I am simply trying to get a (push or text) notification when it is warmer outside than inside, according to my own sensors.
I thought that this would be really easy to implement in SmartThings, but so far I have been unable to figure it out…maybe someone has already filled this niche.
I have a shaded temperature/motion sensor on my front porch that gives a very good outside temperature reading, and I have several interior temperature sensors to choose from. I am in Colorado, so it is cool and dry at night in the summer, and we frequently leave the house open in the morning to cool off.
But it does warm up during the day, so I would like to be notified when the outside temperature crosses the inside temperature so that I can close up. I frequently get absorbed in my work in the home office, and when I look up it’s 80 degrees outside and I have sacrificed a bunch of my cool air for the day.
I have considered a couple of approaches:
- Notify me When: This will give me a notification when a sensor crosses a set point. That’s not bad, but what I really want to know is that it’s now 67 outside and 66 inside. That’s when I would close the windows. If I pick a set point like 72 degrees, the outside air will be warming my house until 72 hits.
- Whole House Fan: There is an app to trigger a fan/switch when it is cooler outside than in. Of course, I don’t want to trigger anything, but it occurred to me that I could create a virtual switch that this app could move, and then elsewhere I could send a notification when this switch went from off to on, or something. But alas, I can’t figure out how to do that second part…Notify me When won’t monitor switches, it seems.
But really it shouldn’t be this hard. I have searched around but things often slip through the net…can anyone point me to a simple temperature comparison/notification app?
(Additional nice-to-haves: mode selector, so I’m not getting notifications when I’m Away, etc; bias field so that I can calibrate the comparison)
