Updated 2023-07-12 ! There are some Node-Red nodes, (NRN), that are dependent on the old Noble package which don't work on Node > v8.  One nice and simple NRN is the  node-red-contrib-noble  which have the same problem. I picked up the freshest source, dependent on  @abandonware/noble , forked it and added install instructions. It works with Node <= v18. 

The use case was that we on our yacht have a security alarm which is using 2 G, service terminating during 2024 ?, so it was time to check for some other solution.  Since several years we have used the very nice  Teltonika RUT 240 (TR) onboard which have served us very well. Knowing that this device have both a digital in and out I started to check if it could do the job ??  Googling didn't give any direct clues but the " Input/Output " handling together with " Profiles " changed with a SMS, " Mobile Utilities ", is doing the job. Please note that this setup could be done with any of the routers from Teltonika with I/O !!
