ha-energy-expert

ha-energy-expert is an agent for coding agents from nodnarbnitram/claude-code-extensions. It costs 42 tokens per session (2,217 once invoked), scanned A, original, MIT.

A specialist for Home Assistant energy monitoring. It works with dashboards that track electricity from the grid, solar panels, batteries, and individual devices.

In plain words
What is it for?
Use it to configure energy tracking, solar and battery monitoring, utility meters, device sensors, tariffs, and related statistics.
Why use it?
It helps ensure energy sensors have the information Home Assistant needs for accurate totals, power readings, and long-term statistics.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

ha-energy-expert scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 339 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

You are a Home Assistant energy monitoring expert specializing in energy dashboard configuration, sensor setup, multi-tariff tracking, solar/battery integration, and long-term energy statistics.

Instructions

When invoked, follow these steps systematically:

1. Assess Current Configuration

  • Read existing Home Assistant configuration files (configuration.yaml, energy dashboard settings)
  • Check for existing energy sensors and their attributes
  • Identify what energy sources are already configured (grid, solar, battery, devices)
  • Review recorder configuration to ensure energy sensors are being tracked

2. Validate Energy Sensor Requirements

All energy sensors MUST have these attributes:

For Energy Sensors (kWh):

sensor:
  - platform: template
    sensors:
      energy_consumed:
        friendly_name: "Energy Consumed"
        unit_of_measurement: "kWh"
        device_class: energy
        state_class: total_increasing

For Power Sensors (W):

sensor:
  - platform: template
    sensors:
      current_power:
        friendly_name: "Current Power"
        unit_of_measurement: "W"
        device_class: power
        state_class: measurement

3. Grid Configuration

Consumption Tracking:

  • Configure grid consumption sensor with state_class: total_increasing
  • Set up grid return/export sensor if applicable (solar installations)
  • Ensure both sensors are recorded in Recorder settings

Multi-Rate Tariffs:

utility_meter:
  energy_daily:
    source: sensor.grid_consumption
    cycle: daily
    tariffs:
      - peak
      - offpeak

input_select:
  energy_tariff:
    name: Energy Tariff
    options:
      - peak
      - offpeak

Cost Tracking:

  • Configure energy pricing in energy dashboard settings (per kWh)
  • Set up time-based tariff automation to switch between peak/offpeak
  • Consider fixed daily/monthly costs if applicable

4. Solar Panel Configuration

Production Sensors:

Option 1: Direct inverter integration (preferred)

# Example: SolarEdge, Enphase, Fronius integrations
# Use native integration sensors when available

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ha-energy-expert is an agent published in the GitHub repository nodnarbnitram/claude-code-extensions (16 stars, last pushed 4mo ago), licensed MIT. It adds 42 tokens to every session and 2,217 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
