Shelly EM Energy Display - Configuration - Home Assistant Community

I have recently purchased a Shelly EM which I have fitted successfully into our fuse box with one transformer coil on the main feed into the house. I have also installed the default Shelly integration and seeing 5 sensors (as below). In addition, I have also built a number of other sensors for voltage, amps etc. However, I cannot seem to add any of the sensors into Energy configuration (see error below). Any suggestions please as ultimately I’d like to see how much energy is being consumed
