I have been using a USB Bluetooth dongle for my Mopeka tank sensors for a few months and about 3 days ago it stopped working. I thought maybe the dongle went bad so I put a new one in and same issue. What I find is Cerbo sees the dongle for a few seconds and then stops. Seems like Cerbo is cutting power because the blue light on thr dongle also shuts off about the same time it disappeared in the display.
