Z-Wave Smart Energy Meter - 9.99....Really?

I am currently using this one by @johnconstantelo

The one below is one without the battery tile. I don’t recommend using this device on battery because it sleeps most of the time and doesn’t report very often to conserve battery. Occasionally, this HEM v1 will send out wildly fluctuating numbers (over hundred thousand watts) and this DH can be configured to ignore those. Below is what it looks like.
