Collection of Home Assistant python scripts

This is very much about experimenting with pyscript and calculating savings from solar

Requirements

• Home Assistant
• Hacs
• Pyscript
• Nordpool or similar electricity price sensor
• Purchased and sold electricity total energy sensors
• Solar panel total energy sensor

Usage

• Create the necessary input_number sensor in Home Assistant
• Update the read sensors with what your sensors are named as
• Copy the files to you Home Assistant config/pyscript/ folder
• You should now see your input_number sensors update at 2 minutes past each hour

Note

The scripts write to input number helpers that have to be created in Home Assistant before taking the scripts into use. I've not figured out a way to make them persist properly if created through pyscript. You will also need to create a template sensor for each input number if you want to use them in utility meters as utility meters can't use input numbers as input sensor.

UpdateSpotPriceSensors requires NordPool sensor.

Scripts

List of scripts and what they do

SolarSavings

• Calculates overall savings from having solar panels compared to not having solar panels.
• Calculates car charging costs and savings from having solar panels
• Calculates heat pump costs and savings from having solar panels

UpdateSpotPriceSensors

Creates an easy to use number that will range from 0 to 3 based on long term and short term electricity cost.

Todo

• Find a way to persist a sensor created in pyscript properly so input_number sensors are not needed
• Make read sensors configurable somehow so you don't have to edit the code if someone else wants to use the scripts
• Add more fun scripts :)
