twisty 176 Posted July 2, 2018 Share Posted July 2, 2018 Hi. I understand it is possible to buy an alarm that sends a txt message when the water level gets too high. Does anyone know anything about them ? Cheers Quote Link to post Share on other sites
John B 106 Posted July 2, 2018 Share Posted July 2, 2018 Talk to Steve H, he set something like that up after exactly the same thing happened. Also Burnsco had something that attached to the battery terminals, but I suspect that was just a low battery alarm. Quote Link to post Share on other sites
Crazyhorse 47 Posted July 2, 2018 Share Posted July 2, 2018 Get a car burglar alarm that has GSM. Connect a float switch to one of the zone triggers and away you go! Our freezer has been switched off by others disconnecting the power in the past when we have been away from the boat on the hard. (One of those acts that make you think homicide..) so I now have a 5v "wall wort" plugged into the 240v that triggers the alarm via a relay. The moment the power goes off, the relay closes and I ring the yard. A VSR also switches over to battery so all good until the mains go back on. Quote Link to post Share on other sites

twisty 176 Posted July 2, 2018 Author Share Posted July 2, 2018 Thanks. I'll look into it Quote Link to post Share on other sites
Island Time 1,235 Posted July 2, 2018 Share Posted July 2, 2018 The SMS2 unit above is 3G/4G, GSM is general message service... Quote Link to post Share on other sites
Crazyhorse 47 Posted July 2, 2018 Share Posted July 2, 2018 $27.86 from china if you can stand the time waiting for it. Will do what you want (with a little ingenuity). Quote Link to post Share on other sites
Winter 42 Posted July 3, 2018 Share Posted July 3, 2018 The SMS2 unit above is 3G/4G, GSM is general message service... Really? The GSM logo is used to identify compatible devices and equipment. The dots symbolize three clients in the home network and one roaming client.[1] GSM (Global System for Mobile communications) is a standard developed by the European Telecommunications Standards Institute (ETSI) to describe the protocols for second-generation digital cellular networks used by mobile devices such as tablets, first deployed in Finland in December 1991.

That’s what Neil, the guy who designs and makes these things tells me. I’d only heard it refer to that network before as well. But Neil assured me that the unit takes both 3G and 4g sims. There is likely a message standard within the providers I guess, but I can find out if it’s that important for anyone. Quote Link to post Share on other sites
southernman 73 Posted July 4, 2018 Share Posted July 4, 2018 A lot of the cheap 3g/4g modems from China don't work here. We have just had a supplier to us pull out 200 modems out of gear supplied to us that does not work on either Voda, Spark or 2 Degrees. Quote Link to post Share on other sites
Crazyhorse 47 Posted July 4, 2018 Share Posted July 4, 2018 Mine works fine. 900mhz 2G on 2 Degrees sim. Quote Link to post Share on other sites
