Cerbo GX Tank values freeze

I have tree tanks monitored by my Cerbo GX. 2 having normal resistive senders one being a Gobuis. This worked perfectly last year. After updating to v3.00 the measurement seems to to just stop/freeze. There are values (old) and status is OK. Unplugging the connector with the wires to the senders do nothing, status still OK.

The resistance of the senders on the connector yields correct result (e.g senders and wires are correct)

After a reboot, the Cerbo now reads the correct data. Unplugging the connector and the Cerbo says “Disconnected” on status (which is correct)


So, it seems that the process or function measuring the tanks crashes or freeze up.

Running VenuOS v3.00 large with SignalK enabled.


Anyone having the same issue and what is the resolution?

Try a rollback to the previous firmware, to check if that's actually the cause.

For reference. Data from VRM showing the level goes flat even if we used water throughout the 19:th. Tank filled noon-ish 17:thimg-8157.jpeg

Running longer the problem with the values freezed appeared again. Upgrading to 3.01 had no effect. After running for a few days, the values get stuck and don’t change when the fluid level changes in the tanks (2 resistive, one Gobius (updated and connected as per instructions).

Other functionality of the Cerbo works normally.

A reboot fixes the issue until it locks up again.
