Nuki iOS App
Low battery warnings are only shown within the app on the top right bell symbol. To see this warning, you need to open the app what I hardly ever do since I’m using the Auto Unlock and ring-to-Open features.
To make sure I am not missing the low battery warning, a standard iOS message should pop up to make sure I am not missing this extremely important warning. If I miss it, I’d find myself locked out as I totally rely on Nuki and don’t carry a key with me any longer.
A persistent iOS message that makes sure I am receiving the warning to replace batteries. This message should pop up not only once but at an increased frequency the lower the battery gets.
To make sure I am not locked out of my place with no battery left in the Opener or Lock and no means of opening the doors manually. So, for a mission critical reason.
