Hi I have 5500SHAC which looses changes after a reboot. If I add new object or make changes to Visualizations they initially appear to web browser client, however if the 5500SHAC is rebooted, all changes are lost. Also looking back at my trend logs these seem to have stopped recording information several months ago too (older data is still shown on the trend graphs however). System Status looks ok to me (one: it doesn't look like the system has run out of memory etc). I have a number of scripts which update time, household temperatures and weather info to User Parameters at regular intervals - these still seem to update ok. Is there a system setting to take the unit out of read-only mode or is the 5500SHAC susceptible to memory failure over time and needs to be replace? This unit has been running since late 2017. Any pointers on how to resolve this would be greatly appreciated.
