IMPORTANT: Factory Reset wipes all information from Senstone, including your unsynced offline records, pairing information etc. We recommend to perform if it's not functioning properly and other steps from Troubleshooting do not help or if you're giving Senstone away to someone else.
To activate Factory Reset press and hold side button for 6 seconds. A purple central LED light and two smaller lights on 10 oclock will flash for approx. 2.5 minutes. When the reset is over Senstone is ready for use.
