Zigbee + Energy Dash + Individual Devices not reporting correctly

Hi All,
I’m new here so hopefully this is an easy answer.
I’ve added my Innr smart plugs to the Energy Dash as individual devices. This worked for a 1-2 hours and then disappeared, all I see now is untracked consumption. When they did report in they were displaying kWh and not w.

Q- What am I doing wrong?
Q - Do I need MQTT or ZigbeeMGTT?
Q - Helpers?

Any answers, guidance and previous posts gratefully received.
Many thanks in advance.
