Hold me! I'm dealing with that and haven't figured out how to fix it. How does the templating thing work? All my devices are Tuya devices, so you can imagine how quickly my database balloons up.
First thing - exclude recording of the devices. My method was to use a glob so I name devices/entity IDs specifically and they don't get recorded (in my case I used f_ as in "filtered" so devices become like "F Source Presence"), but you can add specific entities or use your own glob. In configuration.yaml I have this:
Then I created templates for my presence sensors, that just copy the state so I get history (yaml here, but can do through UI now too in the Helpers section, the import part is the template in the state key below):
You could also use a statistics sensor to get a moving average for numeric values and get history from them too (and reduce the noise by reducing the precision and having a larger time window). This is also available through the UI - Helpers.
Random one, but do you think it's possible to use the new label system to create the filter group?
Not according to the integration documentation: https://www.home-assistant.io/integrations/recorder/
The recorder integration only supports: domains, entities, events, and entity globs right now. I think that’s a good idea though, should check or create an enhancement request!
I went to create an enhancement request, but it's just creating a thread on their forums 😮💨
Iirc that’s where they start ERs yes - it’s easier to see, vote, and comment on them there compared to GitHub. It’s also the source for the month of WTF where it seemed like a lot of the easier ERs get addressed.
Guess I'll have to finally sign up to their forums
