Optimizing Heating Profiles with Switch State Visualization in OH3

Hi everyone,

I wanted to share my experience with visualizing switch states over time in OpenHAB 3, which has been incredibly helpful for optimizing our heating system. As many of you might know, I’ve been working on a project to track the valve states of different rooms to better understand and improve our heating profiles.

Initially, I wasn’t sure how to approach visualizing 14 binary states simultaneously. After some research and experimentation, I stumbled upon the perfect solution using OpenHAB’s built-in capabilities. I decided to use the Graph Widget in combination with Transformation Patterns to map the binary states into a more digestible format.

Here’s how I set it up:

  1. Data Collection: I created a custom transformation pattern that converts each switch state into a numerical value (0 for off, 1 for on). This allows the Graph Widget to interpret the data correctly.
  2. Widget Configuration: I configured the Graph Widget to pull data from all 14 switches, each represented by a different color for easy differentiation.
  3. Visualization: The result is a dynamic graph that shows the state of each valve over time. This has been invaluable for identifying patterns and inefficiencies in our heating schedule.

One unexpected benefit was how this visualization helped me communicate the need for adjustments to my family. They could see, in real-time, how the valves were operating and why certain changes were necessary.

If anyone is looking to implement something similar, I’d be happy to share my transformation patterns and widget configurations. It’s a fantastic way to gain insights into your home’s energy usage and optimize your systems for maximum efficiency.

Happy automating!
