"My Vivint security system uses Z-Wave, and these plugs are amazing. They were easy to add to my devices and have worked flawlessly. I use them for a variety of purposes including holiday lights, my red light therapy lamp, and a hard-to-reach ceiling light in my garage.I can control all of them remotely from my Vivint app and panel, which makes life so much easier. They are a little pricey, but in my opinion, well worth it for the quality and reliability. I’ve never had any issues pairing or maintaining the connection. Highly recommend these for anyone looking for durable, weather-resistant Z-Wave plugs.Highlights:• Pairs easily with Vivint Z-Wave systems• Works reliably for multiple applications• Remote control via Vivint app and panel• Strong, stable connection with no pairing issues• Weather-resistant and durable design• Great quality and performance despite a higher price"

I use this connected to my washer so that in my Hubitat home automation system, I can monitor the power the washer is using at any given time, to determine when my laundry load has completed. My washer is in the basement and I can't hear it so sometimes I forget and leave the laundry in there too long. Bad habit, but this is my way around it. I was even able to setup an Alexa notification with a script in Hubitat. BTW. Have another one setup on my dryer to do the same thing.idahoneko
