Hi - I'm writing the binding for to support Flume devices for openhab. Given openhab has its own persistence service, I'd like to query a cumulative number of gallons used over time. I have a few questions:

• Is there any performance issues that Flume would be concerned with in having a long window range with a "since_datetime" being very early? Or, should I only do that query infrequently (like at midnight every day) and do a more frequent query to get the day usage and add that do the cumulative usage since midnight?
• In the first 2 queries below, the result is always the same even though the until_datetime is different. Any idea why?
• Lastly, is the rate limit per submission of a set of queries, or based on the number of queries (for instance, in the below there would be 4).

Thanks

Jeff
