Best device for remote internet monitoring of OP2
#1
Hi folks
I am trying to decide on the best way to remotely monitor my OP2 system and the ESP8266's which are used as battery state senders 

(this is prompted by the loss of my entire house battery bank (600Ahr) as a result of a broken solar panel cable over winter !"£$ ...argh)

I don't need a remote VNC session to OP, I just want the ESP8266's and (optionally) the OP/Pi to be able to maintain a reliable connection to the internet to send out the signalK paths via MQTT every hour.


So, I'm looking for a device or solution that provides; 
  • Bi-directional, Low bandwidth Internet connection via GSM for MQTT data.
  • Assuming it uses a data SIM, it must not expire after 90 days as I may need to keep connected without intervention for up to 9 months
  • Must be able to roam in Europe. Specifically Greece
  • High performance isnt necessary. I dont want to use it for browsing on-board, just remote monitoring
  • The boat is likely to be stored ashore in an area with patchy (marina) WiFi coverage but probably reasonably good GSM (4G) coverage 

I was thinking of a simple stand-alone MiFi device but wondered if there is a more elegant solution, perhaps a GSM board connected directly to the Pi ?

Of course Im interested to hear if there are any developments for OP2 that might help me?

I'm also interested if anyone else is remote-monitoring their OP and if so how have you achieved low-cost but reliable internet connection on-board
Thanks
