"system status" display not possible for several days? #11

Closed dbloms closed 8 months ago

dbloms commented 8 months ago

If I take a value greater than 1 day as the time period, then "No data in response" is always displayed in the "system status" graph. As my inverter frequently goes into standby, I would like to see the history over several weeks. Is that possible? image

The values are aggregated for everything longer than 24 hours using retention policies and continuous queries (see https://github.com/michbeck100/pv-monitoring/blob/main/influxdb/influxdb-init.iql). For strings it's not possible to aggregate the values with functions like mean or max. And it's not an option to keep the data forever in the original resolution of 10 seconds, that would be too much data.

If you have a solution for this, please reopen this issue.
