Home Assistant – Power Information Chart

I wanted to display my Electricity Price, Power Usage Hourly, Power Usage Daily and Power Usage Now in a column chart. 

All this because of new payment model i Norway where you pay according to Hourly Power Usage.

I decided to use custom:bar-card: https://github.com/custom-cards/bar-card

I downloaded some code from Home Assistant forum and Facebook group and added some tweaks of my own.

The code can be downloaded here:

Below is a Light Mode screenshot from my phone.

 

I added also a simple automation that warns me when Power Usage Hourly passes 8.5kWh

All this to achieve maximum hourly consumption below 10kWh, due to new payment model to Norwegian grid companies.

I will also add some automations that temporary turn off devices and slows down my EV’s charging speed.

More  about that is coming soo.
