v2.2.0 — See why, try what-if

📦 Stable Release

Changes since 2.1.0

The second stable release of the 2.x line. Needs Home Assistant 2026.2.0 or newer. Works on 2026.11, where HACS becomes Settings → Marketplace.

🚀 Features and enhancements

• Try a what-if on your own days — another battery, more solar, a different price, replayed against your recorded history (Simulation tab).
• Every change SEM makes says why — the Why? card and the logbook give each one a plain sentence, in your language.
• Settings and the EV tab show only what you need — Everyday holds the common controls; All settings holds the rest.
• Setup shows what SEM found as live watts, and asks one question when it is unsure of your grid meter.
• More found on its own: outdoor temperature, grid CO₂, go-eCharger, ENTSO-e prices, Helios Forecast, NRGkick and OpenEVSE.
• A phase or grid-operator limit sheds ordinary loads too, not only chargers.
• A heat pump or load can carry its own tariff and meter.
• The Home diagram shows the car's charge level (by @OddmarDam in #1212, #1220).

New features are off until you switch them on. One exception: if the phase guard was already on, it now sheds ordinary loads too.

🐛 Bugfixes

Grid and battery sign errors on homes with a split meter or a second battery, a battery sale counted as solar, and a counter step that could grow a month or year total. Full list in the CHANGELOG.
