Amazon calculates a product’s star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
I can discover the tilt sensor but the device reverts to searching for networks and no sensor data is received at my gateway (Conbee II). Have tried restarting gateway, factory resetting sensor and pressing the push-button 4 times on multiple occasions with no luck. I emailed the vendor late last week and will return the sensor if I don't hear back with a solution in the next couple of days.
