Dear sir! Let us introduce ourselves. We're small team of electronic engineers and software developers. For years we designed complex solutions and electronics systems. One of the best solutions, which we ever had and which has worked for years is our electricity (or any other) meter reading via cellular (GSM) network. We have created and launched several successfully working systems (differ in size, complexity, amount of features implemented, etc). So we know what we're talking in. If needed we can present our solutions. We can sell you our working turnkey solution or perform adaptation of our solution on your conditions. Please provide feedback for our proposal in order we can know what to do next. Best regards, Vitaliy and teammates

Hi: I have a predesigned proyect and all the things ready to start as this is quite an interesting proyect I had in mind since quite a while. I have a friend who works in this kind of things and is the future of power reading for electricity companies. Big contracts. I have located the stores where they sell the electronics around and some other required things online. But i have another cheaper idea in mind. GSM can make the meter way too expensive. I made a a realistic time bidding (could be more time to develop). Those bidding 15 days have no idea on what they are bidding.

I have experience on remote control via GSM / Ethernet / Wifi. 3 years ago i developed GENSET controller which contrallable from Smartphone via GSM network. I ue SIMCOM's SIM900 GPRS modem for this. Customer can see all value and contactor states from Embedded webserve. Also in warning case GENSET send an SMS an EMAIL.

This sounds like a fun and exciting project to work on!!! Several years ago I developed all the software and firmware for a PIC based (16c67) system connected to a GSM phone via RS232 connection. This was more of a portable POS system. The microprocessor received SMS messages from the phone, parsed it for commands and then carried them out and sent back responses to number stored on the device. I think using this as a base, I can shorten the development cycle. The firmware was written in Assembler but if you go to a newer chip, I can translate to C. I have tools and an environment that supports remote development and testing. I hope we can discuss further. Langston

Hello, I am a little unsure on what step you are trying to contract out. Is it: A.) To build the device that meters electricity usage at the meter and communicates over serial. B.) The interface that connects the meter to gsm . C.) The interface to connect the gsm to a server and store data. D.) The interface for the user to see their usage. E.) All of the above If you are looking for B, I have a device with a service plan of only $0.59/month that will allow us to make readings at up to 1 minute intervals. The price is for most countries but does not specifically list Jordan. I can call the company and find out for sure. I can build all the steps listed here and build mobile apps to view the data. Let me know if you are interested, Nick Schild
