The problem it solves

Your energy provider sends usage data by email, but pulling those numbers into your home dashboard means opening spreadsheets and typing figures in by hand. Skip a few days and your energy tracking has gaps.

Who it fits

Homeowners tracking energy usage in Home Assistant who get meter data from E.ON by email.

How it works

  1. A new email from E.ON with a usage spreadsheet attached triggers the system
  2. The attached file is opened and the import and export energy figures are pulled out
  3. Fifteen-minute readings are grouped into hourly totals
  4. Home Assistant's energy statistics are updated with the hourly totals
  5. Your current meter readings are updated so your dashboard stays accurate
What you get

Your home energy dashboard staying accurate

You get your Home Assistant energy stats updated automatically from your E.ON meter emails.

What you get

Updated energy import and export statistics and meter readings inside Home Assistant.

What you need

A Gmail or IMAP email account and a Home Assistant instance with the Spook integration.

We can build this. But should you?

The hard question is not how to build it. It is whether this is the right thing to build first.

That is what a Fractional Chief AI Officer figures out with you, before anyone writes a line of code.
