Seems I can only post in the TWG section of the admin side of the forums... This should really be in the hardware or highsite planning sections.
Right, if anybody wants to invest in GSM Commanders or SMS Commanders for high sites, my company is a dealer of theirs. We get 25% off the list prices advertisted on the site:
We use these things for all sorts of things. For example, I can sit here and send an SMS saying "CTWUG OFF" and the radio connecting to Diabolix goes dead. The reverse is also true. "CTWUG ON" will power the unit up again.
These little guys have saved us thousands of Rands in fuel and time when routers and servers crash "over the hills and far away".
I use the simple SMS Commanders for sites with just one radio while the GSM Commanders (I now only buy the Advanced version and will be selling my "normal" ones on Gumtree during the year) are used for sites with multiple radios and / or servers.
The Advanced GSM Commander connects to their website, so instead of sending an SMS, I can enable or disable ports with the click of a mouse.
I mate the GSM and SMS Commanders to "Finder" 16A changeover relays from Electromechanica so there's no current draw on the built in relays and the external relays are only powered when the equipment's switched off.
These things work. I have no intention of making money out of selling them to the WUG and would be happy for people to collect kit directly from the GSM Commander guys. As far as I am concerned, every high site should have one, but that's just me. I'm lazy so I do things right the first time.
