## CREATING A FORECAST SENSOR USING THE SERVICE CALL

Some integrations (like the core [EnergyZero](<https://www.home-assistant.io/integrations/energyzero/>) integration) don't provice the forecast by default in an attribute. However they provide a service call to retrieve the prices. The example below shows how to setup a sensor to be used in the macro. The state of the sensor will be the current price, and the `price` attribute will contain the prices of yesterday, today and tomorrow (when available). Prices will be fetched every hour and on Home Assistant startup.

Notes:
* The example below is for EnergyZero, for EasyEnergy the service call is `easyenergy.get_energy_usage_prices` instead of `energyzero.get_energy_prices`
* The `config_entry` value in the service call will differ for each HA instance. The easiest way to get yours is to go to [Developer tools > Services](<https://my.home-assistant.io/create-link/?redirect=developer_services>) and select the service call. The make sure you are in UI Mode, and select the right config entry. Switch to YAML mode to see the config entry.
* When `incl_vat` is set to `true`, the EnergyZero API will use a 2 decimal precision, when set to `false` it will be 5 decimal precision. If you want more precise prices, set `incl_vat` to `false` (like in the example below)
