..bis I could configure the app properly. One should put the device in its home network (WLAN) in operation. It can not be added from the Treasure Day app, but must be coupled only via Bluetooth. Then the day will appear in the app. At home I do not want to be constantly reminded by a signal, of course, to have misplaced my day. The Bluetooth range is limited in dwellings but rather so that one is constantly paged by phone. One can home and / or office network for the alarms to mute via the mute function, but only if you are in the network concerned. The battery will last about 1 month. Why chose CR2016, I can not understand, CR2032 is only 1mm thick, the life would have tripled.
