Can I use Briiv without WiFi?

Briiv and Briiv 2 works both with or without a WiFi connection. 

Units feature touch control buttons, so you don’t have to have them connected to the internet in order for them to work. You can still control the speed, and set the air quality monitor on a Briiv 2 Pro, using the touch interface.

If you don’t connect to WiFi you won’t be able to control Briiv via the app, and for a Briiv 2 Pro you'll be unable to amend the automatic activation air quality intervals, or use Zone Mode.
