Need Help - setting optimal times for heat pump based on Temperature, electricity price and Solar

Configuration
12

Maybe I can help you.

  1. Install Emhass addon if you use hassos: EMHASS add-on: An energy management optimization add-on for Home Assistant OS and supervised

  2. In the emhass addon configuration use the default values.
    If you use Nordpool price data change “optimization_time_step”: 30, to “optimization_time_step”: 60,
    If you have Solar panels change to the correct sensor which output Watt produced:
    “sensor_power_photovoltaics”: “sensor.ecu_current_power”,

You must make a template sensor which output total consumed power in Watt without the deferral loads you want to control. My template is like this:

template:

  - sensor:      

      - name: "Power load no var loads"

        unique_id: fbfeef21-1aa3-4a54-b781-426f46fef597

        unit_of_measurement: W

        device_class:  power

        state: >

          {% set powerload = states('sensor.power_toraldasen_32') | float(default=0) %}

          {% set vvb = states('sensor.bryter_varmvannsbereder_electric_consumption_w') | float(default=0) %}

          {% set varmekabler = states('sensor.power_varmekabler') | float(default=0) %}

          {% set varmepumpe = states('sensor.strombryter_varmepumpe_electric_consumption_w') | float(default=0) %}

          {% set value = ( powerload - vvb - varmekabler - varmepumpe) | round(1,default=0) %}

          {{ value }}

which I use in Emhass config:
“sensor_power_load_no_var_loads”: “sensor.power_load_no_var_loads”,

This should give you a basic emhass config.

If you want to import the price data from Nordpool you must use the HA shell command Shell Command - Home Assistant. It is very easy to have wrong shell command. I use HA File editor to edit my shell command. Visual Studio are trying to fix without fixing the shell command.
Here are my shell commands:

shell_command:

  publish_data: "curl -i -H \"Content-Type:application/json\" -X POST -d '{\"custom_deferrable_forecast_id\": [

    {\"entity_id\": \"sensor.p_deferrable0\",\"unit_of_measurement\": \"W\", \"friendly_name\": \"Varmtvannsbereder\"},

    {\"entity_id\": \"sensor.p_deferrable1\",\"unit_of_measurement\": \"W\", \"friendly_name\": \"VKNystue-Varmepumpe\"},

    {\"entity_id\": \"sensor.p_deferrable2\",\"unit_of_measurement\": \"W\", \"friendly_name\": \"VKGmlstue-Bad2etg\"},

    {\"entity_id\": \"sensor.p_deferrable3\",\"unit_of_measurement\": \"W\", \"friendly_name\": \"VKBad1etg-Kjøkken-Gang\"}

    ]}' http://localhost:5000/action/publish-data"  

   

  trigger_nordpool_forecast: "curl -i -H \"Content-Type: application/json\" -X POST -d '{

    \"load_cost_forecast\":{{((state_attr('sensor.nordpool', 'raw_today') | map(attribute='value') | list  + state_attr('sensor.nordpool', 'raw_tomorrow') | map(attribute='value') | list))[now().hour:][:24] }},

    \"prod_price_forecast\":{{((state_attr('sensor.nordpool_uten_avgifter', 'raw_today') | map(attribute='value') | list  + state_attr('sensor.nordpool_uten_avgifter', 'raw_tomorrow') | map(attribute='value') | list))[now().hour:][:24]}}

    }' http://localhost:5000/action/dayahead-optim"

   

  ml_forecast_fit: "curl -i -H \"Content-Type:application/json\" -X POST -d '{\"num_lags\": 24}' http://localhost:5000/action/forecast-model-fit"

  ml_forecast_tune: "curl -i -H \"Content-Type:application/json\" -X POST -d '{}' http://localhost:5000/action/forecast-model-tune"

The shell command gives you services which you can use in automations:

service: shell_command.trigger_nordpool_forecast
data: {}

Here is my automation for the heat pump:

alias: "Emhass: Endre temperatur på varmepumpe. Sjekker hvert 5 minutt."
description: ""
trigger:
  - platform: time_pattern
    minutes: /5
condition:
  - condition: time
    before: "22:00:00"
    after: "05:00:00"
  - condition: state
    entity_id: binary_sensor.effektbegrenser
    state: "off"
action:
  - if:
      - condition: numeric_state
        entity_id: sensor.p_deferrable1
        above: 0.1
    then:
      - service: climate.set_temperature
        data:
          temperature: 23
          hvac_mode: heat
        target:
          entity_id:
            - climate.varmepumpe
    else:
      - service: climate.set_temperature
        data:
          temperature: 22
          hvac_mode: heat
        target:
          entity_id:
            - climate.varmepumpe
mode: single

David have done a great work with the emhass documentation. I recommend you read it before starting trying to use emhass. EMHASS: Energy Management for Home Assistant — emhass 0.4.8 documentation
If you need assistant I can help you more.

Here is my full emhass config: option.json · GitHub
