What do you exclude from the recorder?

Hi all,

Some time ago I moved to using mySQL for the recorder in HA. Noticed my database is 1.6GB in size. That got me wondering, is there any low hanging fruit with regards to stuff I can exclude from the recorder without affecting HA?

For instance I use the time sensor and datetime, noticed every minute its writing its new time value… could I exclude that? This also got me thinking if there is any other useless stuff being written by default.

Also you should notice an improvement after updating to (the yet to be released) v0.112. It has some optimisations in how it stores states.

And GLOB filtering support :slightly_smiling_face:

so, like this?

    - sensor.*_voltage

Yes. Although technically the syntax will be this

    - sensor.*_voltage

some good hints here thanks chaps

As far as I am aware, excluding entities from recorder would not affect HA. Just that you would not be able to see the history state of that entity. I am running on a NUC, and I have influxdb running in parallel which records and stores all the sensors. As for recorder, I excluded most of the sensors that have a lot of data coming in (I have several Bruh DIY sensors), and I have set the purge_keep_days: 2 to keep only two days worth of data. If I need to see anything beyond that, I access influxdb through grafana. This way, the database size is ~700MB.

Finally! my recorder config is starting to get a bit unwieldy

It affects the reliability if using an SD card.

Yeah, One of the reasons I moved to a NUC.

@tom_l @bacco007 actually I may have been off about the timeline. The PR for glob filtering support was merged into dev about a week ago so I assumed that meant 0.112 release. But looking at the beta release notes I’m not seeing it so I think it may be 0.113. Still learning how the release schedule works, sorry about that.


As long as it’s in the pipeline, I can wait.

Just confirmed it’s in the 0.112 beta (I applied a glob filter to recorder). It is in the release notes, but it’s buried in All Changes at the bottom (search for “glob”): https://rc.home-assistant.io/blog/2020/06/24/release-112/#all-changes


Oh I did miss that. Thanks!

There are discussions about how to find stuff in the database that takes a lot of space in the forums. Some of the stuff you’ll find takes a lot is space and is crap. For example the sun component was a huge offender of this until it was recently fixed.

Dig around and you’ll find something I’m sure.

trouble is I have a pzm setup to monitor my mains… that’s about 10 sensors recording values every 10 seconds. I want to keep this setup as the values are important to me but it throws up a bit of a snowstorm in the db so its hard to spot anything else that might be contributing a lot :slight_smile:

One option would be to exclude that data from the HA DB and include it in InfluxDB instead. InfluxDB seems to be a lot more efficient in it’s data storage. Frenk did a setup video for Influx and Grafana:

Seriously, I exclude everything and then item by item, include those that have any purpose for me.

how you exclude everything?
