I have this template sensor defined that totals the energy of two other energy sensors. I cannot select it as an individual device in the Energy dashboard config.
Here is the yaml ```
sensor:
- name: "3rd floor total energy"
unit_of_measurement: "kWH"
state_class: total_increasing
device_class: energy
state: "{{states('sensor.energy_monitor_circuit_22_energy')|float(0) + states('sensor.energy_monitor_circuit_24_energy')|float(0)|round(2) }}"
and here is the sensor in Dev tools.
The device_class and sensor_class and unit of measurement seem correct.
What am I missing?
