Notion Generation FAQ

Does my generation 2 Notion system still work if it is no longer for sale?

Yes! Your Notion system is unaffected and will continue to work and receive updates.

What does it mean to upgrade to generation 3?

To upgrade your system all you need to do is add a 3rd generation bridge to your system by purchasing a bridge or starter kit. That way your system can continue to support your existing sensors and you can grow your system with 3rd generation sensors. Your Notion app will display and send monitoring alerts for all generations.

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
