My smartshunt is mounted close to the batteries and these are of course located not very central in my sailboat. When I am in the cabin in the front I really cant get any connection. I guess it will be difficult to do something about it, as this is limitation in the bluetooth stack. But it should might be a function which keep the latest view in the memory or buffer? Of cource with a timestamp so I can see it is not alive. Together with a background update in the app, then this would really be great. This thong should not be very hard to develop as many apps are doing background updating.
