I’ve got a Cerbo Mk2 on my boat using the tank level inputs. I’m facing sporadic wrong %-values for my water tank. The sensor is 0-190Ohm and currently showing a reading of 31Ohm. This should be 16%ish. That value was shown for a couple of days, but then it’s drifting off. Currently it is still reading 31 Ohm but 63% of tank level. That is way off.
Sometime I fill up the tank, the value is rising up to 92% an then it stops while the resistance is already at 191Ohm, so should be clearly 100%.
I have attached two screenshot showing my current state. 31 Ohm reading, 0-190 Ohm configuration and a % reading of falsely 63%.
Firmware is 3.66, so the latest (but this bug has been there for the last couple of releases as well), there is no custom shape etc. configured. I tried input 1 and 4 with same bug, changed the instance and checked the connections. After a reboot the % is back on track at 16% for the next couple of days, but starting to get off and buggy again.
Is my cerbo faulty or is it a bug? Is this already known and is there a workaround?
