Known Issues This Skill Prevents

1. Incorrect state_class values (must be total, total_increasing, or measurement)
2. Missing device_class: energy on energy sensors
3. Wrong state_class for utility_meter entities (must be total_increasing)
4. Using unit_of_measurement: kWh without state_class (breaks statistics)
5. Forgetting to enable statistic collection in configuration.yaml
6. Configuring solar sensors without battery tracking for self-consumption
7. Grid monitoring with mismatched sensor pairs (consumption vs return)
8. Utility meter cycle settings that don't align with billing periods

Quick Start

Step 1: Configure Energy Sensors

# configuration.yaml
template:
  - sensor:
      - name: "Total Energy Consumed"
        unique_id: total_energy_consumed
        unit_of_measurement: kWh
        device_class: energy
        state_class: total_increasing
        state: "{{ (states('sensor.energy_meter') | float(0)) }}"

      - name: "Solar Production"
        unique_id: solar_production
        unit_of_measurement: kWh
        device_class: energy
        state_class: total_increasing
        state: "{{ (states('sensor.solar_meter') | float(0)) }}"

Why this matters: Proper state_class enables Home Assistant to automatically create statistics and energy dashboard integration. Without it, your sensors won't appear in the energy dashboard.

Step 2: Set Up Utility Meter for Billing Cycles

# configuration.yaml
utility_meter:
  daily_energy:
    source: sensor.total_energy_consumed
    cycle: daily
    offset: [hours: 0]

  monthly_energy:
    source: sensor.total_energy_consumed
    cycle: monthly
    offset: [days: 0]

  daily_solar:
    source: sensor.solar_production
    cycle: daily
    offset: [hours: 0]
