I use a pair of Veratron J1939 <> N2K engine gateways to get RPM and engine run time information into my N2K network. That hardware will send tank information from each engine control panel to N2K as well, even though those inputs on the engine are not connected to a tank level sensor (they are already on the N2K bus with a Yacht Devices Tank Adapter). This results in 4 fuel tanks being displayed on my Cerbo GX, though two are empty. These get consolidated into an overall fuel level, so without clicking into the consolidated view, I can’t see the individual values.
Please consider adding a feature where these extra tank sensors can be “removed” or “ignored”. They are currently sending N2K values of “Null”, so I feel like this should just be an automatic filtering. Here is the N2K message as it comes across N2K:
