Paul -

Thanks! I see it now. I was thinking the datacode(s) setting was specific to each individual part of the payload that I was sending and that it just had to match what was being sent.

I did try

```
datacodes = f, i

```

Which matched what I was sending, but that gave me this:

```
2016-06-26 02:02:36,644 WARNING RFM2Pi 449 RX data length: 6 is not valid for datacodes ['f', 'i']

```

Why is that? It should ahve matched the two fields I was sending it (temp and psi) and 6 should be valid for ‘f’, ‘i’ based on what you are saying.

Thanks
