There are many different ways to do this, but As long as you are either arming the smart home monitor or setting a mode to away, you can use smart home monitor, and that will probably do the simplest. Just create a custom alert based on temperature on a particular sensor.
- Open the smart things mobile app to the dashboard. Tap On the “smart home monitor.”
This will open the smart home monitor status screen.
Two) click on the 3 vertical dots in the top right and choose Configure to create a new notification.
Three) choose custom
- now you can choose to trigger off of “temperature,” then choose the sensor and the other parameters.
- define the kind of notifications you want to receive, and when you want to receive them. You can use the “more options” to restrict them by mode so you only get it when you are away.
- give it a custom name, and save it.
Just remember that these notifications will only occur when you have “armed” smart home monitor. That sounded OK for your use case, but just in case you want to do it some other way, you can look at the apps in the marketplace and choose one of the notification ones there.
