Home Assistant Energy Dashboard With Vera/Z-Wave Sensors

Setting up the Home Assistant Energy Dashboard to work with power/energy sensors on a Vera Z-Wave controller.

Timeline:
00:00 Introduction
01:40 Vera controller
02:54 Energy Configuration
03:40 Z-Wave Sensor Details
04:34 Vera Integration
04:55 Template Section
06:35 Recorder
06:50 Statistics and Integration Section
08:25 Utility Meter Section
09:25 Create an Appliance Energy Sensor
11:50 Restarting HA Core
12:15 Adding new Device Energy Sensor
13:16 Refrigerator Energy Consumption Data

It doesn't seem possible to directly connect Z-Wave sensors, like the Aeotec Home Energy Monitor or smart switches and dimmers into this new Energy Dashboard.

It's necessary to use the template feature to pull power data from the desired Vera sensor into Home Assistant. Then make use of the recorder, statistics and integration platforms to create HA compatible energy sensors for the desired Z-Wave sensors. Finally, add those energy sensors to the utility_meter section of the configuration.yaml file, see example below:

Once you set up these sensors, they can be used to populate the new Energy Dashboard, which was included as of 2021.8.4 version of HA.

I didn't find much Vera or Z-Wave specific information on doing any of this on-line. I wanted to document how to bring this data in and give a few examples of how to do it specifically. I found the the HA documentation is very generic and gives examples like this:
# Example configuration.yaml entry
utility_meter:
energy:
source: sensor.energy_in_kwh
cycle: monthly
But nowhere does it say where this "sensor.energy_in_kwh" comes from, etc.

More to come...
