Serial output from energy monitor into HA raspberry pi

Hi

I’m trying to get serial data from this energy monitor to work in HA, I have tested and can read the output using raspbian, but on my pi4 I am using the HA os

http://lechacal.com/wiki/index.php?title=RPICT3V1

It outputs like this:

"pi@raspberrypi:~ $ cat /dev/ttyAMA0

11 2.94 12.55 0.05 244.34 0.159 1.20 8.29 0.03 244.20 0.121 16.25 30.73 0.13 244.31 0.521"

Which according to the documentation is:

NodeID Realpower1 ApparentPower1 Irms1 Vrms1 PowerFactor1 Realpower2 ApparentPower2 Irms2 Vrms2 PowerFactor2 Realpower3 ApparentPower3 Irms3 Vrms3 PowerFactor3

my yaml config looks like this:

If I enter

{{ states(‘sensor.serial_sensor’) }}

Into developer tools - template, I get:

Result type: string

unknown

Any help would be much appreciated!

Thanks
