Frequently Asked Questions - RadonEye

1. Can RadonEye connect two phones at the same time?
A) Because RadonEye uses Bluetooth, it can connect one phone at a time to view data. To connect to RadonEye from another phone, you need to close the RadonEye app on the previously connected phone.

2. Operating temperature range of RadonEye & Pro
A) The operating temperature range of RadonEye is 32°F ~ 104°F / Relative Humidity < 80%. 

3. RadonEye "SAVE AS" button is not displayed
A)  If you cannot see the button below the graph, check your display settings (normal) in your phone settings.

4. Why do I need to turn on location services to pair with a Bluetooth device?
A) RadonEye has no cloud or server services and does not have access to customer location information. To access devices via Bluetooth from an Android phone, it requires permission to access the location. Recent updates to the Google Android API affecting Bluetooth LE technology require location permissions to be granted in order to use the app. The app doesn't need location permission on iOS to use BLE scanning.

5. Is there a timestamp on RadonEye?
A) The RadonEye does not have an internal clock or timestamp, so it does not display data according to a calendar or time interval. Our customers usually export data to an Excel file to track time and date. RadonEye records data by hour, so you can easily track time from the last data.

6. RadonEye data storage
A) The saved data files on an Android is the RadonFTLab folder. Head to Settings > Storage > Other and you’ll have a full list of all the files and folders on your internal storage. (If you’d prefer this file manager to be more easily accessible, the File Manager app will add it as an icon to your home screen.)

7. Follow up actions to determine if your device is defective
A) To verify if the device is defective, please perform a one- to two-hour measurement outdoors (screen porch, patio). Avoid deployment in direct sunlight or when it's windy, rainy or stormy. Keep it at least 20 inches above the floor or ground and do not place it on a masonry surface. If the measured radon levels are over 1.2 pCi/L, or you have further questions, please let us know. 

8. iPhone App does not support iOS versions older than iOS 13
A)  Currently, the RadonEye iPhone app does not support iOS versions older than iOS 13. iOS 13 introduced significant changes. Please upgrade your iPhone to iOS 13 to use the RadonEye app.

9. OLED Display Info
The status of the device is ready to save data after powering on the device. (It takes 1 hour after power on)
STS: NORMAL The status of the device is normal to save data.
M:1.02(DAY) Average radon level of the first 24 hours after powering on the device.
L:1.04(MONTH) Average radon level of 30 days after powering on the device, can be displayed after 30 days.
T: 5d 02: 26: 25 Total measurement time, 5 days 2 hours, 26 minutes and 25 second
ERR Error of the device OVER When radon reading over the measurable range
C:#/# C: alpha count of the current 10 minutes / alpha count of 10 minutes ago i.e. C:2/3 → 2 alpha counts of the current 10 minutes and 3 alpha counts of 10 minutes ago. This is how the radon is calculated in radon units by measuring the count that occurs when the radon collapses.The larger the count, the higher the radon value.

10. What is the expected service life of the RadonEye?
A) RadonEye is expected to have a service life of 5 years, but this depends on usage conditions, wear and tear, etc.

11. Why is the word 'OVER' being displayed on my device’s screen?
A) When the actual measurement result goes above the RadonEye RD200 measurement range, the word ‘OVER’ is displayed on the device’s OLED screen. Measurement range is from 0.2—99.9 pCi/l.

12. How to save data to your phone as a text file
A) Follow the steps below to save the data on your smartphone:
● If you tap LOGO in the bottom of the display, you should see the graph mode
● Tap on the data load. The measured data, which is saved every hour, will be displayed as a graph
● If you want to save this data on your smartphone, you should see a "save as" button
● The saved data files on an Android is RadonFTLab folder
● For iPhone users, please use iTunes
● The saved file format is .txt, which can be opened and saved in Excel If you still don't see the "save as" button, please check your phone settings and try reducing the size of the font or display. 

13. How do I update my RadonEye’s firmware?
A) When a firmware update is released by Ecosense, you will receive a pop-up alert for upgrading your device’s firmware upon connecting to it via Bluetooth.

14. Is there a way to produce a radon report with the RadonEye?
A) RadonEye does not support report generation. The data is stored on RadonEye and can be downloaded using the app. Click the “save as” button to save the data as a .txt file on your smartphone. 

15. How can I force the device to reset?
A) The RadonEye does not have a dedicated reset button on the device. If you need to reset the device, use the app and go to device Settings → Reset Data.

16. I cannot connect the device with my phone.
a. Please check your iOS version, the RadonEye supports iOS 13 or later.
b. Check your Android version, the RadonEye supports Android 5.0 or later.
c. If you cannot find the serial number in the device list,
- Check the OLED display if you can see the bluetooth icon.
- Check if the device is connected to another phone, the RadonEye connects only one phone at a time.
- Power off the device and power it on again.
d. If you can find the device but cannot connect from the app,
- Go to settings on your phone and turn off the bluetooth and turn it on again. 

17. What is the differences between RadonEye and EcoQube
A) The EcoQube and RadonEye utilize the same ion chamber technology. Besides Wi-Fi vs Bluetooth, EcoQube has a much more robust software app.

18. Sensitivity - 30 cph/pCi/L
A) Sensitivity (sometimes referred to as “Counting efficiency”) is 30 cph (Count Per Hour) per 1 pCi/L: please note that the sensitivity and # of radon-data readings are different.

According to the ANSI-AARST Performance Specifications for Instrumentation Systems Designed to Measure Radon Gas in Air the minimum compliant detector efficiency (sensitivity) for continuous monitors is 2 counts/hour per pCi/L.
Ecosense devices are 15 times more sensitive than the minimum standard, able to detect an average 30 radon disintegration counts per hour per 1 pCi/L. This means we have superior confidence in each hourly reading displayed.

The hourly radon concentrations are calculated based on the number of detected alphas produced by radon decay. Radon levels on the display are stored hourly, showing an hourly moving average every 10 minutes.

19. Information of radon readings
A) Information on the DATA tab in the app:
Max value: Highest radon reading from the saved data in the device
Average value: Average of saved data in the device
Min value: Lowest radon reading from the saved data in the device

Information on the Radon tab in the app(Same information with OLED display):
Peak value: Highest radon reading after device is turned on, reset when device is turned off and then on
1-day average: Daily radon level average - updates daily (every 24 hours) after device power on, reset when device is turned off and then on.
30-day average: Monthly radon level average - updates monthly (every 30 days) after device power on, reset when device is turned off and then on.

20. I cannot save the data from the device, what should I do?
A) If you cannot download and save the data from the device, please confirm your RadonEye's firmware version and which phone you are using. In RadonEye's latest firmware (v3.0.2), data download is only supported on iPhone 7 and above. Please try to use a different phone or tablet to download saved data from the device. 

21. How to change the measurement unit?
A) Please navigate to the app's settings by tapping the gear symbol located in the upper right corner. From the menu, choose 'unit settings' to switch between pCi/L and Bq/m3.
