This Z Wave device comes in handy for a number of reasons - I have a couple and I am going to be ordering a couple more.
First of all it is a basic Z Wave, on and off switch. Where it really shines - it's an energy monitor, and can show stats for amps, volts, kWh and watts used.
I have one connected to my washer and dryer and use them to send an alert when the cycle is done (when the watts drops off to zero, it triggers the alert)
This is about $10 cheaper than the current price on Amazon. They are also having a Labor Day sale
I have attached a pic showing what is displayed from this device using Homeseer as the hub
