智慧灯杆的定时音量设置可以通过发送指定格式的命令实现。例如,可以使用以下命令进行定时音量设置:
```
{"type": "timedVolume","task":{"_id":"591d519f5e3f190f697aaf18","defaultVolume":6,"name":"Timing Volume","items":[{"volume":10,"_id":"591d519f5e3f190f697aaf1a","schedules":[{"dateType":"All","startDate":null,"endDate":null,"timeType":"Range","startTime":"08:30","endTime":"18:00","filterType":"None","weekFilter":[],"monthFilter":[],"lng":"en"}]}],"id":"591d519f5e3f190f697aaf18","lng":"zh-CN"}}
```
其中,`defaultVolume`字段表示默认音量,`volume`字段表示定时时间音量,`startTime`和`endTime`字段表示定时的起始时间和结束时间。通过发送这个命令,可以设置智慧灯杆在指定的时间段内的音量。
