ESPHome & MQTT: No Long term statistics

Hello together,
i have many ESPHome Devices in Home Assistant for Temp and Humi measurement.
These devices are available in the long-term statistics.

Some devices are located at a distance and send the data via MQTT.
These devices are not available in the long-term statistics.

I tried this in the ESPHome YAML, but it does not work.

  - platform: ina226
    address: 0x40
    shunt_resistance: 0.002 ohm
      icon: mdi:flash-auto
      name: "${sensorname1} Strom"
        - lambda: |-
            float MIN_VALUE = 0;
            float MAX_VALUE = 30.0;
            if (MIN_VALUE <= x && x <= MAX_VALUE) return x;
            else return {0};
      icon: mdi:solar-panel-large
      name: "${sensorname1} Leistung"
       device_class: "energy"
      state_class: "measurement"
      icon: mdi:flash
      name: "${sensorname1} Bus Spannung"
       device_class: "voltage"
      state_class: "measurement"
      icon: mdi:flash
      name: "${sensorname1} Shunt Spannung"
       device_class: "voltage"
       state_class: "measurement"
    max_current: 20.0A
    update_interval: 10s

Under Developer Tools the attribute state_class is not shown:


I made this change for all temperature and humidity sensors that send their data via MQTT:

       last_reset: '1970-01-01T00:00:00+00:00'
       device_class: temperature
       state_class: measurement
       last_reset: '1970-01-01T00:00:00+00:00'
       device_class: humidity
       state_class: measurement

It is now possible to display the devices in the long-term statistics. But is that the right way?

Good question. I hope we get an answer

It’s easier than relying on customize for each sensor, so: yes,

I did see a way to add this to mqtt discovery by publishing a retained topic but that would depend on your sensors being discovered and not defined in yaml.

Thanks for the information. I am of the opinion that this should be transmitted via MQTT in the same way as with the native API.

@OttoWinter Is this issue with the MQTT component being looked in to?

This should’ve been resolved in ESPHome 2021.8.

Please don’t demand people answer you. See point 16 here.

I’m sorry. It wasn’t meant as a demand. Different communities, different rules I suppose.
