Appliance Energy Monitoring Using ZWave

Appliance Energy Monitoring using Z-Wave

Ever get an expensive power bill and want to know what appliance was the culprit? Maybe you want to learn how much an appliance is costing you? In today’s article, I show how you can use the Zooz Z-Wave Plus Power Switch with Home Assistant, InfluxDB and Grafana to track and plot an appliance’s energy usage and cost. The result is an easy to digest Grafana dashboard you can use to track what time of day your appliances are consuming the most energy and how much it’s costing you!

I’m using Z-Wave in this article, but feel free to substitute for whatever protocol your Home Automation setup is using. As long as you can get energy measurements for an appliance into Home Assistant you should be good to go!

Zooz Z-Wave Plus Power Switch Review and Setup

Ever wanted to be alerted when an appliance has been on for too long? What about switch a device on and off from your phone or through an automation? This is the perfect application for a smart switch! Today I’m going to be looking at the Zooz Z-Wave Plus Power Switch (ZEN15) and integrating it with Home Assistant with notifications.

There are a ton of smart home switches on Amazon. I have invested in a Z-Wave Plus mesh network in my house, so I went searching for a great Z-Wave Plus switch that measures energy usage. Z-Wave communication is all local so you don’t need to rely on any cloud service being up or any companies taking your data. It also works at a lower frequency band (908 MHz) than WiFi. So it won’t cause congestion on your 2.4 GHz wireless spectrum at your home that your WiFi and Bluetooth devices already use.

Add a Z-Wave+ Dimmer Switch to Home Assistant

Automating your lights are a great place to get started with Home Automation. In today’s article, I replaced a traditional light switch with a Z-Wave Plus dimmer switch (GE 14294). Using Home Assistant, my lights automatically dim when someone starts playing content on the Chromecast in my Living Room after sunset. We find it useful to have a very dim light on during the movie so that we can still get up without stepping on stuff and still be able to see what we’re eating.
