Statistics graph Card, what am I missing? | Home Assistant | Page 1

I'm pretty new to Home Assistant, but despite that I've (miraculously) achieved to create a rest integration that is now shown in Entities, with correct device class, and is now importing the numbers (pm2.5 and temp) into HA. I can see data in History and also in a History graph card.

But i would like to show the data in Statistics graph Card. The entities dropdown says "You don't have any statistics". I looked at the documentation, but I guess I'm missing the point of whatever I'm missing. What's the missing step? Do i need to set up a Recorder? Or some sort of aggregating component?

Thanks!

You will need to create a statistics helper from your entities. Statistic is available in the helper section

Ah ok... yeah, I since overcame the initial problem by adding device class and unit of measurement, so the entity then showed up in the dropdown. So in that sense I could configure the card correctly. But there 's still no statistics available and that's where your advice comes in 👍🏻

Sorry that's the wrong advice. Statistics helper has nothing to do with Long Term Statistics/Statistics graph.

#

To be recorded for statistics an entity must have a state_class, does your entity have a state_class attribute?

Yes, state_class: "measurement"

#

They show up now in the dropdown, so far so good

#

But still see this:

#

I have verified with History graph that data is coming in

#

Scratch that... i didn't revert the change per previous advice

#

in the card entity dropdown

Is entity listed in developer-tools/statistics? Does it have any issue?

ionic root Mar 23, 2025, 12:40 PM

#

listed and no issue

#

hmm... ok, when I switch to bar, i see something

#

i can choose Mean, min and max, all good

#

but line shows nothing etm

#

atm

#

Are you choosing hourly or 5m?

ionic root Mar 23, 2025, 12:43 PM

#

hourly

#

default

#

when i stat graph cars is added, does it take historical data or only from when card was created? wondering if I just need to leave it

#

ok, 5 min helped...

mint heron Mar 23, 2025, 12:44 PM

#

no when the card was created doesn't matter

#

if you just setup the entity (or fixed the state_class) though you probably need to wait another 20m till the next hour?

ionic root Mar 23, 2025, 12:47 PM

#

ah yeah ok... well, history graph has been showing data for a while now. However, state_class and unit is a very recent change (HA let me fix old values from "" to the new unit which is pm25 and C)

Yeah it won't start recording LTS until you had all that sorted.
