Set Up Your Smart Humidifier Bundle for Whole-Home Comfort

Quick answer

Set up your DREO smart humidifier bundle by placing each unit in the right room, connecting both to the DREO app, and adjusting humidity targets so they work together without over-humidifying.

Steps to set up your smart humidifier bundle

1. Unpack and place each humidifier: Place the larger unit (e.g., 735S) in your main living area, at least 12 inches from walls and furniture. Place the smaller unit (e.g., 524S) in a bedroom or home office, away from electronics and direct airflow on sleeping areas. Common mistake: placing both units in the same room or too close to each other, which causes humidity overlap and wasted water.
2. Connect both humidifiers to the DREO app: Install the DREO Home app, create an account, and follow the in-app pairing instructions for each humidifier. Make sure your phone is on the same 2.4 GHz Wi‑Fi network during setup. Once paired, name each unit by its room (e.g., "Living Room" and "Bedroom") to avoid confusion. Check that both units appear online in the app before moving to the next step.
3. Set separate humidity targets per room: In the app, set the living area unit to a target of 45–50% RH (relative humidity) and the bedroom unit to 40–45% RH. This prevents the bedroom from feeling clammy while still keeping the whole home comfortable. Enable the auto mode so each unit adjusts its mist output based on its own sensor. Common mistake: setting both units to the same high target (e.g., 55%) — the bedroom will likely overshoot, causing condensation on windows.
4. Schedule runtime to match your daily routine: Use the app's scheduling feature to run the living area unit during daytime hours and the bedroom unit for a few hours before bedtime. This saves water and energy when rooms are unoccupied. For example, set the 735S to run 8 AM–10 PM and the 524S to run 8 PM–6 AM. Check that schedules don't overlap heavily — if both run at the same time, you may still over-humidify shared zones like hallways.
5. Monitor and adjust after the first week: After one week, check the app's humidity logs for each room. If a room consistently stays above 55% RH, lower its target by 5%. If it stays below 35% RH, raise the target or increase the schedule duration. Fine-tuning is normal and ensures long-term comfort. Empty the water tanks and clean the filters monthly to keep sensors accurate and prevent mold.
