FEATURES • Fill level and remaining volume in litres and percent • Alerts for critical fill levels • Weather forecast for the location of your system • Level height and device status for every system • All devices on one central dashboard • Device data, assignment and location at a glance • Light and dark mode For cisterns and rainwater systems with GRAF BlueLevel and for retention and infiltration systems with GRAF ARCOS.

Verdict
The clearest difference is update cadence: Graf IoT at monthly against Wireless Basic's every 3 months. Wireless Basic's advantage is device support (3 vs 1) and iOS requirement (14.2 vs 16.0). On price, ads and in-app purchases there is nothing between them.
