Statistics Graph Card - no statistics found

Configuration
#1

Hi,

I have been looking around for a solution on this forum but can’t find any. When i setup a statistic sensor in a stastics graph card it keeps saying “no statistics found” and i dont no why. I have these intergrations setup

  • Recorder
  • History

This is my sensor:

---
sensor:
  platform: statistics
  entity_id: sensor.basement_humidity
  name: basement_humidity_statistics

This is my config for the card:

---
title: Climate
icon: mdi:home-thermometer
path: climate
type: sidebar
cards:
  type: statistics-graph
  title: "Basement"
  entities:
    - sensor.basement_humidity_statistics

I’m assuming it’s set up properly as it collects data, but why is it not showing any data in the frontend?

Same for me I don’t think The statistics graphs card works with statistic sensors. try using a regular graph card or entities card, maybe even a auto-entities card.shoot even a gauge card will work.

#3

According to the DOCS. The state_class property must be set to measurement, and the device_class must not be either of energy, gas, or monetary

#4

and also That’s caused by a bug in the integration providing the entity. Integrations need to configure their entities correctly so Home Assistant knows that we need to track statistics for it and how.

Thanks i was confused, statistics sensor and statistics graph card suggest they have something to do with each other but apparently they are not. I have to look further to find out how to setup the sensor so that it can work in the statistics graph card.

Were you able to work it out? I also followed the steps outlined in the docs, but still get the same error.

#7

is anyone logging this as a bug so that it can be fixed ?

It’s not a bug. You need to add state_class: with the proper long term statistic setting to your sensor. Some integrations do not allow this in their configuration. When that happens, you need to customize it via customize.yaml.

#9

How would you do this? I’ve had errors adding in the template sensor config, and in customize.yaml too.
I have local tuya energy monitoring set up, but no statistics history, Should it be added like this? It gives an ‘extra keys not allowed’ error. Thanks.

smart_plug_voltage:
  state_class: measurement

Hey, I have two Aqara Temperature Sensors added via deconz. Both are woring, i.e. showing their temperature in HASS.
But if I add them to a statistics graph, only one shows up, the other doesn’t. Also, when I open the popup information of the one not working, it doesn’t show any data and saying “no statistics found”.

The Dev State insopector shows the same attributres for both:

state_class: measurement
on: true
unit_of_measurement: °C
device_class: temperature
friendly_name: OG Thermometer

Any ideas on how to fix that?

Seeing this with an ESPHome device I added…if I tap it says not found, if I go to the “show more” it shows fine.

sensor:

  # Water pressure analog signal in scale
  - platform: adc
    pin: SVP
    name: "Water Pressure"
    id: water_pressure
    unit_of_measurement: "psi"

    device_class: "pressure"
    state_class: "measurement"
    accuracy_decimals: 0
    update_interval: 1s
    # Required for ESP32 to measure 3.3v
    attenuation: 11dB
    #force_update: true
    #internal: true
    filters:
      - calibrate_linear:
          # Zero-Pressure Calibration:
          - 0.3430 -> 0.0
          # Working-Pressure Calibration:
          - 1.91800 -> 58.0
      - sliding_window_moving_average:

          send_every: 1
    on_value:

          format: "*CALIBRATE Pressure LB-Correction: adc_raw=%.4f / output=%.4f lb"
          args: [ 'id(water_pressure).raw_state', 'id(water_pressure).state' ]

I have the same problem with grouped sensors

#13

Not sure which screen I found it on but I stumbled onto somewhere in HA that it had some of my sensors with a “Fix” button saying units had changed.

When I was trying to figure out I noticed my pressure sensor was in the list…hitting “Fix” saying the DB units didn’t match the sensor units seems to have cured the bad graph!

It wasn’t under “Repairs” and it wasn’t under the “Integrations > Entities”…I wish I could figure out how I got there. I think it was via a totally unrelated problem that popped up in “Repair” page. It was also a page that let me “Remove” some stuff that was long missing from the database.

Maybe someone else recognizes the page I’m describing?

Oh, that must be DevTools → Statistics

Looks great. Could you tell what exactly happens when I remove all old data? Dies ist only remove the old data with the old entity or everything until now?

In my case I didn’t see any adverse effect with removing the data, and afterward everything “just worked” with my graphs appearing properly.

I do only keep 2 weeks of sensor history though so I wasn’t very concerned about losing history by deleting anything.
