Offline Data logging within ctrlX and save in uSD card

Hi Mr_Wonder_Why , 

you got multiple options to store the data on the ctrlX CORE (or better on a μSD connected to ctrlX CORE). 

1. You can log your data to a csv file on a μSD. 
   • This post in the forum might help you a bit: Node-Red Datalayer to CSV on USB
2. You can use a Data Base App from the ctrlX Store (InfluxDB) 
   
   • ctrlX AUTOMATION - InfluxDB App in the ctrlX Store 
   • How to to get started with the InfluxDB App and Node Red (+Grafana App): IIoT: Use ctrlX CORE as a monitoring platform using InfluxDB and Grafana
3. You can build your own Data Base App (for example including an open source data base)
   • One example: Mongo DB in ctrlX OS 
   • Second example: PostgreSQL on ctrlX CORE

To send the data over the network to some database (like you did with your laptop) is also possible. 

Best regards, 

Nick
