Smart Immersion heater. Thermowatt

Does anyone know if I can read the current temprature and control this smart heater from thermowatt: TMEC Wi-Fi immersion heater | Water heating elements | Thermowatt EN

It will be interesting to be able to have smart features in homeassistant like showing the water tank temprature (or how many people can currently have bath) in the dashboard. Automation to change the heating temprature of the element per hour of the day(at 07:00 which is only 1 person for bath heat to 45 but at 18:00 heat to 60 etc.). AI can learn how long the heater takes to heat the water so when I say hot water at 45 at 07:00 it starts earlier to have the water ready at 07:00 (like nest heating).
Finally you can read if you are exporting electricity from solar panels and ask for the immersion heater to heat the hot water tank.

There is an app that does basic functionality so there should be a way to interface with the immersion heater.
