Hi

I am reading data from a CSV file and shipping it into influx.  
I have made a flow that is working, it's a bit ruff and I could use some help finishen up.

My flow looks like this.

 ![Udklip](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/e/7/e7e6aee2ad175aa1e413ef2dc9d9fd04361e9f3f.png)

My problem is that this setup is needed for every type of unit I have making a CSV file.  
My CSV file looks like this.

```auto
200923224515	654216315	Serial-number	Firmware-Number	1	46	-61	89450100170913022654	382	14	0

200923214603	167.101	247.755	0	0	0	0	0.05	0.001	8.051000	19.280001	0	0	0	0	0	0	0	0	3.86	0	0	0	0
200923214703	166.648	247.56	0	0	0	0	0.036	0.001	8.061000	19.280001	0	0	0	0	0	0	0	0	3.86	0	0	0	0

```

The serial number is the units name, but depending on the firmware-number, the data I need to read is different, so after the long explanation, my question is as follows.

Is there a way to make a setup, so it is read the data depending on what the firmware number is?  
And happy new year to all 🙂

Read the data in and after the `file.in` node, put a `switch` node.

Use the `msg.firmware` field to route the message.

If you don't understand this, put a `debug` node just after the `file.in` node and show the entire message.

Hope that helps.

Thanks a lot, that was it and a simple one as well 🙂
