is it possible?

Id like my OpenPlotter RPi to send packets of data when my boat is unattended. Things like battery voltages, bilge switch status etc etc.
I currently do that using an on-board MiFi router and a GSM connection which works OK but Id like to reduce the traffic down to Kb rather than Mb
I'd like to setup a NB-IoT connection so I was wondering if anyone else had played with NB-IoT SIMS and devices ?
Thanks

This can be done pretty effectively and affordable with zigbee devices, or with any I2C or UART attached sensor via signalK.  I use both, just cuz zigbee is so convenient, but the types of sensors are super limited, but both can be used and so long as the data is sent via a protocol signalK can parse, the output can be send via node red logic and a cloud based alerting system, or via remote access to a local signalK server on the boat. I have maybe 5 zigbee sensors deployed (for things like water detection and motion sensors) and the rest of the monitoring I do is with any number of cheap but high quality sensors via  NMEA to signalK, that's the single source of truth for all data and I use the off-the-shelf (or plug in) functionality of that as much as possible.   The instrument panel can be accessed anywhere, if set up for that, and if you don't want to keep starlink running all the time, you could write alert logic that powers starling with a zigbee smart plug, wait for the network to connect, then send and de-power starlink.  All you would need for that is a zigbee smart plug (if starlink is powered via AC, if not a smart relay could be used), and the rest can be done on that platform with just a couple plugins.

I hope that make sense.  There are other ways to do this, but this a basically my approach and i've been happy with the results.
