Cerbo gx mk2
After installing v3.70~24 both diesel tank and black water is missing from devices and overview.
Fresh water is still present.
After 2 reboots, they are back 
Hey @Slapperia good that they’re back but not good that reboots were required. If it happens again, can you leave it in that state? Would be great if one of us can login (using the feature in Settings → General → Remote Support) to hopefully find the cause for this.
Will do
Morning Matthijs, my two water tank monitors disappeared in the night, do you want to remotely check what’s happening before I go for a reboot?
yes!
Okay it fixed itself after 16 hours out?
That happened to me too. It did not take 16h but after a reboot sometimes it takes a little time before tanks appear again
Was Something found? Is it a bug? We have a customer experiencing the same problem on 3.64 (started on 3.62 and update did not solve the problem.)
Multiple reboots did not help either.
