Low power consumption, setup and sensor variety
Overall, a very good product that consumes little power and data (400-800 MB per month). Setup is easy, and there's a wide range of sensors. Remote control is even possible.
The downside is that you can't connect to the Wi-Fi in some marinas – specifically, when the Wi-Fi requires manual confirmation of the connection (captive portal). Furthermore, it can only connect to 2.4 GHz Wi-Fi networks, not 5 GHz. It took me a while to figure this out. This should be more clearly stated in the manual and ideally changed.
