I have a smartshunt attached to the battery of our camper trailer. The first few weeks connectivity was fine, and since then it has been terrible. This is the second time I've been unable to connect via bluetooth, standing right next to the battery and smartshunt (maybe 1 foot away with no metal objects in between). I guess I can un-pair it and re-pair it again, but if I have to continue doing this every time I want to see what is going on with my battery it is going to get old really fast. Any ideas or tips would be much appreciated. I know these devices get very good ratings, but so far my experience has not been good. Thanks.
