Real-Time monitoring and MQTT would be nice, and I am a fan of Node-Red but internet connection is an issue as I dont have reliable WiFi in the boatyard. In essence, its a battery low voltage alert that I need so maybe an OP driven SMS from a GSM Dongle would be better for me.
Its interesting exploring the options though.

So if you dont like my node red solution and want to save your power get an arduino pro mini + GSM module + something to measure the voltage like the ina219. Put it to deepsleep and wake it every hour to get the voltage. If its below a certain value let it send a message to you in form of a SMS, mail, what ever.
Google the key words there are many youtube videos regarding this topics. You can get the job done in less than 2h.

I now have lots of ideas but I think your first suggestion (Node Red, Huawei modem etc) is probably the route to pursue

When watching the data trough GSM i mesured 6MB/ 10 min.
I have 150MB limt for data. After the 150 MB habe been used the speed is reduced to 64kb/sec, but unlimited.
This is still fast enough to transmit node red data and even still pictures from the webcam.

In case you do not need any openplotter stuff just take this image... thats my question which tracer you use... needs some fast configuration but realy ready to use

this is live https://solaranzeige.de/user/demo.php from a motorboat in bremen 350Watt in total the panels https://solaranzeige.de/user/demo_weitere_daten.php

ican upload the raspberrian build was from planed for a later time to make an article for my blog. is tested with some chargers of different companies... but still no signal k integration...

i forgot its not mine and the code is open but no gpl and its commercial so i did not choose for this but good for learning proposals...
