v1.6.0
Adds Force Import - a dispatch mode that imports from the grid at a
configured target rate, dynamically adjusting battery charge power based
on live house load and PV production so total grid draw stays at the
target level. Mirrors the AlphaESS_Force_Import automation added in
upstream YAML v10.5.
New entities:
- switch.alphaess_inverter_force_import (mutex with all other dispatch switches)
- switch.alphaess_inverter_force_import_pause (suspends without cancelling)
- number.alphaess_inverter_force_import_power (kW target)
- number.alphaess_inverter_force_import_cutoff_soc (stops at this SoC)
- number.alphaess_inverter_force_import_duration (auto-off after this many minutes)
Dispatch uses a 30s dead-man window refreshed every 25s, so the inverter
self-clears if HA goes offline mid-session. Duration auto-off uses a
separate timer so the refresh cycle does not reset the countdown.
Removes Smart Charge switch and its Max Import Power number - Force Import
supersedes this with its own SoC target, duration, and pause control.
