To manage multiple properties in a single App, simply launch your Sonic mobile App and then tap "Home". At the top of the screen the name of your property will be displayed (next to the bell icon). If you pull don on it, an option to "set-up a new property" will show up.
From here, you can also view different properties that are linked to your Sonic mobile App.
Once you have filled in the property name and address, you should be able to add rooms and appliances on the property. After this, please follow the guided instructions to connect your Sonic to the property.
If you have any questions, please feel free to reach out to us.
