Simplifies the Sunsynk setup instructions to recommend direct single timer slot control, which requires no Sunsynk-specific Home Assistant automations or template sensors. This approach has been running reliably since March 2026, including charge windows that cross midnight, and avoids the timer overlap issues encountered with the six-slot configuration. The six-slot method and the previous automation-based approach remain documented as alternatives. The standard utility_meter block is still required, as it is for every Predbat installation — it is not Sunsynk-specific. Requested by @gcoan in discussion springfall2008#4609.

Clarify Predbat's control over Timer 1 and its charging parameters.

From v9.3.7, Predbat respects user-configured time entities in apps.yaml rather than replacing them with internal dummies. For Sunsynk inverters, map charge_start_time and charge_end_time to Predbat's own sensors (sensor.predbat_sk_0_charge_start_time / _end_time) — these accept the full HH:MM:SS format Predbat uses. Mapping directly to the Sunsynk select entity will fail because it only accepts HH:MM." |
