Review on Stay Alert and Connected with First Alert GLOCO-500 WiFi Environment Monitor - Battery Backup Included by Ricardo Fast

This device is quite expensive for its features. It basically gives you temperature, humidity, and carbon dioxide readings, but it only works if you're connected to the same network as the device. Also, the app is poorly designed, it took forever for the device to connect to the app and then disconnected again after a few days, so I ended up using my Home app on the iPhone to get the readings . Something you can hook up to carbon dioxide and a room thermometer might work just as well as this expensive device. I was hoping to get room status notifications when I'm out, but that doesn't work.
