• There are many function you can do just visit zk protocol to see the command and put it in executeCmd function already exist in the ZKLIB

• [This repo contain the cmd of many machine ] (https://github.com/adrobinoga/zk-protocol/blob/master/protocol.md)

    async executeCmd(command, data=''){
        return await this.functionWrapper(
            ()=> this.zklibTcp.executeCmd(command, data),
            ()=> this.zklibUdp.executeCmd(command , data)
        )
    }

    // unlock the door  
    executeCmd(CMD.CMD_UNLOCK, '')
