The new Smart Shunts IP65 (1 for 600Ah Service bank and 1 for 110Ah starter battery) work well through the Bluetooth App Android connection. However when connected by the Victron VE.Direct extension cable they lost connection n the Cerbo GX. In the VRM portal, they show in the Device list but lost contact 20 hours and 2 days ago. What is causing this? And how to reconnect?
