Sensors
The EnergyZero integration creates a number of sensor entities for both gas and electricity prices.
Energy market price
Every day around 14:00 UTC time, the new prices are published for the following day.
- The
currentandnext hourelectricity market price - Average electricity price of the day
- Lowest energy price
- Highest energy price
- Time of day when the price is highest
- Time of day when the price is at its lowest
- Percentage of the current price compared to the maximum price
Gas market price
For the dynamic gas prices, only entities are created that display the
current and next hour price because the price is always fixed for
24 hours; new prices are published every morning at 05:00 UTC time.
Services
The energy and gas prices are exposed using service calls. The services populate Response Data with price data.
