Connection via home router hard to set up and now only works intermittently. Need to do the programming of my Sofa on the rare occasions the app sees the furniture. Connection via the furniture broadcasting its own gateway is only slightly more reliable. Once running the app is not intuitive. Did not realise initially that the graphic which appears allows one to select different seats. All seats in the same sofa count as ONE device and have only one IP address and MAC. This was not made clear in setup. App keeps crashing.
Some crashes on older Android devices corrected
