I know a few things have been asked about the history add-on, but I just want to clarify. We currently use the free Developer service, and we make some history requests. We're starting to exceed the 500 requests per day limit, and are looking at upgrading to the Drizzle plan, but it costs a lot more to get the history add-on with this. If we don't get the history add-on, does this mean we won't be able to make any history requests at all? Note that we need history data for yesterday, last week and last year.
