Feasible yes, cost-effective, not really
What's your budget?
If you get a vital signs monitor from ebay, you can actually secure pressure sensors, pressure gauges, temperature sensors, gas sensors, flow valves, IR sensors, A/D converters, alarm indicators, and a high-resolution display screen. This way, you can install a fire alarm system, a water level indicator and controller, a water heater controller, a gas-leakage indicator system, and a temperature monitoring system. You can hook all the sensors to a central monitoring system which can be controlled either via a universal remote or SMS-based wireless control system.
If you want to be super high tech, get a shower cap:
and control your system via EEG signals.
