Implementation Reference
- src/domoticz_mcp/server.py:626-642 (handler)The `set_temperature_setpoint` tool handler function. It accepts a `setpoint` (float, Celsius), optional `idx` or `name`, resolves the device index, and sends a request to the Domoticz API with param=setsetpoint to set the thermostat temperature.

No separate registration file exists; the decorator registers it automatically.
