How much data does Sense store when disconnected

[ben]

Depending on which FAQ and which forum thread you read, the answer varies between 6 and 8 hours.
See this response from RyanAtSense from September of last year when he stated a 6 hour buffer.

At the moment, Sense records a 6 hour buffer in the event of a connection loss. That may not sound like much, but there’s quite a lot of data from that 6 hour period. Ideally, we’d store more and hopefully can in the future.
