Thanks Gary. For my particular situation, I might ask the author (which is myself, haha) of the weewx extension that is getting the inverter data from the REST interface, if he could implement in a way so that it is not backfilled in the usual way. Maybe an approach could be to only retrieve single values if the timestamp for the requested value is not older than x-times an interval and let it check for gaps afterwards. A call for all the values in the last 24 hours in a 5-min interval only take another second or so longer than it takes for a single reading. With this approach I have to take care of getting things right with the corresponding archive_day_-table.
Or I could implement a cache which holds all the values since the latest good record up until now and return the cached value, if cached, if not, it asks for all values since the newest good record, and caches it. Should work with some kind of static key-value-pairs variable. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
