By local I mean that ownership has not been claimed to Ruuvi Cloud for this particular sensor and it’s been listened to via local device Bluetooth (not Ruuvi Gateway)?
For the app, we show no data in last 10 days when there’s no measurement available for that sensor. We store the latest point to local storage even if it is older than 10 days. But, sometimes that point can be removed under different conditions. I can’t exactly tell under which conditions on top of my head now as this is a complicated area which needs an investigation.
