RuuviTag sensor data can be exported to a .csv file both in Ruuvi Station mobile application and web interface. This allows users to edit and store long time history data in data format that is compatible with Excel.
RuuviTags themselves measure once per 2.5 seconds. This measured data is broadcasted, and additionally RuuviTag stores one measurement per 5 minutes internally.
Ruuvi Gateway sends this data to Ruuvi Cloud once per minute, and the data is downsampled to once per 15 minutes after 24 hours.
So there are 4 possible data sources:
- RuuviTag broadcasts 2.5 seconds interval
- RuuviTag stores history data 5 minutes interval
- Ruuvi Cloud recent data (24 h) 1 minutes interval – Ruuvi Cloud old data 15 minutes interval
When a .csv export is done on the mobile application, all the data available to your device is included in export. This can cause different intervals in exported data.
Please notice that up to 10 days history data is available in the mobile app. In Ruuvi Station web app, you are able to store up to 2 years (Pro plan) and 3 years (Business Starter) history data (requires Ruuvi Gateway router and Ruuvi Cloud subscription).
