Different retention times with Recorder?

Configuration
1

Hi,
I’ve seen people asking this question in 2019, 2020 and 2021, but I hope things have progressed since then.

I’d like to keep different retention times for different entities, for example:

  • some entities have retention time of 1 day
  • some (limited number) entities have retention time of 6 months
  • the rest should keep the default of 10 days.

Is it possible to do this with the recorder?

Thanks

No.

You can vote for this here: Recorder Retention Period By Entity

Thanks – will send the vote. :frowning: Unfortunately, sometimes it makes sense to keep some data much longer than others in order to analyze performance of systems (I talk about controlling central heating, etc).

Sure.
Most people needing detailed analysis use InfluxDB + Grafana for this.
Most HA users are happy with long-term statistics (aggregated data that never expires), nowadays.

The long-term statistics is also a challenge, e.g. the apexcharts do not display this long term data. It would actually work for me if I could simply integrate it into the existing UI. Any ideas how to do it?

I’m pretty sure they do as I triggered their addition :wink:

Unfortunately, if I add the ‘statistics’ section, there is nothing displayed and the current value of the series shows as N/A (code and screenshots before and after below)

type: custom:apexcharts-card
graph_span: 10d
hours_12: false
yaxis:
  - min: 0
    max: ~1800.0
    decimals: 0
    apex_config:
      tickAmount: 9

Then maybe your sensor does not meet the requirements for long-term statistics to be generated for it.

See:

It does have the long term statistics if I go deeper into the HA native graphs…

Maybe try

    statistics:
      type: mean
      period: hour

works for me

Thanks, but just tried it → same result…

Can you post the yaml config to see if you are doing something else differently?

Thanks … at first glance I see no (impacting) difference but let me go in detail through.

Ok, @koying, you were right way up in one of the the first posts. The state class of the entity was set to “total” instead of “measurement”. If the device class is “volume” then the state class cannot be set to “measurement” (it must be “total” or “total increasing”).

Once I removed the device class value (I simply left it empty), I set the state class to “measurement” and now the statistics in apexcharts works…

Oh, well… Why the device class “volume” cannot be of state class “measurement” I have not idea. The unit is still in litres so it shows properly and it seems to work now.

Thanks for your help.
