set_battery_discharge
Configure battery discharge schedules and cutoff levels for Alpha ESS energy storage systems to optimize energy usage and manage power flow.
Instructions
Set battery discharge configuration for a specific Alpha ESS system.
If no serial provided, auto-selects if only one system exists.
Args:
enabled: True to enable battery discharge, False to disable
dp1_start: Start time for discharge period 1 (HH:MM format, minutes must be :00, :15, :30, :45)
dp1_end: End time for discharge period 1 (HH:MM format, minutes must be :00, :15, :30, :45)
dp2_start: Start time for discharge period 2 (HH:MM format, minutes must be :00, :15, :30, :45)
dp2_end: End time for discharge period 2 (HH:MM format, minutes must be :00, :15, :30, :45)
discharge_cutoff_soc: Percentage to stop discharging battery at (0-100)
serial: The serial number of the Alpha ESS system (optional)
Returns:
dict: Result of discharge configuration update with success statusInput Schema

Implementation Reference
- main.py:878-954 (handler)The core handler function for the 'set_battery_discharge' tool. It is decorated with @mcp.tool(), which registers it as an MCP tool. The function handles serial auto-discovery, authenticates with the Alpha ESS API, and calls updateDisChargeConfigInfo to set the discharge parameters.
