Just about any decent broadcast-oriented remote control system will do what
you want. For examples:
www.sinesystems.com - model RFC1/B (bare bones system)
www.burk.com - ARC-16, GSC3000, VRC2500
www.broadcasttools.com - several different units; look at their upcoming
VMC-8 product
The ProTek series from PageTek (www.pagetek.net) is pretty popular for
non-broadcast telecom sites. Their basic Jr. model may be all you need.
Keep in mind that you have to provide the sensory inputs to most of these
remote control/telemetry units. Most manufacturers sell temperature
sensors/probes, AC voltage sensors (which you can mimic just as easily with
an unregulated DC wall wart and some additional protection), etc., but for
something like fuel level, you'd need a sending unit in your diesel tank or
a pressure transducer for LP to provide a varying DC voltage to feed to the
unit.
Most will work with 4-wire links (or RF equivalent) that will pass FSK modem
tones (Bell 103), or you can go with outboard modems for higher data rates,
or IP connectivity if it's available for some of the higher-end models.
Most also support some form of dial-up remote control (DTMF control, with a
voice synthesizer for telemetry readback). Not all of them are capable of
multi-drop (parallel) communications however. See the manuals on the
respective web sites for details.

Subject: [Repeater-Builder] Remote monitoring of repeater site
Hello learned group members.
Does anyone know anybody that has a remote site monitoring system, ie
battery state, vswr, entry, generator start, fuel level etc.
I have a site in Africa that has 3 remotes site that we need to monitor
localing and if possible on a dial up modem from here in Australia.it will
need to leap frog thru a parallel telemetry rf link.
I can be contacted direct or thru the group. There was a system that I saw
many years ago but the memory is not that good to go back to a flyer some
15/20 years ago. I need a solution asap. Cheers.
