MQTT sensors in energy dashboard through autodiscovery

Configuration
1

Hi

I’m trying to add some energy measurements done by an ESP32 and sent over MQTT to the HA energy dashboard, using MQTT autodiscovery for creating the sensors. Somehow I managed to get this working on 2021.6, but when I revisited this project on 2021.11 I could not get it working any more.

I create the sensor by sending {"name": "house total energy", "device_class": "energy", "state_class":"measurement", "unit_of_measurement":"kWh", "state_topic": "homeassistant/sensor/house_total_energy/state"} to homeassistant/sensor/house_total_energy/config.

This succesfully creates the sensor and it displays the state updates on the states page. On the energy dashboard however, it’s not available for selection.

I’ve tried adding "last_reset": "1970-01-01T00:00:00+00:00", "last_reset_topic": "homeassistant/sensor/house_total_energy" and "unique_id":"house_energy" to the payload, and changing "state_class" to "total_increasing", but to no avail.

I can’t see anywhere in the docs what I could be doing wrong. Is perhaps something missing in the MQTT autodiscovery?

Hi!
Did you solve this? I have the same problem.

To be available as an input to the energy dashboard, the sensor needs to be tracked by the recorder/history component. I only tracked sensors I included manually in my configuration.yaml. Adding it to history made the sensor available in the energy dashboard.

Also, I think my example message needs a unique_id field as well.
