Home Assistant Battery Automation Notes (2025-10-10)

Work performed on delly host, LXC VMID 101 (Home Assistant). Pulse codebase unaffected.
Root cause: malformed automations.yaml caused five restarts between 00:23–00:33 BST.
Fixes applied:
- Restored automation backups.
- Replaced pyscript.solis_set_charge_current calls with number.set_value targeting number.solis_rhi_time_charging_charge_current.
- Removed invalid source: attributes from number.set_value actions.
Validation:
- Triggered key automations (automation.free_electricity_session_maximum_charging, automation.intelligent_dispatch_solis_battery_charging, automation.emergency_low_soc_protection, EV guard hold/refresh/release).
- Observed expected charge-current adjustments (100 A car slots/free session, 25 A emergency, 5 A guard) and matching system logs.
Defaults restored: overnight slot 23:30–05:30.
Backups: /var/lib/docker/volumes/hass_config/_data/automations.yaml.codex_source_cleanup_20251010_090205 (do not delete).
Testing helpers: API token stored at /tmp/ha_token.txt inside VM; use pct exec 101 -- bash -lc '...' for commands.
Final state: charge current reset to 25 A; EV guard sensor off.
