Concept Temperature Map

This is something that I've wanted to play with for a while. The concept is to display a visual representation of things like temperature or humidity to understand the relationship of these values across the entire house. The color map is set to 50ºF to 80ºF for these images, so the apparently "hot" attic is actually 75ºF here. A couple of you have seen them already...

I also have a "planar" view of the same data that makes it easier to see the relationship of interior rooms.

There are some slight differences in scale between the two images beyond the obvious--that have more to do with ensuring that each plot is displayed proportionately. For giggles, I've also thrown up an animated version of the first one.

While we would probably never use it this way, the plot could also be used to show occupancy (I've included a point in the basement to demonstrate one way to do that, and the script could be easily adapted to change the color of an entire room to display occupancy). The first plot shows one way to do that. This isn't something that could be easily adapted to a plugin because the representation of our home is hard coded into the script. In other words, the script would need to be individually adapted to another house by hand.

I do plan to share the scripts on GitHub once they're in better shape if folks want to fork them (they're not even tied directly to Indigo yet) but wanted to throw these out there to get folks' reaction in a blatant attempt to get good ideas for nothing.

Everyone Else: "Hey, maybe we could get a variable to update with room occupancy"
Dave: "I've seen Star Trek, hold my beer..."

My wife might want to ask the computer where I am so that she can avoid me. Wouldn't want that!

Hahahahahahahaha.

Very cool Dave.

If you build your house out of transparent aluminum she could always see you.

It'd take years just to figure out the dynamics of that matrix.

Scotty can help.

I've uploaded sample scripts to GitHub. They use Python 3 so they aren't suited to run directly in Indigo. In other words, they need to be called some other means with the data passed as a parameter to the script. Given the relative complexity of the scripts, they require at least a moderate knowledge of Python to implement. You'll need to install Python 3, ffmpeg (or another compatible video encoder), add a vehicle to transport the data, and modify the map (unless you want a map of my house). I'm happy to answer any questions about the scripts themselves, but I can't commit to helping with the intricacies of all the mods that are needed to use them.

Amazing and thank you for sharing! I finally have a fleet of esp32 motion/temp sensors ready to deploy (after my gutted house is rebuilt) and this looks great for it.

My pleasure. Please share when the time comes if you are comfortable doing that. I would love to see what you do with it.

Of COURSE I will.

To me, this is one of the most critical parts of home automation and energy savings. I love the idea of visualizing the temperatures in different rooms and how they relate with each other and the main HVAC system. The fact that I love that probably makes me a gigantic nerd who should have been an engineer in a different life.

I am also honored to be your first Youtube subscriber.

Sweet. I know you share a lot, but I didn't want to presume.
