Third alpha of the weather release. The headline is a new cost chip.
- What your energy costs, right now. When your Home Assistant Energy dashboard tracks a price, a cost chip joins the card and reads out your net spend in your own currency per hour (a negative rate means you're earning, selling your surplus). Tap it to bring its cost curve up on the timeline and around the house, and scrub the day to read the cost at any moment. It sits along the bottom as secondary info, with a fixed, configurable colour and icon like every other chip.
- Helios never invents a price: the chip only appears if a price is set in the Energy dashboard. This first pass covers a fixed price (so the curve spans your whole history); variable and multi-tariff pricing, plus the editor controls, follow in the next alphas.
Install: in HACS, open Helios and pick 2026.9.0-a2. The stable release stays 2026.8.3.
