I now use iOS and Android Apps, and the Web site which gets updated via the Gateway.
I noticed that sync seems to work differently. Maybe it has been documented somewhere but then I must have missed it. I used to sync the RuuviTag data with the phone Apps, each sensor separately (it was a pain), but now it seems that hitting the Sync button in the App gets the data from the Web, and it updates data from all RuuviTags at once. When I tried to sync using a phone whose App had not been logged to my Ruuvi account, nothing was synced.
Also, some plots still have gaps. I thought I could have retrieved that data directly from the RuuviTag, using RuuviTag-to-App sync but such sync does not seem to exist anymore.
Could you please summarise how syncing is supposed to work with Apps, Gateway and Web? Please clarify also that if I take a sensor away from my home and Gateway, and want to measure the temperature, e.g., in my tent when camping, can I sync this data to the App or the Web?
