Dynamic pricing with 5-minute and 30-minute resolution. Current prices update every 5 minutes; forecasts are available at 30-minute resolution.
Setup:
- Get an API token from app.amber.com.au/developers
- Select Amber Electric during PowerSync setup
- Enter your API token
- Select your Amber site
Real-time wholesale pricing with native 5-minute NEM interval resolution. Localvolts provides marginal import and export prices (costsFlexUp / earningsFlexUp) with up to 24 hours of forward forecast data.
Setup:
- Obtain your API Key and Partner ID from Localvolts
- Select Localvolts during PowerSync setup
- Enter your API Key, Partner ID, and NMI (National Meter Identifier)
- Configure export boost and chip mode settings (optional)
| Option | Description |
|---|---|
| API Key | Your Localvolts API key (keep this secret) |
| Partner ID | Your Localvolts Partner ID |
| NMI | Your 10-digit National Meter Identifier. Use * for all authorized NMIs. |
- Prices are fetched every 5 minutes from the Localvolts API
- Import prices come from the
costsFlexUpfield (c/kWh) - Export prices come from the
earningsFlexUpfield (c/kWh) - Data is converted to Amber-compatible format internally, so all features work seamlessly:
- Smart Optimization (LP optimizer) with native 5-min resolution
- TOU tariff sync to Tesla/Sigenergy/FoxESS/GoodWe/Sungrow
- Battery export curtailment at negative prices
- Export boost and chip mode
- Forward forecast is limited to ~24 hours (the LP optimizer pads beyond this with the last known price)
- AEMO spike detection can be configured independently for price spike exports
- Localvolts does not provide Amber's
spikeStatusfield. If you want automatic battery discharge during NEM price spikes, enable the AEMO Spike Detection feature separately. -
'N/A'values in the API response (e.g. when no imports/exports in a forecast period) are treated as 0.0 c/kWh.
Uses AEMO wholesale pricing directly — no API token required. Prices update every 5 minutes from the AEMO NEM dispatch feed. You can optionally provide an Amber API token as an alternative price source.
| Source | Description |
|---|---|
| AEMO Direct (default) | Fetches wholesale prices directly from AEMO NEMWeb. No API key needed. |
| Amber API | Uses your Amber Electric API token for pricing data. Useful if you also have an Amber account. |
Flow Power bills using: Final Rate = Base Rate + PEA
PEA adjusts your rate based on when you consume relative to wholesale prices:
- Cheap wholesale (e.g. midday solar) → negative PEA → you pay less than the base rate
- Average wholesale → PEA near zero → you pay roughly the base rate
- Expensive wholesale (e.g. evening peak) → positive PEA → you pay more than the base rate
The PEA formula is: PEA = wholesale - TWAP - 1.7
Where:
- TWAP is the 30-day rolling Time Weighted Average Price (the market average)
- 1.7 c/kWh is the BPEA (Benchmark Performance Efficiency Adjustment)
PowerSync calculates the TWAP dynamically from actual wholesale prices. On a fresh install, it falls back to 8.0 c/kWh until enough data is collected (~1 hour / 12 samples).
| Sensor | Description |
|---|---|
| Flow Power Import Price | Current import rate in $/kWh (Base Rate + PEA) |
| Flow Power Export Price | Current export rate — Happy Hour rate during 5:30-7:30pm, 0 otherwise |
| Flow Power TWAP 30-Day Average | Rolling 30-day market average in c/kWh used in PEA calculation |
The TWAP sensor includes attributes: days_of_data, sample_count, using_fallback, and twap_dollars.
| Option | Description | Default |
|---|---|---|
| NEM Region | Your grid region (NSW1, QLD1, VIC1, SA1, TAS1) | NSW1 |
| Base Rate | Your Flow Power base rate in c/kWh (from your plan) | 34.0 |
| PEA Enabled | Enable PEA pricing adjustment | Yes |
| Custom PEA | Override the calculated PEA with a fixed value from your bill | Auto |
Static pricing with AEMO spike detection for VPP participation. No API token required. See Advanced Features for details on automatic discharge during price spikes.
Static time-of-use pricing for NZ electricity retailers. No API token required — rates are entered during setup from your plan details. All rates in NZD cents per kWh.
NZ TOU pricing follows the Electricity Authority's mandated TOU structure: 3-tier pricing (Peak, Shoulder, Off-Peak) with weekday-only peaks and weekends typically off-peak or shoulder.
| Retailer | Plan | Key Feature |
|---|---|---|

| Electric Kiwi | Standard TOU | 3-tier pricing (Hour of Power selected via Electric Kiwi app) |
| Contact Energy | Good Weekends | Free electricity on weekends |
| Contact Energy | Good Nights | Free electricity 9pm-midnight every night |
| Contact Energy | Good Charge | EV-focused with cheap overnight rate |
| Custom NZ TOU | Any plan | Enter your own rates for any NZ retailer |
Standard NZ TOU periods (used by most retailers):
| Period | Weekdays | Weekends |
|---|---|---|
| Peak | 7-9am, 5-9pm | — |

- Select New Zealand TOU as your electricity provider
- Choose your retailer (or Custom for any NZ plan)
- Select your distribution zone (Vector, Wellington, Orion, Powerco, Unison, Aurora, or Other)
- Review and adjust the pre-filled rates for your plan (or enter rates manually for Custom)
- Peak, Shoulder, Off-Peak import rates (NZD c/kWh)

- Daily supply charge (NZD c/day)
| Zone | Region |
|---|---|
| Vector | Auckland |
| Wellington Electricity | Wellington |
| Orion | Canterbury |
| Powerco | Waikato / Taranaki / Manawatu |
| Unison | Hawke's Bay / Rotorua / Taupo |
| Aurora | Otago / Southland |
| Other | Any other network area |
- Rates are stored as a TOU tariff schedule — the same format used by all other providers
- The LP optimizer uses your TOU rates to calculate optimal charge/discharge schedules, with weekday-only peaks handled automatically
- If you have a Tesla Powerwall, the TOU schedule is synced to the Powerwall for native tariff-aware behaviour
- Rates can be updated anytime via the integration options flow (Settings > Devices & Services > PowerSync > Configure)
- Electric Kiwi Hour of Power is not modelled in the TOU schedule — select your free hour via the Electric Kiwi app as usual
- Contact Good Weekends uses a 0 c/kWh rate for all weekend hours — the optimizer will prefer weekend consumption
- Contact Good Nights uses a 0 c/kWh rate for 9pm-midnight — the optimizer may shift load to this window
- Template rates are approximate starting points — always verify against your actual plan rates
