v0.4.0

[TrentHouliston]

HAEO v0.4.0

First stable release of the 0.4 series. This is a major release that introduces the power policy pricing system, dashboard cards for forecasts and network topology, deterministic optimization, and a large internal refactor into a standalone core package.

Caution

Back up your Home Assistant configuration before upgrading. This release includes one-way schema migrations (v1.3/v1.4) that restructure element configuration data. Once migrated, you cannot downgrade back to v0.3.x without restoring a backup.

Recommended steps: Take a full Home Assistant backup, upgrade, then check Settings → Devices & Services → HAEO to verify your elements and the new Policies subentry look correct. Check the Home Assistant log for any migration warnings.

Highlights

• ⚡ Power policies — define per-source pricing rules so the optimizer distinguishes solar export earnings, battery wear costs, and grid tariffs
• 📈 Forecast & topology Lovelace cards — visualize optimization forecasts and your energy network topology directly on your dashboard
• 🎯 Deterministic optimization — calibrated multiobjective solver gives consistent dispatch schedules every run
• 🔋 Sheddable loads & battery salvage value — loads can be curtailed when cost-effective; batteries value stored energy at the horizon end

⚠️ Breaking Changes

Pricing moves to power policies

Battery discharge wear costs, charge incentives, and solar production costs have moved from individual element configuration into the new Power Policy element. Existing configurations are migrated automatically (v1.3/v1.4 migrations), but verify after upgrading:

1. Open HAEO settings and confirm the new "Policies" subentry
2. Check that migrated rules match your previous pricing
3. Battery charge incentive prices are negated during migration — if you used entity-based incentives, check the log for warnings

Connections are now unidirectional

Connections are explicitly directional (source → target). Bidirectional paths use two connection entries. Existing bidirectional connections are migrated automatically; verify import/export paths after upgrading.

Entity unique IDs stabilized

Entity unique IDs are normalized and duplicate section-prefixed entities are cleaned up during migration. Update any automations or dashboards that reference old entity IDs.

Shadow price units changed to $/kWh (#424)

All shadow price sensors are now reported in $/kWh instead of $/kW. Entity IDs are unchanged; dashboards, templates, and automations that assumed the old unit need updating. Shadow prices now share the same unit as import/export tariffs, so no manual conversion is needed to compare them.

Full Changelog: v0.3.3...v0.4.0

---

This discussion was created from the release v0.4.0.

[purcell-lab]

Amazing work @TrentHouliston — and an impressive list of features all landing with documentation in sync. That kind of release discipline is genuinely rare in open source, where it's far more common to see features shipped first and the docs catching up two minor versions later (if at all).

A few things that stood out as particularly well-handled here:

• The breaking-changes section is exactly right. Calling out the v1.3/v1.4 migrations, the unit change on shadow prices ($/kW → $/kWh), and the directional-connection refactor up-front — with the explicit "back up before upgrading, no downgrade path" caution at the top — is the difference between users who upgrade cleanly and users who file 0.3 ↔ 0.4 confusion issues for a month.
• Policy pricing surfaced on element flows (Surface policy pricing fields on battery and load config flows #430, Apply surfaced policy defaults when frontend omits fields #442) is the right UX call. The standalone Policy flow is the powerful general case, but most users only want "tell HAEO my battery wear cost" — having that available without leaving the element screen lowers the configuration cliff a lot.
• Deterministic optimisation (Add lexicographic multiobjective optimization with calibrated blending #301) is underrated in this list. For anyone debugging dispatch behaviour, the calibrated-multiobjective approach removes a whole class of "why did it choose differently this run" questions and makes diagnostics replay actually meaningful.
• Shadow prices in $/kWh (Expose shadow prices in $/kWh (closes #423) #424) — finally. Sharing units with import/export tariffs means people can compare them directly in templates and dashboards without a mental ÷ Δt every time.
• The refreshed HAEO vs EMHASS comparison (Refresh installation docs and align documentation standards #464) is genuinely useful for the "which should I use" question that comes up in every Reddit thread.

Two small notes for anyone reading this before upgrading, based on running v0.4.1 here:

1. The Policies subentry check the release notes mention is worth doing carefully — the migration is faithful but the new structure is different enough that "verify it matches what I had" takes a few minutes per element if you had a non-trivial pricing setup.
2. If you have automations or templates that read shadow price sensors, search your config for the units before upgrading — entity IDs are unchanged so the breakage is silent until your numbers look off by ~12×.

Thanks for keeping the bar this high on a 58-star project with no funding behind it. The roadmap from here looks great.
