The SmartShunt is a great idea but the current version has some weak points. Things that would make this product awesome would be:
1. Improved IP rating: The current version is only IP21 so not suited to any external install without an additional enclosure. Making an IP65 version would be great for under-bonnet or installs that are somewhat open to the elements, even if it meant not having direct access to the VE.Direct port.
2. Better Bluetooth Antenna: The Bluetooth antenna in the current SmartShunt is woeful. When installed inside an enclosure you're lucky to get 5m of range. This really needs to be improved.
3. Data logging: The current implementation of the Victron Connect app only graphs live data from the SmartShunt so to see the graph you need to keep the app open. It would be much more useful if the SmartShunt could log the data and then the VC app can download and display it, even if it's only the last hour or so.
