Sensor data not showing in Statistics Graph

Configuration
1

Hello,
I’m very new to the world of home assistant, be gentle :slight_smile:
I’m trying to create a plot with data from my own temperature sensors and the publicly available bureau of meteorology.
In Developer Tools / States I can find those 4 entities:

- sensor.entrance_sensor_temperature
- sensor.living_room_sensor_temperature
- sensor.upstairs_office_temperature
- sensor.weather_temperature

They all show a sensible number under State and have the following Attributes

- unit_of_measurement: °C
- device_class: temperature
- friendly_name: <A friendly name>

The first 3 also have:
- state_class: measurement

sensor.weather_temperature is coming from my sensors.yaml, which I’ve included in my configuration.yaml via sensor: !include sensors.yaml. It looks like this:

- platform: template
  sensors:
    weather_temperature:
      friendly_name: "Weather Temperature"
      unit_of_measurement: "°C"
      device_class: "temperature"
      value_template: "{{ state_attr('weather.marmion', 'temperature') }}"

I have made a new view in my Dashboard of type “Panel”. It’s using card_mod and looks like this:

type: vertical-stack
cards:
  - type: statistics-graph
    chart_type: line
    title: Day
    period: 5minute
    days_to_show: 1
    entities:
      - entity: sensor.living_room_sensor_temperature
        name: Living Room
      - entity: sensor.entrance_sensor_temperature
        name: Entrance
      - entity: sensor.upstairs_office_sensor_temperature
        name: Upstairs
      - entity: sensor.weather_temperature
        name: Outside
    stat_types:
      - max
    card_mod:
      class: middle
  - type: statistics-graph
    chart_type: line
    title: Week
    period: hour
    days_to_show: 7
    entities:
      - entity: sensor.living_room_sensor_temperature
        name: Living Room
      - entity: sensor.entrance_sensor_temperature
        name: Entrance
      - entity: sensor.upstairs_office_sensor_temperature
        name: Upstairs
      - entity: sensor.weather_temperature
        name: Outside
    stat_types:
      - max
    card_mod:
      class: middle

Unfortunately, I can’t get the data from sensor.weather_temperature to show:

What am I missing?

You’ll need to add its state_class as measurement in order for statistics to process it.

I tried that.
When I change my sensor config to this:

- platform: template
  sensors:
    weather_temperature:
      friendly_name: "Weather Temperature"
      unit_of_measurement: "°C"
      device_class: "temperature"
      state_class: "measurement"
      value_template: "{{ state_attr('weather.marmion', 'temperature') }}"

I’m getting the following error when I check my configuration:
Invalid config for [sensor.template]: [state_class] is an invalid option for [sensor.template]. Check: sensor.template->sensors->weather_temperature->state_class. (See ?, line ?).

You are using the old style template definition. Try using the new style.


# Example configuration.yaml entry with two sections
template:
  # Define state-based template entities
  - sensor:
      ...

Yep. This is why you don’t use the old style template sensors. Even though they still work they do not support new features, like in this case, long term statistics.

Thanks for your input, @PeteRage and @tom_l
Using the new style fixed it. :+1:
