# Energy rates & financials

If you set **energy rates** in the app, the dashboard can show **financial insights**: cost of grid import, export credit, net cost, and savings. Rates are configured **per device** (inverter).

---

## Where to set rates

- **Menu → Account** → **Energy Rates** (or “Set import/export rates”), or
- From the dashboard, use the **Configure energy rates** (or “Set rates”) prompt in the financial section.

The form opens for the **currently selected device**. If you have multiple inverters, switch the device in the menu first if you want to set rates for another one.

---

## Simple rates (single import & export)

- **Import rate** - Price you pay per kWh for electricity from the grid (grid → house). Enter the number, e.g. `0.25`.
- **Export rate** - Price you receive per kWh for electricity you send to the grid (e.g. feed-in tariff). Enter the number, e.g. `0.08`.
- **Currency** - Choose your currency (e.g. GBP, USD, EUR). The app uses it for all cost and credit labels.

The app uses these to compute:

- **Import cost** - Grid consumption × import rate (for the selected period).
- **Export credit** - Export to grid × export rate.
- **Net cost** - Import cost minus export credit.
- **Savings** - Value of self-consumed solar (and optionally battery) at your import rate.

---

## Peak / off-peak (time-of-use)

If your tariff has **peak** and **off-peak** periods:

- Enable **Use peak/off-peak** (or equivalent) in the energy rates form.
- Set **Peak period** - e.g. start and end time (e.g. 7:00–23:00 = peak, rest = off-peak).
- **Peak import rate** and **Peak export rate** - Rates during peak.
- **Off-peak import rate** and **Off-peak export rate** - Rates during off-peak.

The app splits your consumption and export into peak and off-peak (using your **timezone** from Account) and applies the correct rate to each. Financial insights then show peak vs off-peak breakdown where relevant.

---

## What you see on the dashboard

- **Financial insights** section (when rates are set) shows:
  - Today’s (or period’s) import cost, export credit, net cost
  - Savings from self-consumption (and optionally battery)
  - For peak/off-peak: breakdown by period

- **Energy flow** and **charts** are unchanged; only the **financial** numbers depend on your rates.

---

## Updating or removing rates

- Open **Energy Rates** again and change the values, then save. To “turn off” financials, you can set rates to zero or leave them blank (behaviour may vary; the section may hide if no rates are set).
- Rates are stored per device; switching device loads that device’s rates.
