GoControl has some Z-Wave glass break sensors:
First Alert has a Z-Wave Smoke/CO alarm which I have, though I linked with Ring Alarm which is monitored…
For the Window sensors, I have all crank style windows and the screens make it so that I could only use very small sensors that fit within the window casing. The “Mi” Zigbee sensors did the trick for me but they don’t play well with other Zigbee devices, so I needed to set them up on a separate Hubitat hub and add repeaters near each one. The end result is pretty good and I haven’t changed their batteries yet in over a year.
Illuminance sensors are practical to decide when to turn on lights or not.
I have very similar rules to what @sburke781 described. I also have rules that warn me if:
- A window is open and the % probability of rain is higher than 60%
- AC or Heat is on and a window is open
Another setup that i have is that in the summer, Hubitat will let me know when it would be advantageous for me to open or close my windows based on the inside vs the outside temperature (and humidity). It will figure out if the temperature is the same or higher outside than in and rising and recommend via Alexa and an app notification to close the windows. If the temperature is the same or lower outside and going down, it will notify me to open the windows. The message includes a list of the windows that are open.
