## Use cases
With the [energy dashboard](/energy) you can use the `current hour` price entity to calculate how much the electricity or gas has cost each hour based on the prices from EnergyZero. Or use one of the actions in combination with a [template sensor](#prices-sensor-with-response-data) to show the prices for the next 24 hours in a chart on your dashboard.
## Data updates
The integration will poll the EnergyZero API every 10 minutes to update the data in Home Assistant.
## Known limitations
The prices retrieved via the API are bare prices including VAT, however an energy company also charges other rates such as **energy tax** and **purchase costs**. The integration has no configuration option to add these values, but you could create a [template sensor](#all-in-price-sensor) for this.
## Sensors
The EnergyZero integration creates a number of sensor entities for both gas and electricity prices.

To calculate the all-in hour price, you can create a template sensor that calculates the price based on the current price, energy tax, and purchase costs.

## Removing the integration
This integration follows standard integration removal steps. If you also use the template sensors, you need to remove them manually.
