Electricity price and usage costs - OpenEPaperLink/Home_Assistant_Integration GitHub Wiki

This shows price, cost and electricity usage:

What you need:

• Nordpool (or other source of electricity prices)
• A sensor that contains electricity usage so far today, read from the meter (e.g HAN-port)
• A sensor that contains electricity costs so far today
• A sensor that contains electricity usage so far this month

Notes:

• All numbers are rounded to not show decimals. If you want to show decimals, please change the "round(0)" to your liking.
• The time format for last update is "HH:MM". To change this, replace timestamp_custom('%H:%M') with different format
• Please do a search&replace for all occurences of the default sensors with your own sensors
• Take a look at the "color"-settings of the numbers and update the value you consider to be "high", which is uses to show the numbers in red color
