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!

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.

Select the downloaded JSON and paste it into a new workflow using Ctrl+V. 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.
