How to Program Smart Dehumidifiers for Automated Moisture Management

Extra humidity in your home leads to mold growth, structural damage, and bad air quality. A smart dehumidifier prevents all of that automatically. 

Program it correctly, and it only runs when needed to reach your desired humidity level every day while saving energy. This guide covers how to automate humidity control from beginning to end.

Why You Should Automate 

Manually controlling a dehumidifier is a waste of time. You forget to turn it on when you need it or leave it running way too long after the air is dry. Either scenario wastes energy or shortens the appliance’s lifespan.

With automation, your dehumidifier responds to actual humidity levels in your home. It turns on when needed to lower moisture and automatically shuts off once the air is back to your desired humidity level. You don’t have to think about it. 

The Environmental Protection Agency (EPA) recommends running your indoor humidity levels between 30% and 50%. More than 60% is ideal for mold growth. Below 30% and your air is too dry. Itchy skin and sinus irritation are common at low humidity levels. Automation helps maintain that ideal range. 

Equipment Needed 

Ensure you have the proper equipment before getting started. Every setup varies slightly, but you will need:

• Smart dehumidifier connected to Wi-Fi OR standalone dehumidifier plugged into smart plug
• Separate humidity sensor (optional but useful if monitoring a large room)
• Smartphone app compatible with your devices 
• Wi-Fi router connected to 2.4 GHz (not 5 GHz)

Step 1 – Connect to Your App 

The first step is downloading the app that controls your smart dehumidifier. Many smart dehumidifiers are compatible with Android phones and iPhones.

Launch the app on your phone and create an account if you do not have one already. Once that is complete: 

• Hold the UP and DOWN buttons simultaneously for 3-5 seconds until you hear a beep. On most models, this puts your dehumidifier into pairing mode. You will know it’s working when the Wi-Fi button starts flashing.
• Open your smart dehumidifier’s app and look for an option that says, “Add Device.”
• Pick your home’s Wi-Fi network from the list. Connect to the 2.4GHz network, not 5GHz. 
• Allow the app to complete its setup. You should see a confirmation that the device connected.

If it doesn’t connect, unplug your dehumidifier and try again. Also, keep your phone close to your wireless router while pairing. Consider purchasing a Wi-Fi extender if you plan to use this device in your basement or another room with spotty Wi-Fi. Smart homes rely on this connection. 

Step 2 – Select Your Humidity Preference 

Once you pair your device, set your desired humidity level. This is the ideal room humidity percentage your system will maintain.

EPA guidelines say between 45% and 50% is ideal for most homes. Basements hold more moisture than other rooms, so keep it around 45%. Set bedrooms and living areas a little lower or higher at 40-55% for best comfort.

Look for a setting in your app that says, “Humidity Target,” “Set Point,” or “Dryness Level”. Input your desired humidity level and save. Your system will now work towards maintaining this level automatically.

The Heater Shop from the UK noted that advanced dehumidifiers like the AC Infinity Hydrone even have artificial intelligence (AI) mode. It studies humidity trends over time and automatically adjusts its settings to prevent humidity from spiking. AI mode is beneficial if your space has rapidly changing moisture levels.

Step 3 – Adjust Your Humidity Triggers 

We mentioned triggers help determine when your device should turn itself on and off. Most apps allow you to set upper and lower thresholds.

Set your device to activate when humidity exceeds 60% but turn off once it hits 45%. That gives your dehumidifier a range of 15 points to maintain before turning off. If the points are too close together, your dehumidifier turns on and off too frequently. It wastes energy and stresses the fan. 

This range between turning on and off is called hysteresis. Ideal hysteresis range is between 5-10%. Too low, and your device turns on/off too frequently. Too high and the humidity will swing more than you want.

Home Assistant users can skip app configuration and input these details yourself. Using your home’s humidity sensor data, you can configure a component called “generic hygrostat.” It allows you to set your own humidity high and low triggers.

Step 4 – Create a Running Schedule 

Triggers cover sudden rises in humidity. Scheduling your device for optimal run times saves you even more money. Your system can’t run when it’s not allowed to, even if the humidity is too high.

