Buffered Data and idea for Failover

[muebau]

Hello,
as the ship is connected to the WiFi of the harbor I send all the data from OpenPlotter to my Server.

It would be nice to buffer the data if the ship has no Internet connection and send it as one bulk transfer to the server if back in the harbor.

Data:

• some NMEA0183 streams (mainly AIS)
  
• data from BME280
  
• several Zigbee sensors
  

The other thing is that the raspberry pi 'get lost' sometimes and I cant reach it anymore until I restart everything by power it off and on again.

I try to prevent this with a daily cronjob now:

Code:

0 3 * * * /sbin/shutdown -r now

Does somebody have a better solution?
Is there a better way to solve this "remote and offline at some times" problem?
