# How do I get a monthly report on performance and energy use for my ZEB?

## Discover how to enable automated monthly energy reports that give you detailed insights into electricity use, heat output, and energy storage from your ZEB Heat Battery Boiler.

**Use this article to:**

- Understand the terms in your report: energy\_in, energy\_out, and core\_soc
- Enable or disable automated monthly performance reports sent directly to your email.

### **Monthly Reporting Overview**

Your monthly ZEB report gives you a detailed breakdown of your ZEB's energy usage and heat output each month, helping you understand and track your low-carbon home heating performance.

**What’s included in my report?** Every month you’ll receive a CSV file via email that shows:

- **energy\_in:** Electricity (Wh) used to charge your ZEB each half-hour
- **energy\_out:** Estimated heat (Wh) delivered during the same periods
- **core\_soc:** State of Charge — remaining stored energy (Wh) in the ZEB's core at the end of each half-hour interval

**Steps to enable or disable monthly ZEB data reports:**

1. Open the **tepeo app**.
2. Open the **tepeo app menu** (hamburger icon — three horizontal lines — at the top left of the screen).
3. Select **Account Settings**.
4. Locate the **Monthly ZEB data report** toggle.
5. Toggle the switch **ON** to receive monthly reports (or **OFF** if you wish to opt out).

Once toggled on, your performance report will be generated on the 1st of each month and emailed directly to the address linked to your tepeo account.
