Save Money Now: Track Dynamic Energy Prices in Home Assistant

Описание: Energy prices are going through the roof these days. Some energy companies deliver dynamic energy prices so that the price of energy changes every hour. This way, you can turn on your appliances when the prices are low. I am going to show you in this tutorial how you can create a bar chart of the dynamic energy prices in Home Assistant so that you can monitor these prices and see when it's the best time to turn on appliances like your washing machine. And on top of that, you learn more about how to work with templates in Home Assistant.

⭐ You can download the code that I created for this video at: https://ko-fi.com/s/e937e90ca8 ⭐

The download file also contains some optimizations to the code that is shown in the video.

NOTE:
If you install Zonneplan, you have to enable the following entity to make this work: sensor.zonneplan_current_electricity_tariff
Go to Settings
Go to Devices and Services
Go to the entities tab
Search for Zonneplan
Click on Zonneplan current electricity tariff
Select Enable Entity

NOTE 2:
In some cases, the bar chart is not shown for some people. If you experience issues with the Apexchart card that does not show a graph, then change the following code in the template:

replace float by float(0)

NOTE 3:
If you did not fill in the VAT percentage in the integration, you can also choose to multiply the price with your VAT percentage in the template, and on top of that add additional costs. In that case, the formula would be something like this if your VAT is 21%:

{%- set ns.prices = ns.prices + [(hours.value * 1.21) + states('input_number.nordpool_additional_costs') | float] -%}

Special thanks to TheFes for tweaking the code so that it got smaller.
