I learned from customer service the other day that Steel HR (not limited to, I guess) is not reconnecting to the phone after the watch has been out of Bluetooth range (which is about 10-15 feet). You have to manually enter the app on the phone to get the watch to reconnect to the phone. This means that if e.g. you charge your phone in the bedroom while the watch is in the kitchen or go to get something downstairs, the watch will disconnect and making the notification feature on watch useless - this is unacceptable.
Don't get me wrong, I understand that you have limited range on Bluetooth devices, but the watch must be able to reconnect once in range and definitely if a real time notification feature is offered. The following statement was from a customer service representant:
Please note that the watch automatically syncs in the background when certain conditions are met. These conditions are:
You have taken more than 1,000 steps since the last sync, followed by one minute with less than 50 steps
More than 6 hours have passed since the last sync took place (excluding sleep)
The daily objective for steps has been reached
It is important that you ensure that:
you have not disabled Bluetooth on your mobile device
you have not forced the Health Mate app closed
The watch and the mobile device to which it syncs are close to one another (within a few feet) when the conditions for automatic syncing are met
So Withings, please address this (tentatively tell the watch to automatically reconnect when the notifications feature is enabled within the app).
