Well.. My initial use is for a pool temperature / level sensor.. The temp is easy - It's registering as a V_TEMP and working great, but what I want is for the level to say "1.5 inches low" or "2 inches high", etc.. I currently have the value implemented as another V_TEMP, and have my arduino code calibrating the code to show 0 degrees if it's "perfect" and then plus/minus one degree for each inch the pool is high or low, but to have a sensor that is named "Pool level" and the data being "1.5 degrees F" isn't intuitive. I thought about using a distance sensor, but I couldn't get the distance code to work in the first place, and then I'd have to just remember what "distance" is normal (ie: is 0 the "top" of the pool, the the distance represents how far down the water is?) It just seems simpler in many cases to have a few english words displayed in the Vera website.
Another idea I have is to replace all my "expensive" z-wave door sensors with MySensors on Pro Mini because I hate that the output of the door sensor is just a picture of the door sensor with the "rainbow" on top either colored red, or not, and I have to remember which color is "open". I'd rather have a Vera output that just says "OPEN" or "CLOSED" and I can't figure out any way to do that with the regular sensors so I was just going to build my own..
I'm sure I'll think of more, but that's enough to keep me busy for a while!
.. didn't get to try any of this last night as I had hoped.. we ended up going to the town carnival instead... Will try again tonight!
