AidenC Posted March 25, 2008 Posted March 25, 2008 Hi, a friend of mine has asked me to look into something for him, he currently runs a plumbing/heating service company and is looking into getting remote control of central heating in holiday homes, basically he has all the equipment ready to plug and play into a bt line, the only problem is these homes are in the middle of nowhere with no bt lines, so i was wondering if anyone knows of any solutions that have been tried and tested before ....ie GPRS routers etc, i did think about web and walk etc but it would need to be a stand alone router that wouldnt need a pc/laptop present.... (because hopefully if he gets the heating up and working he wants me to do the CCTV the same way ) Hope ive explained it well enough
TSS Posted March 31, 2008 Posted March 31, 2008 GPRS Routers = yes if the heating product is networkable (not seen one at a sensible price yet) - let me know if you find one GPRS router to BT / telco interface - sorry never seen one It might be possible to use someting like an Emizon 21 TCD but I don't know if the POTS interface is two way or not?

MrE Posted April 21, 2008 Posted April 21, 2008 GPRS Routers = yes if the heating product is networkable (not seen one at a sensible price yet) - let me know if you find oneGPRS router to BT / telco interface - sorry never seen one It might be possible to use someting like an Emizon 21 TCD but I don't know if the POTS interface is two way or not? The POTS port on the Emizon 21 TCD is two way, and is normally used outbound (from the TCD) using dial capture (ContactID/BSIA Fast Format/SIA) for alarm transmission, with inbound modem communications typically used for alarm panel remote maintenance etc. by ringing the panel and setting up a modem call. So there may be some way forward there. But the modem chip used is aimed at the security industry, so generally won't support a baudrate over 2400, which is gonna be painful for CCTV. More problems, Emizon 21 do not offer a GPRS only service as standard (at present) mainly due to the variable costs of airtime. Emizon includes the airtime in with the basic cost of the Emizon 21 service, based on normal usage where a fixed line is also present, presenting a fixed cost to the installer and taking the SIM management issues away. A custom product from Emizon might be possible where there is enough demand, so might be worth asking! I'd guess the mechanism used by the remote central heating system is basically a modem connection, so it would not look a lot different to the Galaxy Gold RMS or similar remote management systems using a POTS modem to operate. Emizon supply a tiny client PC program which provides a virtual serial port on the PC and then connects through the Emizon 21 network to the TCD Pots port as a transparent three wire serial port. It can also connect remotely to a RS232 3 wire interface (as used for the Texecom and Honeywell panels) which might be even simpler to use than the PSTN option. To get to using CCTV that way, using a PSTN port over GPRS is probably not a viable option, and you'll probably need to go to a fairly serious router setup. There are quite a few out there, google "GPRS Routers" brings up a load of them (though you'll probably need to dig deep!). Then you'll need to work out what to do at the other end to support the CCTV and the remote central heating system at the same time, manage your airtime and SIMS etc.
Alarm Co Posted April 21, 2008 Posted April 21, 2008 would the infinate alarm panel be any use with home automtion and in built gprs receiver? made by esp
arfur mo Posted April 21, 2008 Posted April 21, 2008 would a cheapy laptop working as a gateway with G3 card work on this kit? regs alan If you think education is difficult, try being stupid!!!!

Really easy! Premicell I used to fit these exchanges years ago, something like it must still be made? ----------------------------------------------------------------------------------------------------------------------------------- Life is like a box of chocolates, some bugger always gets the nice ones!

Woosh Posted April 22, 2008 Posted April 22, 2008 I have two used but working Nokia Premicells if you need one.
Neutech Posted April 23, 2008 Posted April 23, 2008 Just a wee not about Permicell These units are now illegal to connect to GSM networks and have been for a while now We used to install lots but were warned last year by o2 and vodafone not to use them again
