Tariff Update Groups** Tariff Update Groups link pricing providers (`dap`, `dap15`, `dapg`) to consumer summarizer devices (`power`, `gas`). - Assign a group number (e.g. `1`) to both the pricing device and the summarizer device. - Whenever prices update or time slots change, the pricing device automatically broadcasts updated tariffs to all summarizers in that group. ### **2. Annual Budget Distribution Models** PBTH compares real-time usage against annual reference targets using seasonal distribution models: - **Linear:** Equal allocation for each month (30.4 days/month). - **Dutch 2023 Price Ceiling (`el_nl_2023` / `gas_nl_2023`):** Weighted according to seasonal heating and household consumption profiles. - **Solar PV:** Weighted according to typical European solar irradiance curves. ### **3. Virtual Meter Setup** For source devices with non-standard capability names or split tariffs: 1. Select **VIRTUAL\_METER** during driver pairing. 2. Push cumulative meter readings via a Flow using the action **Update Virtual Meter Value**. 3. Pass total net cumulative energy: $\text{kWh}_{\text{total}} = (\text{consumed}_{\text{high}} + \text{consumed}_{\text{low}}) - (\text{returned}_{\text{high}} + \text{returned}\_{\text{low}})$. * * * ## **📡 Market Data Providers** PBTH integrates data directly from official European energy market exchanges: - **Electricity Spot Prices:** [ENTSO-E Transparency Platform](https://transparency.entsoe.eu/) & [Nordpool](https://www.nordpoolgroup.com/) - **Gas Spot Prices:** [EEX (European Energy Exchange)](https://www.eex.com/) & [EasyEnergy](https://www.easyenergy.com/) - **AI Price Forecasting:** [Stekker.ai](https://stekker.ai/) * * * ## **👨‍💻 Developer API** Other Homey apps and HomeyScript can query prices or listen for real-time slot pushes via the PBTH Inter-App API: - `GET /dap-prices` — fetch all current future price slots. - Realtime event `dap-prices-updated` — emitted on slot changes and price updates. See **[README.dap-api.md](https://github.com/gruijter/com.gruijter.powerhour/blob/master/README.dap-api.md)** for full API reference and code examples. * * * ## **❤ Donate & Support** If Power by the Hour helps you save energy and money, consider supporting development: [![Donate with PayPal](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/1/4/1423e3c95178543a5c372db26303450941a6dbbc.svg)](https://www.paypal.me/gruijter) --- _[View the full topic](https://community.homey.app/t/app-pro-power-by-the-hour-insights-per-hour-day-month-and-year/20535)._
