Successfully Adding System Variables for Total Power Usage

I recently faced a challenge in my smart home setup where I wanted to monitor the total power consumption across three different lines (L1, L2, L3). Each line had its own system variable tracking the power usage, but I needed a way to combine these values into a single ‘Total Power’ variable for easier monitoring.

After some research and experimentation, I discovered that using a simple script within my home automation system allowed me to add these values together. Here’s how it worked:

  1. Identify the Variables: I located the three system variables (Leistung L1, Leistung L2, Leistung L3) that were already being updated with real-time power consumption data.
  2. Create a Script: I wrote a short script that reads the values of these three variables, sums them up, and then writes the result into a new variable (Leistung gesamt).
  3. Testing and Validation: I tested the script to ensure it accurately reflected the total power usage. It worked perfectly, giving me a clear overview of my energy consumption at any given time.

This solution not only simplified my monitoring process but also provided valuable insights into how I can optimize my energy usage. If anyone else is looking to achieve something similar, I’d be happy to share the script or provide guidance!
