I recently installed a Smart Shunt in the battery box in my Class A motorhome. The shunt worked fine until the first trip after which it was reporting crazy numbers and would not connect reliably to the app via bluetooth. The battery box is semi enclosed with several sections open for venting. I was driving in heavy rain and wondering if it got wet enough to cause the problems. I replaced the unit but need to some ideas to water proof the shunt. Doesn't look like Victron sells a waterproof box for this unit.
