Households following EnergyZero electricity prices get a choice between hourly and quarter-hourly readings in Home Assistant. The setting applies to today’s and tomorrow’s price data and the existing electricity sensors; the next-price reading follows the selected one-hour or 15-minute interval.
Changing the option reloads the integration automatically and preserves existing entity IDs. A related correction renames the sensor that counts cheaper or equally priced periods and removes its misleading hours unit. Templates or cards that depend on that unit need adjustment; comparisons using only the number do not.
This changes the detail of the price data, not how frequently Home Assistant checks for updates. Gas readings are unaffected, and the separate action for fetching energy prices still returns hourly values. Klaas Schoute contributes the feature, with approval from silamon.
