Why do I have no data?
Looking at an empty summary screen? Don’t worry, there’s a few easy things to check to troubleshoot a lack of measurements.
Is your Flow warming up?
Your Flow requires a warm-up period to ensure that the gas sensors inside the device work to maximum capacity. This happens:
When your Flow is installed for the first time.
If your Flow runs out of battery and is recharged.
When your Flow has just performed a firmware update.
If the lights on the front of your Flow are flashing yellow, just wait a little while for your Flow to wake up.
Are you connected?
You can tell your Flow is connected by checking the Bluetooth icon on the companion app’s live screen. The Flow application displays three different possible Bluetooth states.
Flow is connected to the application, measurements are transferring in real time.
Flow is not connected to the application, you are not receiving real time measurements, though they are being stored in Flow’s internal memory and will download as soon as you connect to the app.
If you are having connection problems, try moving the Flow device closer to your phone. If this doesn’t make a different, check your smartphone’s settings to see if you are connected to the Flow via Bluetooth. If so, forget this association in your Bluetooth settings, then relaunch the Flow app. Follow steps in app to reconnect to your sensor.
Your phone’s Bluetooth is deactivated. Turn it on to start the data download!
Do you see a progress bar?
If this is your first connection today, you may have to wait a little while for the data synchronisation to complete. This is due to the large amount of data transferring from your Flow. If you see the progress bar appear, your data is in the process of uploading, though you may not see any measurements in the app yet.
