Puck.js case for electricity monitoring

I wanted to track my electric usage in real-time, and I’ve already have Home Assistant as my main smart home management system, so I wanted to make use of the Energy tracking feature that it provides.

Because my meter is located outside our house, I had to find a solution that runs on batteries.

I was looking into the Frient electricity meter, but couldn’t find any available anywhere. So I searched and found this DIY smart meter https://www.espruino.com/Smart+Meter

And to prolong the battery-life, I’m using 2 x D batteries instead of the small CR2032 battery.
