Where to start. It's 4 am in the morning and heating had come on again. This system is costing me thousands. Nothing about it is smart, have to hunt through ui to turn off anything and everything that is smart or faux ai. Seemly impossible for me to have the heating and hot water on a timer without it coming on at night for no reason and waking my children and wife. About once a month we'd loose connectivity to the heat sink unit, takes up to an hour turning the gadgets on, off, on, off etc...
