期望输出
High-temp alert + vent linkage:
  ts=1748736000 temp=26.5C: MONITOR {'temp': 26.5, 'vent_open': False}
  ts=1748736300 temp=29.0C: MONITOR {'temp': 29.0, 'vent_open': False}
  ts=1748736600 temp=33.5C: ALERT+COMMAND {'type': 'high_temp', 'temp': 33.5, 'cmd': 'open_vent', 'zone': 'A区'}
  ts=1748736900 temp=31.0C: MONITOR {'temp': 31.0, 'vent_open': True}
  ts=1748737200 temp=27.5C: COMMAND {'cmd': 'close_vent', 'zone': 'A区', 'temp': 27.5}
