“Statistics sensor” from an “Filter sensor” don’t work (unavailable)

[Gferretta]

The problem

Hi

I have an:

1. Sonoff TH16 Temperature and Humidity sensor
2. An Template sensor over last (1) for accuracy setting if needed
3. An Filter sensor over last (2) for low/high pass

What I am wanting to do is have statistical sensors defined on the filter sensor (3) to be able to save the minimum/maximum/average values according to different time values.

The problem is that in the statistics, when using the filter sensor (3), I ALWAYS receive "unavailable".

But if I use the template sensor (2) in the statistics, I immediately begin to have values and they adjust correctly.

My question is enlarged because I have correctly saved the history on the filter (3) since I can use the statistics card on that sensor in lovelace.

I have followed all the new settings defined in: https://www.home-assistant.io/integrations/statistics/

Any idea if it can or am I doing something wrong? It's Possible to do?

Thanks

Example:

(1)
sonoff:
   sensor: sonoff_123456789

(2)
template:
  - sensor:
     - name: humidity_th16
       unique_id: hum1
       device_class: humidity
       state_class: measurement
       unit_of_measurement: '%'
       state: >
          {{ (states('sensor.sonoff_123456789_humidity')|float(0)*0.98)|round(1) }}

sensor:
(3)
- platform: filter
  name: "FHum1"
  entity_id: sensor.hum1
  filters:
    - filter: lowpass
      time_constant: 20
      precision: 1
(4.a)  DON'T WORK
- platform: statistics
  name: "MAX FHum1 for 24 hours"
  entity_id: sensor.fhum1
  state_characteristic: value_max
  max_age:
    hours: 24
  sampling_size: 200
  precision: 1
(4.b)  WORK OK
- platform: statistics
  name: "MAX Hum1 for 24 hours"
  entity_id: sensor.hum1
  state_characteristic: value_max
  max_age:
    hours: 24
  sampling_size: 200
  precision: 1

Hey there @fabaff, @ThomDietrich, mind taking a look at this issue as it has been labeled with an integration (statistics) you are listed as a code owner for? Thanks!

Hello @Gferretta,
thanks for posting the issue. Your config looks reasonable to me. This is probably not a bug with the integration.

Your statistics sensor 4a "does not work" you say. Not sure what that means.

Please try the following code. Let sensor.fhum1 collect values for a few minutes, then send us a screenshot of the graph and attributes the statistics sensor

sensor:
  platform: filter
  name: "FHum1"
  entity_id: sensor.hum1
  filters:
    - filter: outlier
        window_size: 3
        radius: 999

- platform: statistics
  name: "MAX FHum1 for 24 hours"
  entity_id: sensor.fhum1
  state_characteristic: count
  max_age:
    hours: 24
  sampling_size: 9999

What I meant by "NOT working" is that it does not bring the maximum/minimum values of an "Filter"

I have made the changes you have proposed and I will show you the results shortly
Regards and thank you very much
