Airthings Wave Plus setup means installing the 2 AA batteries, placing the monitor in a stable indoor location, pairing it with the Airthings app over Bluetooth, and allowing about 7 days for the sensors to settle. After that period, use the app to review radon, CO2, VOCs, humidity, temperature, and air pressure readings.

The Wave Plus is a battery-powered monitor with a radon sensor and 5 air-quality sensors. It measures six indoor air factors and gives a color-coded visual indication when you wave in front of the device.

What do you need before Airthings Wave Plus setup?

You need the Airthings 2930 Wave Plus, 2 AA batteries, a compatible smartphone, and the Airthings app. The box also includes a Quick Start Guide and Airthings Support.

Choose the room before inserting the batteries. A fixed location makes the first measurement period easier to understand because changes are less likely to come from moving the monitor between rooms.

For a second opinion on which model suits your home, compare the best Airthings radon detector options. The Wave Plus is designed for people who want radon readings alongside CO2, VOCs, humidity, temperature, and air pressure.

How do you install the Wave Plus batteries?

Install the 2 AA batteries supplied with the Wave Plus, following the battery orientation shown inside the compartment. Close the battery cover securely before placing the monitor.

The Wave Plus is battery powered, and its stated average battery life is 1.5 years. Keep the monitor accessible enough that you can replace the batteries without moving furniture or disturbing its long-term position.

The device measures 1.4 in deep and 4.75 in wide by 4.75 in high. Its round form works best on a level surface or in a location where it can remain steady and uncovered.

Is the Airthings Wave Plus Bluetooth connection required?

Bluetooth is the normal phone connection for initial setup and detailed app readings. Keep your smartphone close to the monitor while pairing, and make sure Bluetooth is enabled before opening the Airthings app.

The app provides more detail than the Wave gesture. The device itself gives a color-coded visual indication, while the app is used for detailed insights into the indoor air measurements.

If you need another device in the same system, check Airthings Wave Plus compatibility before adding it. The Wave Plus is listed as compatible with Airthings View series devices, the Airthings Hub, and Alexa.

Where should you place Airthings Wave Plus?

Place the monitor in the indoor room you want to monitor, where it can stay stable and uncovered for the settling period. Avoid locations where it may be knocked over, blocked by objects, or exposed to unusual moisture.

Choose a spot that reflects the room's normal conditions. A living area, bedroom, or lower level may each answer a different question, so decide whether your main goal is a general household baseline or a closer look at one specific area.

Do not move the unit repeatedly during the first week. The Wave Plus needs about 7 days to adjust to its new environment before the measurements provide a useful starting point.

Keep the device away from temporary conditions that could distort your comparison, such as a freshly opened window or a nearby cleaning task. Once the settling period is complete, continue using the same position when you want to compare readings over time.

How do you pair Airthings Wave Plus with the app?

Open the Airthings app, select the Wave Plus, and follow the Bluetooth pairing instructions while keeping your phone near the monitor. Allow the app to finish finding and connecting to the device before leaving the setup screen.

If the monitor does not appear, check the battery position and confirm that Bluetooth is active. Close and reopen the app if needed, then try again with the phone close to the Wave Plus.

After pairing, review the sensor names shown in the app. The Wave Plus tracks radon, CO2, VOCs, humidity, temperature, and air pressure, so you should see more than a single radon value.

The Airthings app is useful when you want detailed readings rather than only the device's color response. Use the app to check whether the monitor has connected and whether the data is updating.

What should you do during the 7-day settling period?

Leave the Wave Plus in its chosen location for about 7 days and avoid judging the home from the first short reading. The settling period gives the sensors time to adjust to the room.

Record the room and the setup date if you want a simple reference. You can then compare later measurements against the same location and know when the monitor began collecting data there.

The Wave Plus is intended for continuous, long-term measuring because radon levels can change from day to day. A single early reading should not be treated as a complete picture of the room.

If you also want a portable radon-focused monitor, the Airthings Corentium Home Radon Detector 223 uses 3 AAA batteries and shows short-term and long-term readings on its screen.

The Corentium Home measures 1 in deep by 2.7 in wide by 4.7 in high and weighs 3.52 oz. Its ABS enclosure and 3 AAA battery power suit people who want to move one monitor between rooms.

How do you read the first measurements?

Use the Airthings app to review the six sensor readings after the settling period, then look for patterns instead of reacting to one number. Radon, CO2, VOCs, humidity, temperature, and air pressure each describe a different part of the room's conditions.

The Wave Plus can show a color-coded visual indication when you wave in front of it. Use that as a quick check, then open the app when you need the detailed measurements.

High or changing readings call for context. Note whether the room was occupied, whether windows were open, and whether cooking or cleaning took place nearby, because those activities can change indoor conditions.

For a separate initial radon screening option, the First Alert Radon Gas Test Kit includes test materials and lab fees, excluding New Jersey state fees. It is listed under the EPA radon gas measurement proficiency program and is recommended for use only within the United States.

The First Alert RD1 is intended for an initial screening rather than continuous app-based monitoring. Its results are emailed within 72 hours of lab receipt, giving you a different way to check for radon.

How should you maintain the Wave Plus?

Keep the monitor uncovered, leave it in a stable location, and replace its batteries when needed. The Wave Plus has an average battery life of 1.5 years, although actual timing can vary with use and conditions.

Keep the device within its operating humidity range of less than 85 percent. Do not place it where unusual moisture could reach the monitor or where the unit may be splashed.

If you want remote or connected use, review the Airthings Hub and View series requirements before changing the system. The Airthings View Plus vs Wave Plus comparison can help if you are choosing between a Wave-style display and a broader connected monitor.

For battery planning, see the guide to Airthings Wave Plus battery life. Replace batteries before they run out if you depend on continuous measurement.

What should you do if setup fails?

Start with the simple checks: batteries, Bluetooth, app access, distance from the phone, and sensor settling time. These checks cover the most common setup interruptions without changing the monitor's location unnecessarily.

If the app cannot find the device, confirm that the batteries are facing the correct way and move the phone closer. If readings appear incomplete, give the monitor time to settle and check again after the 7-day period.

For a step-by-step fault check, use this Airthings Wave Plus troubleshooting guide. Keep the monitor in the same room while you work through the checks so you don't create a second placement change.

What is the simplest Airthings Wave Plus setup plan?

Choose one room, install the 2 AA batteries, pair the monitor over Bluetooth, and leave it in place for about 7 days. Then use the Airthings app to review the six sensor readings and continue monitoring over time.

Choose the Wave Plus if you want radon and broader indoor-air measurements in one battery-powered device. Choose the Corentium Home for a portable radon detector with on-screen short-term and long-term readings, or the First Alert kit for an initial lab-based screening.
