小白求助！怎么自锁开关状态

Clearwine

就是比如我打开开关以后，不能再执行打开命令，小爱回复该设备已打开，程序如下：
bool oState = false;
int counter = 0;

void miotPowerState (const String & state)
{
    BLINKER_LOG ("need set power state: ", state);
    if (state == BLINKER_CMD_ON) {  
        digitalWrite(0, HIGH);
        BlinkerMIOT.powerState("on");
        BlinkerMIOT.print();
        oState = true;
    }
    else if (state == BLINKER_CMD_OFF) {   
        digitalWrite(0,LOW);
        BlinkerMIOT.powerState("off");
        BlinkerMIOT.print();
        oState = false;
    }
}