Your dehumidifier probably doesn’t need to run at night. Unless you live in a very humid climate, humidity increases when you shower, cook, or during the hotter afternoon hours. Set your system to run anytime during these periods and stay off when you don’t need it.

Locate “Schedule” or “Timer” in your app. Set available run times in 30-minute or 1-hour increments. We recommend leaving it available from morning to night. For example, from 7 AM – 10 PM. You can adjust it as needed later if your device runs too frequently or not enough. Outside of those times, your device will stay off no matter how humid it gets.

Step 5 – Configure Smart Home Integrations 

Both Alexa and Google Home allow you to create routines. These are customized commands that control smart devices using one command. You can tell Alexa to “turn on dehumidifier” or include it in your goodnight routine that runs when you tell your smart home you’re going to bed.

IFTTT (“If This Then That”) is another excellent service to look into. If you connect your dehumidifier using IFTTT, you can tie its actions to other apps you use. Set your dehumidifier to turn on if your weather app detects high humidity levels in your area.

Step 6 – Observe and Refine 

Wait one week then analyze results. Review your app’s history logs to see when and how often your device ran. If it’s too much, increase your trigger point. If humidity is still getting too high, lower your humidity target level.

You can usually view usage logs, energy consumption, and filter change reminders through your app as well. Review these monthly to ensure everything is functioning correctly.

If your device offers the ability, turn on notifications for when the water tank becomes full. The dehumidifier automatically powers off if it fills. When you are away from home, that could cause humidity to spike until you return and notice. Get a notification when your tank is full and empty it right away.

Automatic Humidity Control Done Right 

Setting up your smart dehumidifier should not take more than 30 minutes. After you connect it to your smartphone and enter your preferred humidity levels, automating the rest is easy. Add triggers and a schedule before connecting it to your smart home system. Your house stays dry, your humidity stays consistent, and you save money all year long.

Dehumidifier FAQs 

What is the ideal home humidity level I should keep?

We recommend 40–50% relative humidity. Lower humidity will eliminate mold & dust mites. Higher humidity keeps your home comfortable while limiting other allergens like pollen.

Will a dehumidifier help with my allergies? 

Absolutely. Dehumidifiers keep humidity levels low to prevent dust mites and decrease mold spores which are known to trigger asthma and allergy symptoms. Try pairing your dehumidifier with an air purifier with a HEPA filter!

Do I need a smart dehumidifier? 

A regular model will suffice for small spaces with moderate humidity. Smart dehumidifiers can be programmed for hands-off control and are best used for larger areas, whole-home systems, or rooms with extreme changes in humidity. Smart dehumidifiers also conserve energy by limiting run time.

How do I know what size dehumidifier to buy?

It depends on how large the space is and how much humidity you wish to remove.

Humidity is HIGH: 

• Small rooms – 30-pint dehumidifier 
• Large bedrooms or basement – 50-pint dehumidifier or higher
• Whole-home or commercial use – 70 – 200+ pints 

Humidity is Moderate: 

• Stick with a 30-pint dehumidifier. 

Can I leave my dehumidifier on all day?

If your dehumidifier has a built-in humidistat or can be programmed smartly, then you can! A humidistat will allow the dehumidifier to sense when it reaches your desired humidity level and shut off to prevent your home from drying out too much. Running your unit continuously will also increase energy costs.

Where should I place my dehumidifier? 

Dehumidifiers should always be at least 12″ from walls/furniture. You can place your dehumidifier in the center of a damp room or close to the area that is most affected by humidity. If you have a large room with multiple areas being affected by humidity, we suggest purchasing more than one dehumidifier or placing a fan in the room to allow for better circulation.

Is it necessary to clean my dehumidifier? 

Yes. Regularly empty the water tank or drain if necessary. Most units have disposable filters, so clean those every 2 weeks. Lastly, you’ll want to wipe down the coils once a year to prevent mold or bacteria from growing inside your dehumidifier.

Should I run my dehumidifier year-round? 

Yes! Dehumidifiers are great for helping you remove excess moisture in the hot & humid months. But did you know that many LGR or desiccant dehumidifiers can run during cooler months as well?
