Poor software and customer support
Customer support is nonsense, it takes them a week to respond with something trivial.
Bad long term support - don’t buy
Great device
The app, notifications and Home Screen widgets work as expected on iOS. A good way to monitor your air quality.
One suggestion is, allow for decimal places when displaying temperature in the iOS widget. I assume most of your customers use Fahrenheit, so decimal places wouldn’t be that important. But if someone who has their device set to Celsius , having it round up from 24.5 to 25 in the widget is annoying.
Also I would have liked to buy your business product with sound DB monitoring. Living in an urban area with construction and noise pollution it would be great to get a notification to shut your window. Or with automation, close a smart window 🙃
