For the specific application of controlling the temperature of
dispensed water (eg in a shower), if you must have a fancy controller,
why not consider an in-line water heater?  The temperature control
problem then changes from one of moving a mechanical valve (ugh! moving
parts!) to one of simple multi-kilowatt power control,  which is
decidedly more up the alley of us sci.electronics types.

Unconventionally,
