Import E.ON W1000 energy meter data to Home Assistant with Spook integration

UPDATES:

• 2025-12-03 fix JS code in calculate hourly sum node

E.ON W1000 → n8n → Home Assistant (Spook) “Integration”

This workflow processes emails from the E.ON portal containing 15-minute +A -A (import/export) data and daily 1.8.0 2.8.0 meter readings.
It extracts the required columns from the attached XLSX file, groups the 15-minute values by hour, then:

• updates the Spook/Recorder statistics under the IDs sensor.grid_energy_import and sensor.grid_energy_export, and
• sets the current meter readings for the entities input_number.grid_import_meter and input_number.grid_export_meter.

> You may need to modify the workflow if there are changes in how E.ON sends scheduled exports. If the exported data format changes, please report it on Github!

Requirements

  • HACS addon available here: Rbillon59/home-assistant-addons
  • Official n8n Docker Compose template
  • Simplified n8n Docker Compose template available on Github
• (For Gmail) Gmail API authentication (OAuth2) read-only email access to the account receiving the messages
  • Setup guide available here
• (For IMAP) IMAP provider credentials
• Home Assistant access via Long-Lived Access Token or API key
  • Setup guide available here
• Spook integration
  • Documentation and installation guide available here

E.ON Portal Setup

1. Create a scheduled export on the E.ON portal with the following parameters:
   • Under the Remote Meter Reading menu, click on the + new scheduled export setting button.
     • Specify POD identifier(s): choose one of the PODs you want to query.
     • Specify meter variables: select the following:
       • +A Active Power Consumption
       • -A Active Power Feed-In
       • DP_1-1:1.8.0*0 Active Power Consumption Daily Reading
       • DP_1-1:2.8.0*0 Active Power Feed-In Daily Reading
     • Export sending frequency: daily
     • Days of historical data to include: recommended 7 days to backfill missed data.
     • Email subject: by default, use [EON-W1000]. If processing multiple PODs with the workflow, give each a unique identifier.

Home Assistant Preparation

1. Create the following input_number entities in configuration.yaml or via Helpers:

input_number:
  grid_import_meter:
    name: grid_import_meter
    mode: box
    initial: 0
    min: 0
    max: 9999999999
    step: 0.001
    unit_of_measurement: kWh
  grid_export_meter:
    name: grid_export_meter
    mode: box
    initial: 0
    min: 0
    max: 9999999999
    step: 0.001
    unit_of_measurement: kWh

> If you name the entities differently, make sure to reflect these changes in the workflow.

2. Create the following template_sensor entities in configuration.yaml or via Helpers:

input_number:
  grid_import_meter:
    name: grid_import_meter
    mode: box
    initial: 0
    min: 0
    max: 9999999999
    step: 0.001
    unit_of_measurement: kWh
  grid_export_meter:
    name: grid_export_meter
    mode: box
    initial: 0
    min: 0
    max: 9999999999
    step: 0.001
    unit_of_measurement: kWh

>If you name the entities differently, make sure to reflect these changes in the workflow.

2. create the following template_sensor entities in config.yaml or via Helpers:

template:
  - sensor:
      - name: "grid_energy_import"
        state: "{{ states('input_number.grid_import_meter') | float(0) }}"
        unit_of_measurement: "kWh"
        device_class: energy
        state_class: total_increasing
      - name: "grid_energy_export"
        state: "{{ states('input_number.grid_export_meter') | float(0) }}"
        unit_of_measurement: "kWh"
        device_class: energy
        state_class: total_increasing

> If you name the entities differently, make sure to reflect these changes in the workflow.

n8n import and authentication

1. importing the workflow

   • In n8n → Workflows → Import from File/Clipboard → paste the JSON.
   • Select the downloaded JSON and paste it into a new workflow using Ctrl+V.

2. Set up n8n Credentials The credentials must be configured in the Home Assistant and Gmail nodes. The setup process is described in the Requirements section.
