use an LLM to generate a "morning energy briefing"

[scruysberghs]

One for the ideas section:

EMHASS does the heavy lifting, ML forecasing, MPC optimiser etc. Most things can be automated (battery control, curtailment, EV charging etc) but I was thinking it would be nice to have the Assist/LLM integration generate a morning energy overview. Something like:

☀️ Good morning! Here’s your Smart Energy Briefing for today:

🔋 Battery status:
Your battery is currently at 68%. Based on today's solar forecast and price signals, EMHASS plans to fully charge it by 12:30 PM, then discharge to support your home during the peak evening hours.

🌤 Solar production forecast:

Total expected solar yield: 18.3 kWh

Peak production: 1:15 PM – 2:45 PM

Cloudy periods expected in the morning and late afternoon.

💰 Electricity prices today:

Cheapest hour: 2:00 PM – 3:00 PM at €0.09/kWh

Most expensive hour: 7:00 PM – 8:00 PM at €0.42/kWh

Average price today: €0.19/kWh, prices are highly dynamic, so avoid consumption between 6:00 PM and 9:00 PM.

📅 Planned deferrable appliances:
Based on optimization, here are the best times to run your appliances:

🧼 Dishwasher: Start around 1:30 PM (uses solar and cheap grid)

👕 Washing machine: Best between 12:00 PM and 2:00 PM

🌬 Dryer: Start between 2:30 PM and 4:00 PM

🚿 Boiler heating (hot water):
Scheduled to heat from 11:45 AM to 12:30 PM, fully covered by solar.

⚡ Curtailment warning:
If all loads are not activated, up to 3.4 kWh of solar may be lost due to excess production around midday. Consider preheating water or manually starting appliances if home.

🧠 Tip of the day:
Tonight’s prices are high—minimize evening consumption and charge your devices earlier in the day.

Have an energy-smart day! 🌱

Anyone else made/tried something like this yet?

meanwhile made a script that gathers all emhass sensor data trough the home assistant api and passes it to the openai API to genereate an overview every 2 hours to "explain" what EMHASS has planned... This is then shown in the UI in a Home Assistant markdown card...

Small snippet:

SENSORS = {
    "batt": "sensor.mpc_p_batt_forecast",
    "pv": "sensor.mpc_p_pv_forecast",
    "curtail": "sensor.mpc_p_pv_curtailment",
    "boiler": "sensor.mpc_p_deferrable0",
    "wash": "sensor.mpc_p_deferrable2",
    "pool": "sensor.mpc_p_deferrable3",
    "price": "sensor.mpc_unit_load_cost",
    "prod_price": "sensor.mpc_unit_prod_price",
    "soc": "sensor.mpc_soc_batt_forecast",
    "grid": "sensor.mpc_p_grid_forecast"
}
def get_sensor_data(entity_id):
    url = f"{HA_URL}/api/states/{entity_id}"
    response = requests.get(url, headers=HEADERS)
    response.raise_for_status()
    return response.json().get("attributes")

If anyone is interested I might clean it up and add some documentation.

Please publish your script here, it sounds interesting.
