Like the latest update especially the export data feature.
I live beside a very busy road and I have my concerns about air quality as well as all the detergents and sprays we use indoors. Goodness knows what we are breathing in these days. I find the cair great for keeping an eye on air quality. Setup was easy enough and the app is intuitive. When it sends me an alert I can open the windows and watch it telling me how the air quality improves. I have it for a few weeks now and I think it is great value for money. Glad I bought one. Rory.
Added a feature where you can select a sensor in the Account Settings page to directly move to that sensor for users with multiple sensors
