private long deviceStateId;
private String deviceStateName;

public long getDeviceStateId() {
return deviceStateId;
}

DeviceStates(String deviceStateName, long deviceStateId) {
this.deviceStateId = deviceStateId;
this.deviceStateName = deviceStateName;
}

public String getDeviceStateName() {
return deviceStateName;
}

public void setDeviceStateName(String deviceStateName) {
this.deviceStateName = deviceStateName;
}
}

public enum status {
