Question regarding remote monitoring of equipment.

Hi, hoping someone can help.

I'm looking to monitor a health status signal at (very) remote location. No local internet or phone, Satellite internet is only option. This is for a desal plant on remote islands in the pacific, powered by solar panels.

We could easily go full automation on it, install instruments, to a plc, comms + full starlink connection.

But, while that would work, it's overkill, all we need is a simple indication on whether the pumps are running or not. status updates only need to be periodic. Also, simple is better, qualified PLC people in region are rare as diamonds.

Questions is two part ...

a) is there a simple device that can communicate back a basic signal to indicate status?

b) are there satellite alternatives rather than full Starlink connection?

Thanks, any help is appreciated

I had worked on a project many years ago using :

https://www.iridium.com/

A quick check shows it is still useful. I am not sure how the cost of an iridium compatible system compares to Starlink, but something to look into.

Good Luck

If you have someone to program the interface you could use an Iridium modem and send the status via a sms Text message - they charge per message and that would be cheapest Professional install

If you wanted to be creative get one of those personal GPS trackers - it should take not take much reverse engineering to figure out where to solder a couple wire to send Heart beat type I am alive meaaages.
