After my mom was bed ridden for some time, I reluctantly installed some Alexa enabled smart bulbs and switches, so that my mom could operate it by voice commands. But I made sure that I created a separate wifi guest network with low bandwidth to ensure Alexa / smart appliances don't waste the bandwidth unnecessarily (even if they leak the wifi password).
