Harmoni Radiator

Hi I am new to Home Assistant and am getting setup generally. I have it running and sucessfulyl pulling in information from smart plugs, a GIveEnergy Invertor and battery setup, a Myenergi Car charger and my solar pannels. All great so far.
I also have an electric radiator by Harmoni heating (NOT a Harmony device), which is wifi controlled with energy monitoring as well as temp etc, which I would like to add to monitor the energy usage through the winter. Although I could just add another smart plug to the system I wanted to see if I could add the information direct as I would get more information and well make use of what’s there already.

Hope you might be able to help
Thanks

Update, I contacted the manufacturer, who has said “The harmoni app can be controlled via Amazon Alexa Home assistant. It is not compatible with any others I’m afraid” - Is it possible to get the readings to home assistant from Alexa home assistant?
