I had an interesting alert on my Cerbo GX running firmware 3.75 - Gray Water Tank Low Battery with an old timestamp even though my Gray Water Tank sensor is a resistive sensor without a battery.
The correct alert and level is displayed when I remote view the Cerbo via my web browser, but the wrong alert is displayed on the Cerbo GX screen still.
The other alerts and timestamps don’t exactly match either when viewed on the GX Touch 50 vs the web browser.
I also discovered that the UI displayed on the GX Touch 50 is now malfunctioning - trying to go to Settings->General or any other menu just re-displays the Settings menu again. The menus work correctly when viewed via the web browser, and after I reboot the Cerbo GX via the web browser.
First the erroneous Gray Water Tank sensor battery low alert on the GX Touch 50 connected to the Cerbo GX:
Then searching through the sensors and found the low battery on a Ruuvi sensor:
The alert displayed in my web browser connected to the Cerbo GX is correct and shows Ruuvi sensor battery being low with a more recent timestamp, instead of the erroneous Gray Water Tank battery low alert:
