    Hi all,

    I have build a system of which currently uses 3 of these

    http://gsmalarmsystem.en.alibaba.co..._RTU_control_system_King_Pigeon_RTU_5011.html

    each of these units has its own sim card so you need to know which controllers number to send the individual commands to

    What I am looking for is a sms controller that contains 1 x sim card, has 25 or so 0V inputs, 25 or so relay drivable outputs and 2 x seperate analogue inputs that can measure the 2 x probes I am using in mA and the values can be sent to the phone on request.

    I have tried 3 x companies and aparently there is nothing off the shelf that has this amount of inputs and outputs.

    I am very happy with the 3 x units I am currently using its just a nuisance to know which no's to send the commands to.

    It is for a completed system that I am going to demo in a couple of weeks time if however it takes off like im very confident it will it wont be very good having 3 different sims in it.

    Another idea might be to get a phone that knows which phone numbers to send the sms commands to i.e "turn on light" and the phone or controller knows that text message goes to number phone no 12345678

    Any help on this is very welcomed.

    Thanks

    Hi all,

    I have contacted someone and they are saying 2 of these with the Telit GM862 GSM/GPRS module will do exactly what I am after..

    http://www.mikroe.com/eng/products/view/419/picplc16-v6-plc-system/

    For them to code it it will cost a lot of money but for the 2 boards and gsm module it will be around £300

    I am wondering how hard it will be for me to code this...bearing in mind over never coded anything before?

    Thanks
