I would like to be able to remotely switch on/off water heater/tank that runs on 240V. I usually turn it off using the circuit breaker. As a plus it would be nice to see the power usage, just like on the smart plug.
Not sure if it's readily available yet, but this should take care of the switching. I don't think it will do energy monitoring though.
Edit to add: It says that it supports energy monitoring in the description and it shows to be available for shipping on the Lowes website.
You could pickup one of these and use a SmartPlug to trigger it on/off, you won't get energy monitoring out of the 220volt load though.
Yes i have the remote which i have got after ac installation. You won't have to move from your bed and you can turn on and off your ac unit.
