Our Cerbo runs large image with NR script. As the Multis only contain inaccurate grid frequency values, the NR script polls external ABB meter to get grid frequency 2 digits accurate behind comma, one value each second.
The NR grafic display works like expected, but after a few hours it slows down until it becomes unusable. Obviously, the reason is NR cannot handle the high amount of data properly without database. As far as I understand, the use of a time series database (TSDB) like InfluxDB could be a solution. At least using a high endurance video SD-card, memory should be sufficient to store the data.
Is this a feasable idea to install InfluxDB on the Cerbo or would you prefer running InfluxDB at a bigger external server? Are there already any readings on how to install InfluxDB at the Cerbo?
