  • Password security type (WPA2, WPA or WEP only. Mixed securities are not compatible at this time. If you choose the wrong security type, open or other than the 3 shown, the Oasis will be unable to connect)
  • Password for wifi network is Required, Open network security will prevent connection (Password is case sensitive)
(**The oasis unit can only connect to a 2.4 ghz frequency. Display of frequencies may vary by provider, router equipment or Mesh Network setup. You may need to contact your provider to determine how to seperate the bands or turn off the 5ghs band on the router until after you’ve connected.**)

Please note:

  1. All Wi-Fi routers have a 2.4 GHz band(often identified with “2.4”,”2”or “24g” at the end of the name. Example: “myHomeNetwork2.4”.
  2. Newer routers are often dual-band router, with 2.4 GHz and 5 GHz bands. “Mesh Networks” have options to make both visible for purposes of connecting. Steps to enable or disable vary by equipment.

What is the difference between 5ghz & 2.4ghz Wi-Fi ?

  1. 2.4 GHz offers stability and better range for small data transmissions, such as humidity and temperature from your Cigar Oasis 3.0. (used for most Smart accessories)
  2. The 5GHz band, which is the newer of the two, has the ability to prioritize heavy network traffic maximize network performance. Examples include, Online Gaming, HD Streaming, Large file downloads, and Remote access for work from home
  1. If Wi-Fi credentials were entered correctly and transmitted successfully a Solid Wi-Fi symbol will appear on the Oasis Screen. Your app may reflect you have a device in “Pending Validation”. This is expected. The device after a short period of time may also power off and on, or flash a blank screen for a short period. This signifies an update (if eligible) is installing after a connection has been made. Please do not unplug during this behavior. Once the device is validated (15-30 minutes, on occasion up to 24 hours)
  2. If the credentials are incorrect, a “Warning/Alert” (Triangle with !) Will flash. You will have to clear the oasis unit and attempt the connection process again.
    ** The units can only take what is provided and attempt to apply it for a connection, if it applies and cannot connect something was provided incorrectly or mis-entered. The Oasis will require "Clearing credentials" steps before proceeding**

”Pending Validation” is an expected and automated part of the wifi setup process. In many cases it will take 15-30 minutes, in some cases it can extend to 24 hours

  1. The app collects information such as account email, device Mac ID and Device Name. It creates an Identity and passes it to the server.
  2. The Cigar Oasis, after receiving correct wifi information, sends a call to the server to ask for the identity.
  3. when the app profile ID & device ID link on the server the validation its completed.(On occasion if device is eligible for update, this will complete after the update)

What if I have been in pending Validation over 24 hours ?

the app may have passed the profile, but the device its blocked by a network setting or has been provided incorrect information for the wifi network. Please review troubleshooting page for clearing credentials and how to connect. If further assistance is required complete a, support form

  1. Power cycle the device by unplugging the power cable for 10 seconds and plug back in. Before the readings appear, a 6 digit code will populate, this is the Operating software of your Oasis.
  2. When display readings appear, press and hold the “circle” button until the “F/C” next to the temperature begins flashing
  3. Lift your finger and press the circle button 1x, a Wi-Fi icon will flash
  4. Press the “down” arrow 1x, a warning icon will flash with the Wi-Fi icon
  5. With both icons flashing, press and hold the circle button until the icons stop flashing.
  6. Unplug the device immediately after the icons stop flashing, wait 10 seconds, plug power cable back in.
** if your oasis software is on v.263 or later, disregard step “6”, instead continue to hold circle button from step 5, the unit will power off on its own completing the clearing credentials function**
When you power cycle the device up (unplug for 10 seconds, plug back in, a 6-digit number will appear on startup. The last 3 large numbers identify the device software version.

  • Current factory release Ultra, Excel, Plus (276/272) - Latest Available Update v.276
  • Current Factory release Magna (476/472) - Latest Available Update v.476

  • **Note, All connected devices if eligible for an update will automatically receive an OTA (over the air) update. Your device screen may flicker off and on or Flash display readings for a short period indicating download / installation. Do Not Unplug device**

    When you open your app, on the title screen, the app version will appear under “Cigar Oasis”. Ex: iOS displays 1.2.3, Android displays
      ** As of 03/20/2022 current app versions are 3.1.0 iOS & Android **
    1. The Wi-Fi symbol can occasionally go on or off even while remaining connected.
    2. In general, a flashing warning sign (triangle with an “!” in it) will present when a connection is lost.
      ** if your oasis software is on v.271 or later, there is a function built in to reduce heat caused by the components resulting in false ‘High temperature readings”. The function powercycles the wifi component hourly, upon successful completion of a data log. This function also acts as a failsafe if a connection is temporarily lost.

      If the app shows your device hasn’t complete any logs for 6+ hours, please contact us for further assistance.
    1. Primary cause is any conditions that are not exact to the initial connection of the device can cause a drop off.
    2. The latest version of our software has an intentional Wi-Fi shut off to resolve a false temperature reading. It has a built-in failsafe to continue attempting to reconnect.
    3. Moving the device from one Wi-Fi location to another (from home to outside office).
    4. Distance from router, signal interference (common with older routers)
    5. A change to network settings, (renaming, security update, or new router)
    6. A change in service provider.
