Notion Generation FAQ

Finding your system generation in the Notion app

You can see what generation each sensor and bridge you have installed by opening the Notion app.

Steps

Tap on System > Tap on Sensors or Bridges > Tap on the Sensor or Bridge you want to check. The hardware version is listed at the top of the screen.

How we protect your data

End-to-end encryption for over-the-wire transmissions

AES 256-bit encryption for all data transfers between the bridge and sensors (that's the same level of security as a bank vault)

OAuth 2.0 for client authentication (the same level of authentication that Facebook and Twitter use)

Third party security and penetration testing
