Electricity Cost Profiles — proposed first version Users should be able to create a custom profile with: Fixed or dynamic base electricity prices Provider-specific markups and fees Day-of-week rules Custom time periods, with ability to create multiple tariff slots per day Monthly consumption brackets Choice between marginal tiers and one-rate-for-the-whole-month tiers Taxes, VAT, grid charges, and fixed monthly fees Separate import and export calculations Billing-cycle start date and timezone Effective dates for tariff changes The profile should power both: Homey Energy cost monitoring and reporting Flow conditions and triggers , such as running appliances when the effective cost is below a chosen threshold A provider database could remain as an optional shortcut, but custom profiles would be the essential foundation. This avoids incomplete regional coverage and reduces the need to maintain every provider’s tariff structure centrally.

Instead you’d probably be very interested in the Power by the Hour community app. Many of your bullets are covered.

Power by the Hour seems relevant here, especially since it already covers several of the tariff options mentioned. It may be worth comparing its current features with the specific requirements in this proposal.

+1 from Sweden. A concrete example of why time-based slots matter: our grid operator’s time-of-use tariff charges about 76.5 öre/kWh incl. VAT on weekdays 06-22 in Jan-Mar and Nov-Dec, and about 30.5 öre/kWh at all other times. On top of that come the spot price, a supplier markup, energy tax and 25% VAT, and since 2025 spot is settled per 15 minutes. The current Dynamic price formula can’t vary by time of day, so Homey Energy can’t show the real cost for us. Custom profiles with weekday and hour rules, plus a base price that stays dynamic, would solve this. I’d also like to use the effective price as a Flow condition for heat pump control.

The new V9 of Power by the Hour should cover all this.
