Another neat feature in Ruuvi Station is the History view, which allows you to explore the recorded sensor values in graphical form. To access this feature, select History view from the three-dot menu (dashboard) or tap on the graphs icon (full image view) on Sensor Card.
The history view page shows individual XY-axis grids for each of the measurements. You will be able to explore various graphs such as temperature, air humidity and air pressure, depending on which measurement components are available on your Ruuvi Sensor.
The Y-axis shows the recorded range for each, while the X-axis shows the time of recording according to the local time zone settings on your mobile device.
Important notice: not all our Ruuvi Sensors are equipped with the same measurement components. For example, if you have a RuuviTag Pro 2-in-1 that measures only movements and temperature, humidity and air pressure readings will remain empty and are hidden from view. Read more about the different sensors and their components here.
Recording Data When Ruuvi Station Is Running In Background (Bluetooth)
When you visit the History view page for the first time on an iOS device you will be shown a popup, which will suggest that you keep the connection open to the Ruuvi sensor when the app is running in the background. This is highly recommended since background scanning enables Ruuvi Station to record local sensor values using Bluetooth connection when the app is minimised or your mobile device screen is turned off or locked. On iOS this also enables you to use local sensor alerts over Bluetooth. iOS Bluetooth pairing works as long as the Bluetooth connection is active to this specific mobile device.
On Android devices no special user action is required to enable local sensor alerts over Bluetooth. Android devices are also able to listen to Ruuvi sensor broadcasts and record data to the Ruuvi Station app by default when the app is minimised and running in background.
Important notice: depending on the model of your mobile device, recording sensor data in the background can be more reliable when the phone is connected to a charger and when any form of power management settings are disabled for the Ruuvi Station app in the operating system settings (Android).
If your sensor is out of the Bluetooth signal range for a prolonged period of time, you can also import the latest data from the sensor’s internal storage, which can record 10 days of data at a time. Press the Sync button to download the latest 10 days sensor data to your phone over Bluetooth.
To access RuuviTag features such as local history logging and alerts on iOS, Ruuvi firmware version 3 is required. Update your Ruuvi sensor firmware in Ruuvi Station app on Sensor Settings page.
Scan Interval In Ruuvi Station
Ruuvi Station scans and updates sensor values in the app according to set intervals. History view is able to show the measurement history for a maximum of 10 days on the Ruuvi Station mobile app. A longer measurement history is available on the Ruuvi Station Web app depending on your subscription plan (requires Ruuvi Cloud Basic or higher).
Ruuvi Station records sensor values in four different ways:
- Local Bluetooth sensor values are updated once per 2.5 seconds, when Ruuvi Station is in the foreground, or
- Local Bluetooth sensor values are recorded according to Background scanning interval settings, when Ruuvi Station is in the background, or
- Local Bluetooth sensor values are imported by manually synchronising sensor data over Bluetooth, or
- Sensor values are synchronised from Ruuvi Cloud (requires Ruuvi Gateway router)
To change background scanning intervals (Bluetooth), please go to App Settings -> Background Scanning. You can also enable or disable background scanning here.
This setting doesn’t affect the interval used to synchronise sensor data and settings to your Ruuvi Station app from the Ruuvi cloud. Cloud synchronisation intervals are defined in your subscription plan (requires Ruuvi Gateway router) and cannot be adjusted in the app.
Important notice: depending on the model of your mobile device, background scanning can be more reliable when the phone is connected to a charger and when any form of power management settings are disabled for the Ruuvi Station app in the operating system settings (Android).
Exploring recorded values in History view
Explore each individual grid by using pinch-to-zoom gestures and/or scroll and move through the grid from left to right or up and down by simply positioning your finger on the place where you want to start scrolling from. You can also use double tap to zoom to any XY-axis location on the grid.
Single tap on a recorded datapoint in the graph will show detailed information regarding that specific datapoint and shows the corresponding datapoint in the other visible graphs.
You can furthermore choose a specific number of days of historical data to be shown in history view by choosing a number of days from the dropdown menu.
