Yes! While there is not a specific way in the Notion app to dedicate different sensors to different locations, it is absolutely possible to install sensors wherever you would like as long as there is a bridge set up within a reasonable range.
To set up a second bridge, click the sensor icon to get to your hardware settings and click the bridges tab. Then click where it says "add new bridge". Once your new bridge is set up, then you can install any number of sensors you would like. Again, click the sensor icon and go to the sensors tab. Then at the bottom, click "add new sensor" and go through the installation process. When you name your sensors, make sure you use a custom name that will allow you to know which sensors are in which location. For example, we have had some users use the title "Breck front door" for their system in Breckenridge, Colorado and then "ATL front door" for their system in Atlanta, Georgia.
Be aware, when you have multiple systems set up in multiple locations the notification preferences for home and away mode does not always work. This is because the Notion app will only let you set one location as your home location. In most cases we suggest that users turn on all alerts for all of their sensors when they set up Notion in multiple locations. This way you wont miss any important information from your Notion system!
Our developers are working on big changes for Notion that will allow you to set two separate locations as home so that you can continue to customize your alerts for your primary home and your vacation home.
