I’m only getting readings of 300 from my CT clamps. Is there something i need to change?

Looking at your screenshot, it looks like it is actually the temperature inputs that are showing 300. This would mean that no temperature sensor is present.

There’s a reference list here:

Input list of an EmonTx

Welcome to the OEM forum. You would need to look at the sketch for the emonTx V3.4 to find out what the items are. The list is: Message count (ulong) Line Voltage (V × 100) (int) Power 1 (W) int) Power 2 (W) (int) Power 3 (W) (int) Power 4 (W) (int) Energy 1 (Wh) (long) Energy 2 (Wh) (long) Energy 3 (Wh) (long) Energy 4 (Wh) (long) Temperature 1 (deg C × 100) (int) Temperature 2 (deg C × 100) (int) Temperature 3 (deg C × 100) (int) Pulse Count (pulses) (ulong) int = signed integer (2 bytes) …
