Isn’t there a physical limit to solving this problem? For me the problem is typically, that the water in the hot pipe has cooled down, so the first few seconds/half a minute it slowly rises in temperature until finally the pump of the boiler sets in to pump actually hot water back into the system. Only then can I reliably find a temperature mix that stays stable.
Japanese showers for the win: temperature is written right there on the nob for many.

Mine is digital. Just set to desired temp and power and away you go.
