heating_compressors_0_sensors_power_value returns 0-100% of rated compressor power, not watts. heating_compressors_0_power_value is the constant rated power in kW (10 kW). Actual watts = sensors% × kW × 10. Idle threshold of 20 remains correct: values are either 0% (idle) or ≥27% (running), so 20 cleanly separates them. Grafana panel updated to show computed actual watts using the formula. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
